| === Description |
| |
| This extension is based off the `apiext:VK_AMD_draw_indirect_count` |
| extension. |
| This extension allows an application to source the number of draws for |
| indirect draw calls from a buffer. |
| |
| Applications might want to do culling on the GPU via a compute shader prior |
| to drawing. |
| This enables the application to generate an arbitrary number of drawing |
| 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 flink:vkCmdDrawIndirectCount and flink:vkCmdDrawIndexedIndirectCount |
| are optional. |
| The original type, enum and command names are still available as aliases of |
| the core functionality. |
