LLGL::DrawPatchIndirectArguments Struct Reference

Structure for the arguments of an indirect draw/indexed-draw command for tessellation on Metal renderer. More...

#include <IndirectArguments.h>

Public Attributes
std::uint32_t	numPatches
	Specifies the number of patches per instance.
std::uint32_t	numInstances
	Specifies the number of instances to draw.
std::uint32_t	firstPatch
	Specifies the patch start index.
std::uint32_t	firstInstance
	Specifies the first instance to draw.

Detailed Description

Structure for the arguments of an indirect draw/indexed-draw command for tessellation on Metal renderer.

Remarks

This is a plain-old-data (POD) structure aligned with no default constructor to make it compatible between CPU and GPU memory space.

The Metal API treats the arguments for rendering tessellated patches differently, so this structure is required to fill the buffer that is used for the arguments of an indirect draw command on the Metal backend.

Note

Only supported with: Metal.
