Description

If the PhysicalDeviceMeshShaderFeaturesNV structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with a value indicating whether the feature is supported. PhysicalDeviceMeshShaderFeaturesNV can also be included in pNext chain of DeviceCreateInfo to enable the features.

Valid Usage (Implicit)

Members

The members of the PhysicalDeviceMeshShaderPropertiesNV structure describe the following implementation-dependent limits:

PhysicalDeviceMeshShaderFeaturesNV
Fields taskShader :: Bool `taskShader` indicates whether the task shader stage is supported. meshShader :: Bool `meshShader` indicates whether the mesh shader stage is supported.

DrawMeshTasksIndirectCommandNV
Fields taskCount :: Word32 `taskCount` is the number of local workgroups to dispatch in the X dimension. Y and Z dimension are implicitly set to one. `taskCount` must be less than or equal to `PhysicalDeviceMeshShaderPropertiesNV`::`maxDrawMeshTasksCount` firstTask :: Word32 `firstTask` is the X component of the first workgroup ID.
