GpuCommandEncoder¶
Import: import system.gpu;
This reference lists the public declarations for this part of the library. See Reading API signatures for parameter and result notation. Shader-only declarations can be used only inside @compute, @vertex, @fragment, inferred helpers and ray tracing shader functions; using them elsewhere is a compile error.
GpuCommandEncoder¶
Records GPU work, such as render passes, compute passes and copies, to submit together. Get one from GpuDevice.command_encoder or a window frame's GpuFrame.encoder. Passes run in the order they were begun; end each pass before beginning the next. Mistakes such as a resource from another device do not fail immediately: the first one is returned by GpuDevice.submit.
begin_render_pass¶
Begins drawing into the targets of desc. End the pass with GpuRenderPass.end.
begin_compute_pass¶
Begins a compute pass. Record dispatches into it with the generated GpuShaders.<name>.encode, then end it with GpuComputePass.end.
copy_buffer¶
Copies count elements from source, starting at element source_offset, into destination starting at destination_offset. Both ranges must lie inside their buffers. Record copies outside passes.
public fun copy_buffer<T: unmanaged>(
source: GpuBuffer<T>,
source_offset: int,
destination: GpuBuffer<T>,
destination_offset: int,
count: int
): void
finish¶
Ends recording. Pass the result to GpuDevice.submit.
