vkCmdDrawMeshTasksIndirectNV - Issue an indirect mesh tasks draw into a command buffer

Description

cmdDrawMeshTasksIndirectNV behaves similarly to cmdDrawMeshTasksNV except that the parameters are read by the device from a buffer during execution. drawCount draws are executed by the command, with parameters taken from buffer starting at offset and increasing by stride bytes for each successive draw. The parameters of each draw are encoded in an array of DrawMeshTasksIndirectCommandNV structures. If drawCount is less than or equal to one, stride is ignored.

• maxDrawMeshTasksCount :: Word32

  maxDrawMeshTasksCount is the maximum number of local workgroups that can be launched by a single draw mesh tasks command. See https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#drawing-mesh-shading.

• maxTaskWorkGroupInvocations :: Word32

  maxTaskWorkGroupInvocations is the maximum total number of task shader invocations in a single local workgroup. The product of the X, Y, and Z sizes, as specified by the LocalSize execution mode in shader modules or by the object decorated by the WorkgroupSize decoration, must be less than or equal to this limit.

  maxMeshOutputPrimitives is the maximum number of primitives a mesh shader output can store.

• maxMeshMultiviewViewCount :: Word32

  maxMeshMultiviewViewCount is the maximum number of multi-view views a mesh shader can use.

• meshOutputPerVertexGranularity :: Word32

  meshOutputPerVertexGranularity is the granularity with which mesh vertex outputs are allocated. The value can be used to compute the memory size used by the mesh shader, which must be less than or equal to maxMeshTotalMemorySize.

• meshOutputPerPrimitiveGranularity :: Word32

  meshOutputPerPrimitiveGranularity is the granularity with which mesh outputs qualified as per-primitive are allocated. The value can be used to compute the memory size used by the mesh shader, which must be less than or equal to maxMeshTotalMemorySize.
