Detailed Description

The RadixSortGPU requires calling a setup function once during initialization, after which the sort can be invoked as needed.

Direct radix sort: Use when the number of elements to sort is known on the CPU. Creates a draw indirect buffer internally with the element count, then uses the same shader pipeline as the indirect version. No indirect buffer needed but requires CPU knowledge of the sort size.

void GR_Utils::RadixSortGPU::setupRadixSortGPUIndirect	(	RV_Render *	rv,
		UT_UniquePtr< RV_ShaderBlock > &	draw_indirect_params,
		RV_VKBuffer *	keys_buffer,
		RV_VKBuffer *	indices_buffer
	)

Indirect radix sort: Use when the number of elements to sort is determined dynamically on the GPU (e.g., after GPU frustum culling). Takes a draw indirect buffer from a previous GPU pass, keeping all data on the GPU without CPU readback. The indirect buffer's instance count determines how many elements to sort.
