Classes
class	LevelSetRayTracer< GridT, IntersectorT >
	A (very) simple multithreaded ray tracer specifically for narrow-band level sets. More...
class	Film
	A simple class that allows for concurrent writes to pixels in an image, background initialization of the image, and PPM or EXR file output. More...
struct	Film::RGBA
	Floating-point RGBA components in the range [0, 1]. More...
class	BaseCamera
	Abstract base class for the perspective and orthographic cameras. More...
class	PerspectiveCamera
class	OrthographicCamera
class	BaseShader
	Abstract base class for the shaders. More...
class	MatteShader
	Shader that produces a simple matte. More...
class	NormalShader
	Color shader that treats the surface normal (x, y, z) as an RGB color. More...
class	PositionShader
class	DiffuseShader
	Simple diffuse Lambertian surface shader. More...

Functions
template<typename GridT >

Note

These classes are included mainly to illustrate how to ray-trace OpenVDB volumes. They are not intended for production-quality rendering.
