dispatch_2d()

void MayaFlux::Core::VKComputePipeline::dispatch_2d	(	vk::CommandBuffer	cmd,
		uint32_t	width_elements,
		uint32_t	height_elements,
		uint32_t	local_size_x,
		uint32_t	local_size_y
	)		const

Dispatch compute workgroups in 2D with automatic calculation.

Parameters

cmd	Command buffer
width_elements	Width in elements
height_elements	Height in elements
local_size_x	Workgroup width (shader local_size_x)
local_size_y	Workgroup height (shader local_size_y)

Convenience for 2D operations (image processing, etc.)

Example: // Process 1920x1080 image with 16x16 workgroups pipeline.dispatch_2d(cmd, 1920, 1080, 16, 16);
