GETTING STARTED
---------------

This README file exists only to provide you a brief roadmap to the
contents of the BRL-CAD distribution.

Some platforms have additional platform-specific documentation that
should be consulted after reading this file:

  doc/README.AIX        -- IBM's Advanced Interactive eXecutive OS
  doc/README.BSD        -- FreeBSD, NetBSD, OpenBSD, etc.
  doc/README.IRIX       -- SGI IRIX and IRIX64
  doc/README.Linux      -- Various Linux distributions
  doc/README.MacOSX     -- Apple Mac OS X
  doc/README.Solaris    -- Oracle Solaris, OpenIndiana (Illumos), etc.
  doc/README.Windows    -- Microsoft Windows

The information on how to install and operate the software, to become
involved with the development of the package, or to run the benchmark
performance test suite have each become sufficiently large that their
details are covered in more detail in standalone documents.  For more
details on what BRL-CAD provides, see the documentation provided on
the website at http://brlcad.org/.

Information relevant to those interested in the source code is
contained in the HACKING and COPYING files.  See doc/benchmark.tr file
for benchmark suite information.  There is a variety of other
documentation and information also available in the doc/ directory.

Please note that this distribution package does not include the
various military-specific model analysis tools such as MUVES, GIFT,
SAR, SLAVE, VAST, etc., nor does it include any military geometry
databases.  If you desire to have access to this material, please
contact one of the BRL-CAD developers.


COMPILE AND INSTALL
-------------------

In order to compile and install BRL-CAD from a source distribution,
the CMake ( http://www.cmake.org ) configuration tool is requird.

The following steps should result in a successful install:

  tar -xvzf brlcad-VERSION.tar.gz
  mkdir brlcad-VERSION/build
  cd brlcad-VERSION/build
  cmake .. -DBRLCAD_ENABLE_STRICT=OFF -DCMAKE_BUILD_TYPE=Release
  make -j4
  make install

See the INSTALL file for explanation of the various configuration
options available when building BRL-CAD.

Once the build completes and assuming you have proper filesystem
permissions, you should be able to begin the installation by running
the "make install" .  By default, the package is configured to install
entirely into /usr/brlcad/.

You will need to add /usr/brlcad/bin to your path (or whatever path the
variable CMAKE_INSTALL_PREFIX was set to during configure) in order for
the BRL-CAD binaries to be in your path.


BENCHMARK
---------

After the build successfully completes, you will be able to verify
basic functionality by running the BRL-CAD Benchmark.  Running the
benchmark suite is integrated into the build system such that any time
after running CMake (in the cmake gui, configure and generate must both
be performed) you may run:

  make benchmark

If the build is successful, you will see "CORRECT" numbers and a
performance summary at the end.  The "vgr" line effectively shows you
approximately how much faster your machine is to a VAX 11/780.  After
installing BRL-CAD, you may run the 'benchmark' tool as well to run
the BRL-CAD Benchmark.

See the paper in doc/benchmark.tr for information on analyzing and
comparing the results of the benchmark tests in more detail.


COMMUNICATION
-------------

There are various BRL-CAD mailing lists available including three
developer-oriented lists, a user list, and a read-only news
announcement list:

BACKGROUND INFORMATION
----------------------

BRL-CAD is the primary tri-service solid modeling CAD system used by
the U.S. military to model weapons systems for vulnerability and
lethality analyses.  The solid modeling system is frequently used in a
wide range of military and industrial application including in the
design and analysis of vehicles, mechanical parts, and architecture.
The package has also been used in radiation dose planning, medical
visualization, computer graphics education, CSG concepts and modeling
education, and system performance benchmark testing among other
purposes.

Actively developed since 1979, BRL-CAD is a collection of more than
400 tools, utilities, and applications comprising more than a million
lines of source code.  BRL-CAD supports a great variety of geometric
representations including an extensive set of traditional CSG
primitive implicit solids such as boxes, ellipsoids, cones, and tori,
as well as explicit solids made from closed collections of Uniform
B-Spline Surfaces, Non-Uniform Rational B-Spline (NURBS) surfaces,
n-Manifold Geometry (NMG), and purely faceted mesh geometry.  All
geometric objects may be combined using boolean set-theoretic CSG
operations including union, intersection, and difference.

