Renders geometry using the values of a field array as fragment colors.
The output can be used for deferred color mapping. It supports using arrays of either point or cell data. The target array can be selected by setting an array name/id and a component number. Only opaque geometry is supported.
There are two rendering modes available:
- INVERTIBLE_LUT Encodes array values as RGB data and renders the result to the default framebuffer. It uses a texture as a color LUT to map the values to RGB data. Texture size constraints limit its precision (currently 12-bit). The implementation of this mode is in vtkInternalsInvertible. This option is deprecated now that the SGI patent on floating point textures has expired and Mesa and other OpenGL's always supports it.
- FLOATING_POINT Renders actual array values as floating point data to an internal RGBA32F framebuffer. This class binds and unbinds the framebuffer on each render pass. Resources are allocated on demand. When rendering point data values are uploaded to the GPU as vertex attributes. When rendering cell data values are uploaded as a texture buffer. Custom vertex and fragment shaders are defined in order to adjust its behavior for either type of data.
