Procedural generation library

3D graphics procedural generation library based on Urho3D.

Build

Download Urho3D library, install it and make a Urho3D project.

Configure

cd build
cmake ..

Compile

cd build
make

Run

cd bin
./ProcGen

Modules

ProcGen

ProcGen is the basic module used by Voxels, Simulation and Maze modules. ProcGen module depends on libtcod for noise, heightmap and BSP generation.

Models

Basic component for creation and manipulation of procedural geometry.

ProcModel

GeometryCreator

ModelCreator

Materials

Techniques

Urho3D uses Technique to specify render passes and shaders used when rendering materials. Custom techniques are in CoreData/Techniques/ and are prefixed with Tec_.

Shaders

Custom shaders are in CoreData/Shaders/GLSL and are prefixed with Sha_.

When you write shaders, you can #include

• Transform2D.glsl to transform 2D points in the shader,
• Shapes2D.glsl to draw basic shapes in the shader; see PPE_Shapes.glsl for the shape drawing examples,

Postprocessing effects

Custom post processing effects are in CoreData/Shaders/GLSL and are prefixed with PPE_.

Textures

Use TextureCreator::CreateEffectTexture(int w, int h, const String& shader, RenderSurfaceUpdateMode mode) with "PPE_<effect_name>" as shader to create a texture based on a post process effect.

The easiest way to display a texture is to draw it in the UI as an Urho3D Sprite.

You can also display a texture by creating material with MaterialCreator::Create(const String& technique, const HashMap<TextureUnit, Texture*>& textureData) that uses a technique that displays a diffuse map. Use ModelCreator::CreateStockModel(const String& modelName, Material* material) to create a model using .mdl files from Data/Models.
