This extension provides a new mechanism allowing applications to generate collections of geometric primitives via programmable mesh shading. It is an alternative to the existing programmable primitive shading pipeline, which relied on generating input primitives by a fixed function assembler as well as fixed function vertex fetch.

There are new programmable shader types — the task and mesh shader — to generate these collections to be processed by fixed-function primitive assembly and rasterization logic. When task and mesh shaders are dispatched, they replace the core pre-rasterization stages, including vertex array attribute fetching, vertex shader processing, tessellation, and geometry shader processing.

This extension also adds support for the following SPIR-V extension in Vulkan:

Method Summary

Modifier and TypeMethod and Description
public static void
vkCmdDrawMeshTasksIndirectCountNV(VkCommandBuffer
the command buffer into which the command is recorded.
commandBuffer, long
the buffer containing draw parameters.
buffer, long
the byte offset into buffer where parameters begin.
offset, long
the buffer containing the draw count.
countBuffer, long
the byte offset into countBuffer where the draw count begins.
countBufferOffset, int
specifies the maximum number of draws that will be executed. The actual number of executed draw calls is the minimum of the count specified in countBuffer and maxDrawCount.
maxDrawCount, int
the byte stride between successive sets of draw parameters.
stride)

Perform an indirect mesh tasks draw with the draw count sourced from a buffer.

public static void
vkCmdDrawMeshTasksIndirectNV(VkCommandBuffer
the command buffer into which the command is recorded.
commandBuffer, long
the buffer containing draw parameters.
buffer, long
the byte offset into buffer where parameters begin.
offset, int
the number of draws to execute, and can be zero.
drawCount, int
the byte stride between successive sets of draw parameters.
stride)

Issue an indirect mesh tasks draw into a command buffer.

public static void
vkCmdDrawMeshTasksNV(VkCommandBuffer
the command buffer into which the command will be recorded.
commandBuffer, int
the number of local workgroups to dispatch in the X dimension. Y and Z dimension are implicitly set to one.
taskCount, int
the X component of the first workgroup ID.
firstTask)

Draw mesh task work items.
