RequiresChunkedRendering()

virtual bool VAPoR::VolumeAlgorithm::RequiresChunkedRendering ( )

pure virtual

On OSX, some shaders can run for a long time without problems while others will crash if the run too long. It seems to correlate with complexity. Chunked rendering splits the rendering into smaller tasks so they won't crash

Implemented in VAPoR::VolumeAlgorithmNull, VAPoR::VolumeCellTraversal, and VAPoR::VolumeRegular.

SaveDepthBuffer()

virtual void VAPoR::VolumeAlgorithm::SaveDepthBuffer ( bool  fast )

inlinevirtual

Reimplemented in VAPoR::VolumeGLSL.
