push_constants() [2/2]

void MayaFlux::Portal::Graphics::ComputePress::push_constants	(	CommandBufferID	cmd_id,
		ComputePipelineID	pipeline_id,
		const void *	data,
		size_t	size,
		uint32_t	offset
	)

Push part of the push constant block, starting at a byte offset.

Parameters

offset

Byte offset into the block

The range [offset, offset + size) must lie inside the push constant size the pipeline was created with; otherwise nothing is recorded.
