processing_function()

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

overridevirtual

Executes the render callback.

Parameters

buffer

Buffer to process (must be RootGraphicsBuffer)

Validates buffer type and invokes the render callback. This is the core rendering coordination point - all child buffers have been processed by the time this executes.

Implements MayaFlux::Buffers::BufferProcessor.
