compute_frame()

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

overridevirtual

Compute GPU data for this frame.

Called once per VISUAL_RATE tick. Subclasses populate their respective buffers (pixel_buffer, vertex_buffer, readback_data).

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

Reimplemented in MayaFlux::Nodes::GpuSync::SDFNode.
