Generator - A procedural geometry generation library.

The purpose of this library is to easily generate procedural meshes of geometric primitives such as spheres, boxes, cones, cylinders etc.

Generator is not a graphics library. It will only produce data for any graphics library to use.

Compiling

To compile you will need a C++11 compatible compiler (tested with gcc 4.8) and cmake (tested with cmake 2.8).

Generator needs a vector math library to work. It will use GML. There are no other dependencies.

Compile with:

cmake .
make

If GML is not in the include path, you can give it's path with: -DGML_INCLUDE_DIR command line argument.

cmake . -DGML_INCLUDE_DIR=path/to/gml
make

The library libgenerator will be in the lib directory.

In images directory there is a program called generate that can generate svg test images.

You can generate documentation with Doxygen. Run generate in the images directory before doxygen as the documentation uses images generated by it.

Usage

Make sure that that Generator and the GML math library are in the include path.

To include all primitives use:

#include <generator/generator.hpp>

To include individual primitives include a header file that has the same name as the primitive class.

#include <generator/SphereMesh.hpp>
#include <generator/HelixPath.hpp>
#include <generator/CircleShape.hpp>

If you'd prefer to use GLM, a similar (but more heavyweight) library, build with the #define GENERATOR_USE_GLM.

Everything in the library is under the namespace generator. The examples in this document will omit this namespace.

You will also need to link with libgenerator.

Coordinate systems

Generator uses a right handed coordinate system, just like OpenGL does.

All angles are in radians positive, with the direction being counterclockwise when looking towards the axis.

Vertices in triangles are in counterclockwise order.

All calculations are done double precision.

Concepts

There are two main concepts in the library: "primitives" and "generators".

Primitives produce generators. Generators generate values such as vertex coordinates.

Primitives

There are three types of primitives: "shapes", "paths" and "meshes". All primitive class names end with their type e.g. SphereMesh, HelixPath or CircleShape.

Shapes

Shapes are a set of ShapeVertexes on the 2d xy-plane and a set of Edges connecting them.

class ShapeVertex {
public:
	gml::dvec2 position;
	gml::dvec2 tangent;
	gml::dvec2 normal() const noexcept;
	double texCoord;
};

class Edge {
public:
	gml::uvec2 vertices;
};

All shapes have these methods:

EdgeGenerator edges() const noexcept;
VertexGenerator vertices() const noexcept;

Where EdgeGenerator and VertexGenerator can be a arbitrary types. The shape must outlive the generators it produces. If the shape is mutated the generators are invalidated. Shapes can be mutated only via assignment. The are no setter methods.

Available shapes are:

BezierShape
CircleShape
GridShape
LineShape
ParametricShape
RectangleShape
RoundedRectangleShape

Paths

Paths are a set of PathVertexes in 3d space and a set of Edges connecting them.

class PathVertex {
public:
	gml::dvec3 position;
	gml::dvec3 tangent;
	gml::dvec3 normal;
	gml::dvec3 binormal() const noexcept;
	double texCoord;
};

All paths have these methods:

EdgeGenerator edges() const noexcept;
VertexGenerator vertices() const noexcept;

EdgeGenerator and VertexGenerator are arbitrary types.

Available paths are:

HelixPath
KnotPath
LinePath
ParametricPath

Meshes

Meshes are a set of MeshVertexes in 3d space and a set of Triangles connecting them.

class MeshVertex {
public:
	gml::dvec3 position;
	gml::dvec3 normal;
	gml::dvec2 texCoord;
};

class Triangle {
public:
	gml::uvec3 vertices;
};

All meshes have these methods:

TriangleGenerator triangles() const noexcept;
VertexGenerator vertices() const noexcept;

Again, TriangleGenerator and VertexGenerator can be any type.

Available meshes are:

BezierMesh
BoxMesh
CappedConeMesh
CappedCylinderMesh
CappedTubeMesh
CapsuleMesh
ConeMesh
ConvexPolygonMesh
CylinderMesh
DiskMesh
DodecahedronMesh
PlaneMesh
IcosahedronMesh
IcoSphereMesh
ParametricMesh
RoundedBoxMesh
SphereMesh
SphericalConeMesh
SphericalTriangleMesh
SpringMesh
TeapotMesh
TorusMesh
TorusKnotMesh
TriangleMesh
TubeMesh

Generators

Except for cached values (which should be considered an implementation detail), primitives don't store any data (vertices etc). All data is generated on the fly with generators.

Generators are made by calling edges(), triangles() or vertices() on the primitive. Generators are lightweight objects analogous to iterators. They typically only contain a pointer back to the Primitive and state info for iteration. Any number of generators for the same primitive can exist at the same time.

Generators can have arbitrary types. Use the keyword auto to avoid the need to explicitly specify them.

SphereMesh sphere{};
auto vertices = sphere.vertices();

For cases where auto cannot be used, the helper class templates EdgeGeneratorType, TriangleGeneratorType and VertexGeneratorType are provided in util.hpp.

typename VertexGeneratorType<SphereMesh>::Type vertices = sphere.vertices();

If the generator type is known only at runtime, the type-erasing class template AnyGenerator can be used (in AnyGenerator.hpp).

