Architecting dynamic vertex streaming in WebGPU using storage buffers. Covers minimal design, memory boundaries, and strategies to avoid CPU‑GPU synchronization stalls.
For per-frame dynamic vertex buffer updates where the CPU must write geometry each iteration without introducing stalls, two documented OpenGL approaches compete: buffer orphaning via glBufferData(GL_STREAM_DRAW) and persistent mapping via glMapBufferRange with GL_MAP_UNSYNCHRONIZED_BIT . Buffer orphaning supplies a new data pointer each frame, enabling the
