setup_rendering()

void MayaFlux::Buffers::VolumeGridBuffer::setup_rendering

(

const RenderConfig &

config

)

Attach a RenderProcessor drawing the extracted surface.

Parameters

config

Render target. Vertex and fragment shaders default to the untextured triangle pair; topology is forced to TRIANGLE_LIST.

Requires a SurfaceConfig at construction. Without one this buffer has no vertex storage and nothing to draw.
