processing_function()

void MayaFlux::Buffers::VolumeFieldProcessor::processing_function ( const std::shared_ptr< Buffer > &  buffer )

overrideprotectedvirtual

Rewrite field descriptors, run the shader, then swap.

Parameters

buffer

Buffer under processing.

Read slots change whenever an upstream stage swaps, so the bindings are rewritten every cycle rather than once.

Reimplemented from MayaFlux::Buffers::ShaderProcessor.
