High performance physically based renderer in C++11

Overview

Tungsten Sample Render

The Tungsten Renderer

About

Tungsten is a physically based renderer originally written for the yearly renderer competition at ETH. It simulates full light transport through arbitrary geometry based on unbiased integration of the rendering equation. To do this, Tungsten supports various light transport algorithms such as bidirectional path tracing, progressive photon mapping, primary sample space metropolis light transport and more.

Tungsten is written in C++11 and makes use of Intel's high-performance geometry intersection library embree. Tungsten takes full advantage of multicore systems and tries to offer good performance through frequent benchmarking and optimization. At least SSE3 support is required to run the renderer.

Documentation

Documentation is planned, but currently unavailable (sorry!). A lengthy overview of features is available in the final project report written as part of the submission for the rendering competition, although that document may be outdated.

A small selection of example scenes can be found in data/example-scenes. There is also a material test scene found in data/materialtest, which contains the Tungsten material test ball that you can use to test different materials and lighting setups..

License

To give developers as much freedom as is reasonable, Tungsten is distributed under the libpng/zlib license. This allows you to modify, redistribute and sell all or parts of the code without attribution.

Note that Tungsten includes several third-party libraries in the src/thirdparty folder that come with their own licenses. Please see the LICENSE.txt file for more information.

Compilation

Windows + MinGW

To build using MinGW, you will need a recent CMake + gcc version. CMake binary distributions are available here. I recommend using MinGW-w64 available here.

In the root folder of the repo, use these commands in an MSYS shell to build:

./setup_builds.sh
cd builds/release
make

The binaries will be placed in the build/release directory after buiding.

Optionally, you can install the Qt framework to build the scene editor utility. If Qt is not detected during setup, the scene editor will not be built (you will still be able to use the renderer).

Windows + MSVC

To build using MSVC, you will need a recent CMake version and MSVC 2013. CMake binary distributions are available here.

After installing CMake, double click the setup_builds.bat file. The MSVC project will be created in the folder vstudio. Open the vstudio/Tungsten.sln solution and press F7 to build.

Linux

Building on Linux works just like building on MINGW.

Usage

The core renderer can be invoked using

tungsten scene.json

You can also queue up multiple scenes using

tungsten scene1.json scene2.json scene3.json

and so forth. All renderer parameters, including output files, are specified in the json file.

You can test your local build by rendering the material test scene in data/materialtest/materialtest.json.

You can also use

tungsten --help

for more information.

Code structure

src/core/ contains all the code for primitive intersection, materials, sampling, integration and so forth. It is the beefy part of the renderer and the place to start if you're interested in studying the code.

src/thirdparty contains all the libraries used in the project. They are included in the repository, since most of them are either tiny single-file libraries or, in the case of embree, had to be modified to work with the renderer.

src/tungsten contains the rendering application itself, which is just a small command line interface to the core rendering code.

All other folders in src are small utilities described below.

Additional utilities

Apart from the core renderer, Tungsten also comes with several tools to make content creation easier.

tungsten_server

This is a standalone version of the renderer that comes with a built-in HTTP status server.

It will serve the following files:

  • /render: The current framebuffer (possibly in an incomplete state).
  • /status: A JSON string containing information about the current render status.
  • /log: A text version of the render log.

Use

tungsten_server --help

for more information.

scenemanip

scenemanip comes with a range of tools to manipulate scene files, among others the capability to package scenes and all references resources (textures, meshes, etc.) into a zip archive.

Use

scenemanip --help

for more information.

hdrmanip

hdrmanip comes with a few useful tools for manipulating HDR output files produced by the renderer. Where available, we recommend using established image manipulation tools, but where HDR support is sparsely available, this tool can be useful.

To convert an HDR image to low dynamic range, use

hdrmanip -o output.png input.exr

You can also specify the tonemapping operator to be applied when converting. For example, to use a filmic tonemap, use

hdrmanip --tonemap filmic -o output.png input.exr

To adjust the exposure of an HDR file, you can use

hdrmanip --exposure -1.0 -o output.exr input.exr

If you don't specify an output file, the tool will overwrite the input file. You can also modify several input files at once. For example, you can use

hdrmanip --exposure -1.0 input1.exr input2.exr input3.exr

to adjust the exposure of several files at once.

If you don't want to overwrite the input files, you can specify an output directory with -o

hdrmanip -o outputdir --exposure -1.0 input1.exr input2.exr input3.exr 

When specifying multiple files, -o is interpreted as an output directory, and its file extension is ignored. If you want to convert multiple input files to a different file format or even low dynamic range, you can use --file-type

hdrmanip --file-type png input1.exr input2.exr input3.exr

Finally, hdrmanip also supports merging multiple HDR files together. This is useful when you split up a render across several machines and want to average the outputs to get a less noisy image. You can use --merge for this

hdrmanip --merge -o output.exr input1.exr input2.exr input3.exr

Of course, you can also adjust the exposure and convert to low dynamic range while merging, all in one step.

Use

hdrmanip --help

for more information.

obj2json

The command

obj2json srcFile.obj dstFile.json

will parse the Wavefront OBJ srcFile.obj, including object hierarchy and materials, and create a scene file dstFile.json reproducing hierarchy and material assignments.

