Project that converts pbrt scene files into c++ classes => can be used to write an exporter to another scene format.

The project is configured as a console application that takes an input pbrt file, the output destination and some optional parameters. See Source/main.cpp for the description of all optional parameters.

To convert the PBRT c++ class to you own format, replace the // TODO convert to your own scene format here in main() with your converter.

The most important PBRT c++ classes are:

• PbrtScene was used to build the Scene. Call getRenderOptions() to get the scene configuation.
• RenderOptions:

struct RenderOptions
{
  Matrix cameraToWorld;
  SceneObject camera;
  Vector cameraPos;
  Vector cameraLookAt;
  SceneObject sampler;
  SceneObject film;
  SceneObject renderer;
  SceneObject surfaceIntegrator;
  SceneObject volumeIntegrator;
  SceneObject accelerator;
  SceneObject pixelFilter;
  std::vector<SceneObject> volumeRegions;
  std::vector<std::unique_ptr<Shape>> shapes;
  std::vector<Light> lights;
};

• SceneObject. Used to describe the Camera, Renderer etc.

	struct SceneObject
	{
		std::string type;
		ParamSet set;
	};

• ParamSet Dictionary to look up parameters. Example: If the Camera SceneObject has the type "perspective", you can use camera.set.getFloat("fov", 90.0f) to retrieve the fov. If the parameter was not set, 90.0f will be returned.

• Shape: base class for all shapes. Implemented shapes are: Triangle and Sphere

• Light

• Material
