compute_frame()

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

overridevirtual

Pack accumulated segments into the GPU vertex buffer.

Bypasses all PathGeneratorNode interpolation. Copies m_segments directly via set_vertices<LineVertex>.

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