In addition, meshes in the OBJ file will be automatically converted and saved to Tungsten's native *.wo3 mesh format, which significantly reduces loading time for large meshes. This may create a large number of new files - consider pointing the dstFile.json path into an empty subfolder to avoid file clutter.

json2xml

The command

json2xml srcFile.json dstFile.xml

will parse the scene file srcFile.json and convert it to an XML scene description compatible with the Mitsuba renderer. All *.wo3 files will be converted to Mitsuba compatible OBJs, which may create a large number of new files - consider putting dstFile.xml into an empty subfolder to avoid file clutter.

Note that this tool does not experience heavy testing and does not support all features of Tungsten, so it may not always work as expected.

editor

This is a minimalist scene editor written in Qt and OpenGL. It supports camera setup, manipulating transforms, compositing scenes and a few more features that I found useful.

It is usable, but a few crucial features are currently missing from it (including documentation). The code is neither exceptionally clean nor stable, so use at your own risk.

  • the default far plane, near plane, and clip coordinates

    the default far plane, near plane, and clip coordinates

    Hello! I'm still learning computer graphics. I want to try reprojection in the TAA algorithm:

    where p is the pixel's homogeneous coordinate:

    Therefore, I need to get the view matrix and projection matrix. The up, look at, and camera position can be found in JSON, but I still don't know the far plane and near plane to compute the projection matrix. I noticed that the far plane and near plane in the PreviewWindow.hpp are 100 and 0.01. Are the values the same inside the renderer?

    Also, I'm not sure about the component z of the coordinate. I've made tungsten outputted depth buffers, but I don't know how to normalize them. Is the range of z (-1, 1), or (0, 1)? I guess z is somewhat like depth_buffer / (far - near). Am I correct?

    Thanks.

  • Implementation of cylinder primitive?

    Implementation of cylinder primitive?

    Hi Mr. Bitterli,

    I was introduced to your renderer by a friend, and was impressed by the result and performance. As I'm trying to render some molecular pictures, a "cylinder" geometry would be very helpful for showing chemical bonds. Without any knowledge of computer graphics, I read the implementation of other primitives in src/core/primitives and tried to implement the cylinder primitive by mimicking them. My first draft was able to compile, but the cylinder is not showing up in the rendered results, except some reflections on a sphere. I have very little understanding of how the rendering works, so many of the functions may be done terribly wrong. If you have a little time, could you please take a look at it? (https://github.com/yudongqiu/tungsten/blob/master/src/core/primitives/Cylinder.cpp)

    Any hint on my mistakes, or references that could help me understanding it, would be greatly appreciated. It would be also great that if you think writing it from scratch is better than looking at mine. 😄 Thanks a lot!

    Best,

    Yudong Qiu

  • Fix nearest-neighbor interpolation of cached reconstruction filter

    Fix nearest-neighbor interpolation of cached reconstruction filter

    Hi Benedikt!

    I was implementing film and reconstruction functionality in my renderer and I learned a lot from your implementation. I think that I stumbled upon a very tiny problem in your implementation that can have a noticeable effect on the result however.

    When you retrieve the cached filter value, you effectively floor the continuous array index (via int cast) rather than rounding it to the closest integer. This will pick the "wrong" value (i.e. not the nearest neighbor) about 50% of the time as shown in the illustration below.

    Since we are dealing with positive values, shifting the continuous index to the left by adding 0.5 before flooring is enough to achieve rounding. Here's a comparison between direct filter evaluation as reference, floor and round (using the Lanczos filter):

    diff

    I removed the normalization of _filter to achieve the same intended filter for these comparisons, since direct evaluation is not normalized.

  • About customizing ray directions

    About customizing ray directions

    Hi Benedit.

    I know the path tracing algorithm demands the ωo generated randomly, I want to customize the ωo of the first bounce of each ray though.

    I've tried to fathom tungsten's core codes but can't get everything clear, for I just started learning pbrt. I've made PathTracer.cpp load an exr file describing the ωo of each pixel, but I have no idea where I can assign them. I guess the random generation happens in the class PathSampleGenerator, and handleSurface(), estimateDirect(), sampleDirect(), and chooseLight() in the TraceBase.cpp need modifications. Could you teach me a bit?

    Thanks. 😊

  • Cannot Compile Master on Windows

    Cannot Compile Master on Windows

    I'm unable to compile master commit 88ea02044dbaf20472a8173b6752460b50c096d8 on Windows as neither OpenVDB nor OpenEXR are being correctly linked to the executable.

    I am using a vcpkg environment with boost, tbb and openexr installed and have compiled openvdb myself. The paths are correctly set in cmake, but I run into unresolved external symbols and could not find header [insert an openexr header] type errors.

    I'm not sure how to debug this, so if you have an already compiled version that I can use that'd be great. If not, I'd be grateful for any pointers as to what I should investigate first.

DeepRTS is a high-performance Real-TIme strategy game for Reinforcement Learning research written in C++

DeepRTS is a high-performance Real-TIme strategy game for Reinforcement Learning research. It is written in C++ for performance, but provides an python interface to better interface with machine-learning toolkits. Deep RTS can process the game with over 6 000 000 steps per second and 2 000 000 steps when rendering graphics. In comparison to other solutions, such as StarCraft, this is over 15 000% faster simulation time running on Intel i7-8700k with Nvidia RTX 2080 TI.
