Description
This extension is based off the VK_AMD_draw_indirect_count extension.
This extension allows an application to source the number of draw calls
for indirect draw calls from a buffer.
Applications might want to do culling on the GPU via a compute shader prior to the draw. This enables the application to generate arbitrary amounts of draw commands and execute them without host intervention.
Promotion to Vulkan 1.2
All functionality in this extension is included in core Vulkan 1.2, with
the KHR suffix omitted. However, if Vulkan 1.2 is supported and this
extension is not, the entry points
cmdDrawIndirectCount
and
cmdDrawIndexedIndirectCount
are optional. The original type, enum and command names are still
available as aliases of the core functionality.
New Commands
New Enum Constants
