Detailed Description

template<typename GridT = Film::RGBA, typename SamplerType = tools::PointSampler>
class openvdb::v12_0::tools::DiffuseShader< GridT, SamplerType >

Simple diffuse Lambertian surface shader.

The diffuse color can either be constant (if GridT = Film::RGBA which is the default) or defined in a separate Vec3 color grid. Lambertian implies that the (radiant) intensity is directly proportional to the cosine of the angle between the surface normal and the direction of the light source. Use SamplerType to define the order of interpolation (default is zero order, i.e. closes-point).
