POP Networks

GPU-accelerated point operations. POPs replace SOPs for 3D geometry with massively parallel GPU compute. See reference.md for operator decision tree and attribute reference.

Core Concepts

• Points with attributes: P (position), N (normal), Color, Tex, custom
• GPU-resident: all data stays on GPU, downloading to CPU causes stalls
• Memory model: unmodified input attributes pass by reference (zero-copy)
• Points alone don't render — need Point Primitives (set Connectivity on generators)
• Rendering: POPs in geometryCOMPs, rendered by renderTOP. MATs read POP attributes
• Data sourcing: POPs can exist in any COMP (baseCOMP, etc.) for data extraction without rendering
• GPU→CPU cost: poptoCHOP and poptoDAT copy data from GPU to CPU — can be heavy for large point counts
