compute_frame()

void MayaFlux::Nodes::GpuSync::GeometryLeafNode::compute_frame ( )

overridevirtual

No-op unless a mutator has run since the last call, so AssemblyOperator::process() calling this on every item every frame stays cheap regardless of how many items exist.

Implements MayaFlux::Nodes::GpuSync::GpuSync.
