setup_rendering()

void MayaFlux::Buffers::NodeTextureBuffer::setup_rendering

(

const RenderConfig &

config

)

Setup rendering with RenderProcessor.

Parameters

config

Rendering configuration

Configures the buffer for direct rendering to screen. The GPU texture will be bound and drawn automatically.