AnyGenerator<MeshVertex> vertices = sphere.vertices();

If the generator's primitive type is known at compile time, the AnyShape, AnyPath, and AnyMesh types may be used for respectively storing shapes, path and meshes.

All generators have the following methods:

bool done() const noexcept;
Value generate() const;
void next();

Where Value can be Edge, Triangle, ShapeVertex, PathVertex or MeshVertex.

These methods can be used to iterate over all values in the generators.

SphereMesh sphere{};
auto vertices = sphere.vertices();
while (!vertices.done()) {
	MeshVertex vertex = vertices.generate();
	// Do something with vertex
	vertices.next();
}

Once done() returns true, calling next() or generate() will throw std::out_of_bounds. There is no way to rewind the generator.

If the vertex/edge/triangle count needs to be known before iteration use the helper function count from util.hpp.

count(sphere.vertices());

Iterators

It is possible to use an iterator to drive a generator. Use free functions begin and end on the generator to get the iterators. If the generator is deleted the iterators are invalid.

SphereMesh sphere{};
auto vertices = sphere.vertices();
std::for_each(begin(vertices), end(vertices), [] (const MeshVertex& vertex) {
	// do something with vertex
});

for loops will also work.

SphereMesh sphere{};
for (const MeshVertex& vertex : sphere.vertices()) {
	// do something with vertex
}

NOTE: Be aware of a lifetime issue with a temporary primitive and the for loop.

for (const MeshVertex& vertex : SphereMesh{}.vertices()) {
	// Error! Undefined behaviour!
}

Modifiers

Some primitives such as TranslateMesh do not generate data of their own. Instead they modify data generated by another primitives. They are called "modifiers".

Modifiers store the primitive they modify.

TranslateMesh<SphereMesh> translatedSphere{SphereMesh{}, {1.0f, 0.0f, 0.0f}};
for (const auto& vertex : translatedSphere.vertices()) { }

Multiple modifiers can be nested.

Each modifier also has a function to make one. The function form has the same name as the class but starts with a lower case letter. translateMesh instead of TranslateMesh etc. This makes template argument deduction possible.

auto result = translateMesh(
	rotateMesh(
		scaleMesh(TorusMesh{}, {0.5f, 1.0f, 1.0}),
		gml::radians(90.0), Axis::Y
	),
	{1.0f, 0.0f, 0.0f}
);
for (const MeshVertex& vertex : result.vertices()) { }

Available modifiers for shapes are:

AxisSwapShape
FlipShape
MergeShape
RepeatShape
RotateShape
ScaleShape
SubdivideShape
TransformShape
TranslateShape

Available modifiers for paths are:

AxisSwapPath
FlipPath
MergePath
RepeatPath
RotatePath
ScalePath
SubdividePath
TransformPath
TranslatePath

Available modifiers for meshes are:

AxisSwapMesh
ExtrudeMesh
FlipMesh
LatheMesh
MergeMesh
RepeatMesh
RotateMesh
ScaleMesh
SpherifyMesh
SubdivideMesh
TransformMesh
TranslateMesh
UvSwapMesh

Preview and debug

For preview and debug purposes generator has class SvgWriter that can create SVG images of primitives.

It also has class ObjWriter that can write OBJ files of meshes that can be viewed with most 3d programs such as Blender.

And possibly other types as well. This is while using GLM. Currently investigating. Here's a stack trace.

Segfault when generating a BoxMesh

Infinite loop when generating IcosahedronMesh or IcoSphereMesh

This happens in my own code, but not in generate-glm. It could just be my own code, but I wanted to report this before I forget.

Looks like it's in the generation of Triangles.

Also may have something to do with an unsigned integer either not being initialized or over/underflowing.

Also, this is with GLM.

msvc 2015 x64 compilation issue

Hi,

we are trying to build your lib (with glm) on Windows with msvc 2015 (x64) and we have the following issue

How set are you on using your own math library?

I think GLM would be a better fit, personally, as it's similarly lightweight and more maintained. But if you'd like, I can compromise and let the user pick between GLM and GML at compile-time.

Issues with SphereMesh

Hello! I'm trying to use the sphere mesh and when looping over vertices, the first 32 positions are 0, 0, 1. This ends up generating something that looks kind of like an icecream cone. IcoSphereMesh works fine though. Have you seen this issue?

Fix some #include errors

You'd think someone would have made a library for something like this a long time ago. Well, I don't feel like writing my own, so you're stuck with me contributing to yours. Looks like I could get some use out of it!

Generate closed cylinder

Cylinder generation is made by sweeping. If a solid cylinder is generated, the algorithm creates overlapping points at the beginning and the end. This way, the surface is not a closed one... It's there a way to fix this? Thanks

Make GLM/GML compatibility layer in math.hpp more transparent

I.e. make it more idiot-proof while changing the existing generator code as little as possible, and not changing gml at all. Also, better document the addition of more GML substitutes.
