    Member documentation

    • sType – the type of this structure.
    • pNextNULL or a pointer to an extension-specific structure.
    • maxDrawMeshTasksCount – the maximum number of local workgroups that can be launched by a single draw mesh tasks command. See Programmable Mesh Shading.
    • maxTaskWorkGroupInvocations – 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.
    • maxTaskWorkGroupSize[3] – the maximum size of a local task workgroup. These three values represent the maximum local workgroup size in the X, Y, and Z dimensions, respectively. The x, y, and z sizes, as specified by the LocalSize execution mode or by the object decorated by the WorkgroupSize decoration in shader modules, must be less than or equal to the corresponding limit.
    • maxTaskTotalMemorySize – the maximum number of bytes that the task shader can use in total for shared and output memory combined.
    • maxTaskOutputCount – the maximum number of output tasks a single task shader workgroup can emit.
    • maxMeshWorkGroupInvocations – the maximum total number of mesh 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.
    • maxMeshWorkGroupSize[3] – the maximum size of a local mesh workgroup. These three values represent the maximum local workgroup size in the X, Y, and Z dimensions, respectively. The x, y, and z sizes, as specified by the LocalSize execution mode or by the object decorated by the WorkgroupSize decoration in shader modules, must be less than or equal to the corresponding limit.
    • maxMeshTotalMemorySize – the maximum number of bytes that the mesh shader can use in total for shared and output memory combined.
    • maxMeshOutputVertices – the maximum number of vertices a mesh shader output can store.
    • maxMeshOutputPrimitives – the maximum number of primitives a mesh shader output can store.
    • maxMeshMultiviewViewCount – the maximum number of multi-view views a mesh shader can use.
    • meshOutputPerVertexGranularity – 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 – 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.

        public VkPhysicalDeviceMeshShaderPropertiesNV​(java.nio.ByteBuffer container)
        Creates a VkPhysicalDeviceMeshShaderPropertiesNV instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.
