| #define | GPU_storagebuf_create(size) |
Storage buffers API. Used to handle many way bigger buffers than Uniform buffers update at once. Make sure that the data structure is compatible with what the implementation expect. (see "7.8 Shader Buffer Variables and Shader Storage Blocks" from the OpenGL spec for more info about std430 layout) Rule of thumb: Padding to 16bytes, don't use vec3.

| void GPU_storagebuf_read | ( | blender::gpu::StorageBuf * | ssbo, |
| void * | data ) |
Read back content of the buffer to CPU for inspection. Slow! Only use for inspection / debugging.
NOTE: If GPU_storagebuf_sync_to_host is called, this command is synchronized against that call. If pending GPU updates to the storage buffer are not yet visible to the host, the command will stall until dependent GPU work has completed.
Otherwise, this command is synchronized against this call and will stall the CPU until the buffer content can be read by the host.
