Detailed Description

template<typename GridT = Film::RGBA, typename SamplerType = tools::PointSampler>
class openvdb::v5_2::tools::PositionShader< GridT, SamplerType >

Color shader that treats position (x, y, z) as an RGB color in a cube defined from an axis-aligned bounding box in world space.

The color can either be constant (if GridT = Film::RGBA which is the default) or defined in a separate Vec3 color grid. Use SamplerType to define the order of interpolation (default is zero order, i.e. closes-point).
