“Design Patterns for Low-Level Real-Time Rendering”
summary
New GPU APIs like Vulkan Direct3D 12 and Metal give fine control but add complexity; the talk claims patterns that cut that complexity by an order of magnitude while improving performance. Concrete techniques: a DirectX 12 ray tracer prototype, ring buffer streaming returning CPU and GPU addresses, descriptor streaming, fences for GPU/CPU sync, parallel command recording with fork/join and hyperobject merging, and a frame graph scheduler that inserts barriers, reuses memory and elides dead passes.
