VkDrawMeshTasksIndirectCommandEXT(3)

Name

VkDrawMeshTasksIndirectCommandEXT - Structure specifying a mesh tasks draw indirect command

C Specification

The VkDrawMeshTasksIndirectCommandEXT structure is defined as:

// Provided by VK_EXT_mesh_shader
typedef struct VkDrawMeshTasksIndirectCommandEXT {
    uint32_t    groupCountX;
    uint32_t    groupCountY;
    uint32_t    groupCountZ;
} VkDrawMeshTasksIndirectCommandEXT;

Members

  • groupCountX is the number of local workgroups to dispatch in the X dimension.

  • groupCountY is the number of local workgroups to dispatch in the Y dimension.

  • groupCountZ is the number of local workgroups to dispatch in the Z dimension.

Description

The members of VkDrawMeshTasksIndirectCommandEXT have the same meaning as the similarly named parameters of vkCmdDrawMeshTasksEXT.

Valid Usage

  • VUID-VkDrawMeshTasksIndirectCommandEXT-TaskEXT-07322
    If the current pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS contains a shader using the TaskEXT Execution Model, groupCountX must be less than or equal to VkPhysicalDeviceMeshShaderPropertiesEXT::maxTaskWorkGroupCount[0]

  • VUID-VkDrawMeshTasksIndirectCommandEXT-TaskEXT-07323
    If the current pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS contains a shader using the TaskEXT Execution Model, groupCountY must be less than or equal to VkPhysicalDeviceMeshShaderPropertiesEXT::maxTaskWorkGroupCount[1]

  • VUID-VkDrawMeshTasksIndirectCommandEXT-TaskEXT-07324
    If the current pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS contains a shader using the TaskEXT Execution Model, groupCountZ must be less than or equal to VkPhysicalDeviceMeshShaderPropertiesEXT::maxTaskWorkGroupCount[2]

  • VUID-VkDrawMeshTasksIndirectCommandEXT-TaskEXT-07325
    If the current pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS contains a shader using the TaskEXT Execution Model, The product of groupCountX, groupCountY and groupCountZ must be less than or equal to VkPhysicalDeviceMeshShaderPropertiesEXT::maxTaskWorkGroupTotalCount

  • VUID-VkDrawMeshTasksIndirectCommandEXT-TaskEXT-07326
    If the current pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS does not contain a shader using the TaskEXT Execution Model, groupCountX must be less than or equal to VkPhysicalDeviceMeshShaderPropertiesEXT::maxMeshWorkGroupCount[0]

  • VUID-VkDrawMeshTasksIndirectCommandEXT-TaskEXT-07327
    If the current pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS does not contain a shader using the TaskEXT Execution Model, groupCountY must be less than or equal to VkPhysicalDeviceMeshShaderPropertiesEXT::maxMeshWorkGroupCount[1]

  • VUID-VkDrawMeshTasksIndirectCommandEXT-TaskEXT-07328
    If the current pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS does not contain a shader using the TaskEXT Execution Model, groupCountZ must be less than or equal to VkPhysicalDeviceMeshShaderPropertiesEXT::maxMeshWorkGroupCount[2]

  • VUID-VkDrawMeshTasksIndirectCommandEXT-TaskEXT-07329
    If the current pipeline bound to VK_PIPELINE_BIND_POINT_GRAPHICS does not contain a shader using the TaskEXT Execution Model, The product of groupCountX, groupCountY and groupCountZ must be less than or equal to VkPhysicalDeviceMeshShaderPropertiesEXT::maxMeshWorkGroupTotalCount