BRL-CAD has been under active development for more than 20 years with
a portability heritage that includes systems such as a DEC VAX-11/780
running 4.3 BSD; DECStations running ULTRIX; Silicon Graphics 3030, 4D
"IRIS", O2, Onyx, and Origin systems running various versions of IRIX;
Sun Microsystems Sun-3 and Sun-4 Sparcs running SunOS; the Cray 1,
Cray X-MP, Cray Y-MP, and Cray 2 running UNICOS; DEC Alpha AXP running
OSF/1; Apple Macintosh II running A/UX; iPSC/860 Hypercube running
NX/2; the Alliant FX/8, FX/80, and FX/2800; Gould/Encore SEL PowerNode
6000/9000 and NP1; NeXT workstations; IBM RS/6000; HPPA 9000/700
running HPUX; Ardent/Stardent; Encore Multi-Max; and much much more.
BRL-CAD's extensive portability of course also includes a plethora of
common desktop and server versions of BSD, IRIX, Solaris, Mac OS X,
Linux, and Windows.

The BRL-CAD package is intentionally designed to be extensively
cross-platform and is actively developed on and maintained for many
common operating system environments including for BSD, IRIX, Linux,
Solaris, Mac OS X, and Windows among others.  The entire package is
distributed in binary and source code form as free open source
software (FOSS), provided under Open Source Initiative (OSI) approved
license terms.  BRL-CAD was released as open source in December 2004.
See the COPYING file for more details.

Best Wishes,
The BRL-CAD Development Team

  • Support to allow to change to quad view at runtime

    Support to allow to change to quad view at runtime

    I think I may have commit access but I wasn't 100% sure about this change. This was more just an educational exercise to get my environment setup and make a small code change. Before I commit to the main I wanted to make sure:

    1. I was on the right track with this change. This is the way to do this.
    2. the change was compliant with all the rules for committing code outlined in the HACKING document
    3. This was a change we are interested in.

    I did some very minor code clean up of the code that was already there. Mostly I just added the capability to change back and forth to single view and quad view. There is preexisting code that is not compliant with HACKING document. If I'm on the right track I will clean up some of the other issues I have seen.

  • Issues with musl libc

    Issues with musl libc

    I tried to build brlcad-7.32.4-1 on a musl-based linux system (Void Linux) and I encountered various issues. These don't occur on the glibc version of Void Linux.

    1. https://github.com/BRL-CAD/brlcad/blob/0f3f0625110d498906b1556c6cd79f8b4088e3d7/src/libbu/affinity.c#L61-L65 It looks like neither of musl and glibc have cpuset_t, while both have cpu_set_t, but for some reason HAVE_CPU_SET_T is not defined with musl. I think the ifdef could be removed completely.

    2. misc/tools/env2c/env2c.cxx segfaults. The problem is not related to brlcad and could be fixed by using a link flag such as -Wl,-z,stack-size=2097152. However the LDFLAGS environment variable is not used when building this program, is this intentional?

    3. gethostbyname(3), used in src/util/ttcp.c, is no longer in POSIX. glibc provides it by default, while musl requires an appropriate feature macro, e.g. #define _POSIX_C_SOURCE 200112L.

    4. Various programs crash at runtime during build with several errors of the kind Error relocating: symbol not found. Any ideas about what could be the cause?

    The logs below illustrate the last problem, after I applied patches to fix the first three.

  • Material command gqa rtweight art

    Material command gqa rtweight art

    gqa:

    • added functionality for new material object representation. Keeps old functionality from .density table but adds the option for material objects to be used in gqa (with or without ids)

    rtweight:

    • same as gqa for weight calculation
    • changed the order of initialization in rt/main.c so that we could use the new material objects from the database

    attr:

    • Added new standard attribute "material_name" to eventually replace "material_id". Could possibly be renamed to "material" when this change happens

    testing:

    • unit testing on material command
    • integration testing on rtweight
    • integration testing on art

    Sorry this merge is so big but unfortunately all of the changes were intermingled with each other so I couldn't find a way to separate them through rebasing or cherry-picking commits :(

And After clicking Abort it is cancelling the whole installation.

    I have no idea What's causing this error.

    Am I missing something ? like Microsoft Visual C++ Reditributable ? Should I try to install with .msi file ?

    ----------------------------------------------------------------------
    
    This major release of BRL-CAD introduces significant updates to core
    library infrastructure.  The update includes restructuring of nearly
    all of BRL-CAD's display infrastructure in preparation for upcoming
    significant GUI changes.  This release also fixes over fifty of
    BRL-CAD's command-line utilities so they work properly on Windows.
    This is likely the last major release of BRL-CAD on Subversion
    infrastructure with BRL-CAD's imminent migration to Git.

    This major release of BRL-CAD is the first release requiring
    compiler support for the C++11 language standard when building.
    (This change is not user visible, but will be significant to those
    using BRL-CAD in their own software development efforts.)
    
    This release introduces a new "-d" option to the mater command,
    supporting direct embedding of .density file information in a
    .g database for use by commands such as gqa and rtweight.
    
    Also present in this release are a fix for commands that work with
    multiple .g files and support for raytracing MGED scenes with large
    numbers of active objects.
    
    A number of commands and tools previously listed as deprecated are
    removed in this release, including in particular MGED commands
    specific to MUVES.

    ----------------------------------------------------------------------
    
    This major release of BRL-CAD incorporates a new feature for caching
    of raytrace acceleration structures used when working with explicit
    boundary representation (BREP) Non-uniform Rational Basis Spline
    (NURBS) solids.  This will result in significant improvements to
    run times when repeatedly raytracing BREP solids.
    
    Support for terrain import has been significantly expanded with the
    addition of a new Geospatial Data Abstraction Library (GDAL) based
    importer to the gcv conversion tool.  GDAL brings with it support for
    dozens of different terrain data formats.
    
    Also new in this release are a greatly improved graphical geometry
    overlap resolving tool and support in the MGED search command for
    an "exec" option which will allow users to execute MGED commands
    on search results.
    
    The MGED facetize command for generating polygonal geometry from
    BRL-CAD objects has received significant attention, including the
    incorporation of a "per-region" conversion mode, new conversion
    methodologies and usability enhancements.

    ----------------------------------------------------------------------
    
    Among a variety of bugs fixed, the patch corrects a critical error in
    BoT triangle mesh ray tracing.  For improved performance, it also
    changes the default frame buffer display behavior to fully buffer ray
    tracing images instead of displaying them incrementally.  A variety of
    MGED commands see improvements too with 'ls' now supporting listing
    objects by their on-disk size and the 'simulate' command applying
    forces on objects (e.g., gravity) with greater ease.  Not yet
    complete, there is a new interface being developed for resolving
    overlaps more efficiently, currently under development and usability
    testing with select users.  Lastly, a number of dependencies were
    upgraded, including Tcl/Tk, in order to patch security vulnerabilities
    and address portability issues.

    --- 2016-08-08  Release 7.26.0                                     ---
    ----------------------------------------------------------------------
    
    This major release of BRL-CAD culminates several years of development
    effort to provide robust explicit boundary representation (BREP)
    Non-uniform Rational Basis Spline (NURBS) import and ray tracing
    analysis support.  Compared to previous polygonal mesh (BoT) methods,
    NURBS offer superior interoperability with other CAD systems, faithful
    shape-preserving import, and significantly reduced model sizes.  NURBS
    may be imported from the ISO STEP (AP203) and Rhino 3DM file formats,
    both with improved hierarchy preservation and entity support.
    
    Unprecedented in BRL-CAD's history, this release initiates steps to
    significantly reduce complexity and improve usability.  Many features
    are being consolidated, reorganized, and removed via BRL-CAD's
    deprecation process.  There are widespread documentation system
    enhancements including new manual pages, improved command usage,
    better help facilities, and more.
    
    This release introduces the 'gcv' and 'icv' tools for geometry and
    image conversion respectively.  These plugin-architecture tools are
    intended to eventually consolidate and replace all of BRL-CAD's
    conversion and processing functionality into an easy universal
    interface for users and application developers.  GCV currently
    supports import and export of STL, 3DM, OBJ, VRML, and FASTGEN
    geometry as well as mesh decimation, facetization, and solidity
    testing.  The new FASTGEN exporter implements extensive compatibility
    feature mapping for round-trip geometry conversion.
    
    Ray tracing performance on Windows is vastly improved on symmetric
    multiprocessing (SMP) multicore and multiple CPU systems.  Implemented
    as 'datum' objects, BRL-CAD provides new modeling support for
    reference points, lines (axes), and planes.  Major features still
    under experimental development include NURBS Boolean evaluation, a new
    marching cubes method for polygonal mesh export, rigging joints for
    constrained geometry articulation, and an OpenCL-accelerated high
    performance ray tracing pipeline.

    ----------------------------------------------------------------------
    --- 2013-06-13  Release 7.24.0                                     ---
    ----------------------------------------------------------------------
    
    This major update to BRL-CAD comes after nearly a full year of
    development.  This is the alpha release unveiling of Archer/MGED, a
    preliminary interface update to BRL-CAD's graphical geometry editor.
    As alpha software, this new MGED prototype aims to provide functional
    feature parity with the antecedent MGED interface while introducing
    various changes.  Included is an integrated graphical tree view, a
    single window framework, drag-and-drop geometry editing, information
    panels, shortcut buttons, improved polygonal mesh and 2D sketch
    editing, level-of-detail wireframes, NURBS shaded display support, and
    much more.  Prior to upcoming beta testing where the emphasis will
    predominantly be on stability and usability, this alpha status
    solicits feedback from the community on capability and features.
    
    This release also includes various improvements to BRL-CAD's ray
    tracing infrastructure including CPU thread affinity locking for
    faster performance, more consistent grazing hit behavior, expanded
    volume and surface area calculations, numerous bug fixes, and more
    robust NURBS evaluation.  Following BRL-CAD's interface deprecation
    policy (see CHANGES file), the Jove text editor is no longer being
    bundled.  Numerous converters receive robustness improvements
    including the STEP, Patch, and 3DM importers.

    SECOND REVISION: The first posting of the 7.22.0 release of BRL-CAD
    for Mac OS X included dependencies to a non-default library causing
    MGED to fail to start properly.  This second post fixes that issue.
    
    This is the debut release of BRL-CAD for Mac OS X providing an
    improved drag-n-drop installation.  The graphical application launched
    by default is BRL-CAD's "mged" geometry editor.  However, also
    included within the application bundle is a complete installation of
    BRL-CAD's 400+ other command-line applications.  They are located in
    the Contents/Resources/brlcad subdirectory of the application bundle.
    
    ----------------------------------------------------------------------
    --- 2012-06-25  Release 7.22.0                                     ---
    ----------------------------------------------------------------------
    
    After many months of development, this release includes hundreds of
    fixes for source code defects, logic and memory management bugs,
    potential security vulnerabilities, and numerous other issues reported
    by Coverity Static Analysis.  While having participated in the
    Coverity Scan Initiative since inception in 2006, this release marks a
    completion milestone with the review and resolution of all reported
    issues, more than 2100 overall.  Every defect was inspected, code
    modifications were peer-reviewed, critical features were tested, and
    user-visible changes were documented.  Along with other on-going
    improvement efforts such as treating all compiler-generated warnings
    as errors, time and attention continues to be put forth towards
    improving BRL-CAD's maintainability and source code quality.
    
    Development of BREP/NURBS representation support within BRL-CAD
    continues to mature with this release including ray tracing
    improvements, tighter bounding boxes for better performance, progress
    converting from traditional implicit+CSG representations to NURBS+CSG,
    wireframe improvements, and a thorough verification and validation
    (V&V) review for analysis suitability.  The V&V review compared
    BRL-CAD's primitives in implicit, polygonal mesh, and NURBS form
    evaluating more than a dozen separate tests looking for differences in
    rendering, curvature, presented areas, volume, and more.  The review
    identified a couple minor issues that were inspected and fixed but
    successfully demonstrated the viability of using our BREP/NURBS
    implementation for geometric representation and analysis purposes.
    
    This release introduces numerous major feature developments including
    the initial implementation of a new physics simulation capability, a
    new ambient occlusion rendering mode, and the integration of rtwizard
    into Archer.  The simulation system was developed by Abhijit Nandy
    under the European Space Agency's 2011 Summer of Code in Space (SOCIS)
    program; and it allows BRL-CAD geometry objects to dynamically
    interact with each other (e.g., collision detection, friction) or with
    the environment (e.g., gravity).  Ambient occlusion is a shading
    method that helps add considerable realism and feature definition to
    renderings, enabled within rt using the "set ambSamples=128" command.
    The rtwizard rendering interface was extended to work as a
    command-line tool (useful for scripting) and was integrated within
    Archer as the underlying rendering interface.
    
    Conversion support continues to be a development priority with
    significant importer enhancements for the STEP, OBJ, COMGEOM, FASTGEN,
    and RAW file formats.  The STEP importer in particular receives
    several updates, support for importing assembly hierarchies, and is in
    the process of being fully ported to Windows.  This release also fixes
    more than 40 user-visible bugs including a significant database
    corruption issue.  A database corruption issue was discovered and
    fixed affecting 64-bit big endian platforms (e.g., IBM Power Series
    supercomputers) when writing out ebm, dsp, vol, and hf primitives.
    
    BRL-CAD's documentation continues to be extended, improved, and
    translated due to the sustained efforts of several contributors.
    Manual page documentation is now available on Windows through the
    'brlman' command and within MGED.  Several utilities and commands that
    previously had no documentation now have manual pages; many others
    received corrections and improvements.  The introductory article
    "About BRL-CAD" is now available in Russian, Italian, and Armenian.

    ----------------------------------------------------------------------
    --- 2011-05-27  Release 7.20.0                                     ---
    ----------------------------------------------------------------------
    
    This release marks the introduction of a new CMake build system for
    BRL-CAD.  CMake is cross-platform build system infrastructure capable
    of generating native build system logic for a wide variety of
    operating systems and compilation environments.  Cliff Yapp has been
    diligently working on this adaptation for a number of months in order
    to simplify the task of maintaining BRL-CAD on multiple platforms.
    
    Previously, two separate build systems were being maintained: one
    system (GNU Autotools) for Linux, UNIX, and BSD platforms (including
    Mac OS X); and another separate system (Microsoft Visual Studio) for
    Windows.  The new build system supports all platforms (including
    Windows) from the same build logic.  This eliminates the need to
    manually update multiple build systems and improves BRL-CAD
    cross-platform maintainability.

    --- 2011-04-12  Release 7.18.4                                     ---
    ----------------------------------------------------------------------
    
    After considerable development, this release includes the preliminary
    integration of our high-performance Triangle Intersection Engine (TIE)
    with BRL-CAD's LIBRT raytrace library.  TIE uses specialized
    acceleration techniques for faster raytracing of triangle mesh models.
    TIE was experimentally developed over several years as part of
    BRL-CAD's Advanced Distributed Ray Tracer (ADRT) tool suite.  As this
    is the initial integration, TIE is available but presently disabled by
    default.  The engine optimization is configurably integrated with
    LIBRT mesh (BoT) raytracing and optionally enabled via settings
    available in RT and MGED.  Initial testing of "real-world" models shows
    average improvements around 20-60% while individual meshes with high
    (1M+) face counts are rendering more than 2000% faster than before.
    
    Also included in this release is the development of a new "shp-g"
    geometry importer for Shapefile data.  Shapefiles are a common file
    format for storing geospatial vector data commonly used by geographic
    information systems (GIS) software.  Shapefiles may be imported as 2D
    sketch geometry that can be extruded to a 3D representation.
    
    * fixed units conversion bug with mged 'title' command - Bob Parker
    * fixed memory management crash in the dem-g importer - Richard Weiss
    * fixed edcolors so it retains and accepts colors again  - Cliff Yapp
    * support for applying matrix edits to revolve primitives - Dongxu Li
    * fixed mged 'red' command bug on Windows - Sean Morrison, Cliff Yapp
    * support matrices over halfspaces within combinations - Sean Morrison
    * fixed archer and rtwizard startup failure bug on Mac - Sean Morrison
    * fixed bug starting up the Combination Editor in mged - Sean Morrison
    * mged 'mater' command interactive prompting restored - Sean Morrison
    * added pix2fb and fb2pix screenshot commands to archer - Bob Parker
    * fixed bug running nirt on a Windows command terminal - Bob Parker
    * improved wireframe updating when editing within mged - Sean Morrison
    * added -T bot_mintie BoT optimization options to nirt - Sean Morrison
    * fixed Windows display manager bug when drawing strings - Bob Parker
    * mged command-click zoom binding for one button mice - Sean Morrison
    * removed 'txyz-pl' utility tool in favor of 'xyz-pl' - Sean Morrison

    BRL-CAD's ray tracing support for NURBS boundary representation
    geometry objects continues to be developed towards providing a robust
    foundation for supporting multiple-representation geometry.  This
    release includes several NURBS ray tracing bug fixes, robustness
    improvements, and trimming enhancements.
    
    MGED receives a lot of attention towards improved stability with
    numerous troublesome bugs getting fixed (e.g., "the Mac input bug"),
    restoration of behavior for various introspective commands, and
    continued feature integration with Archer.  MGED's wireframe display
    gets a substantial 5x-10x performance improvement for non-Windows
    platforms while MGED on Windows now supports 64-bit releases and
    restores command-line scripting support.
    
    Archer gets a user interface facelift with the introduction of a new
    geometry browser, list view, buttons, and much more.  As Archer
    approaches feature parity with MGED, it gets closer to an official
    alpha release status as BRL-CAD's next generation geometry editor.

Supplemental source code for "A Halfedge Refinement Rule for Parallel Catmull-Clark Subdivision".

This repository provides source code to reproduce some of the results of my paper "A Halfedge Refinement Rule for Parallel Catmull-Clark Subdivision". The key contribution of this paper is to provide super simple algorithms to compute Catmull-Clark subdivision in parallel with support for semi-sharp creases. The algorithms are compiled in the C header-only library CatmullClark.h. In addition you will find a direct GLSL port of these algorithms in the glsl/ folder. For various usage examples, see the examples/ folder.

Style guides for Google-originated open-source projects

Every major open-source project has its own style guide: a set of conventions (sometimes arbitrary) about how to write code for that project. It is much easier to understand a large codebase when all the code in it is in a consistent style.
