Windows Driver Kit DDI reference (ns-d3d12umddi-d3d12ddiarg_mesh_io_signatures)

Description

The D3D12DDIARG_MESH_IO_SIGNATURES structure describes a set of signatures for a given mesh shader's output primitives and vertices.

Members

`pPrimitiveOutputSignature`

An array of signatures; namely, the set of all registers affected by primitives output by the mesh shader.

`NumPrimitiveOutputSignatureEntries`

Size, in elements, of the pPrimitiveOutputSignature array.

`pVertexOutputSignature`

An array of signatures; namely, the union of all registers affected by vertices output by the mesh shader.

`NumVertexOutputSignatureEntries`

Size, in elements, of the pVertexOutputSignature array.

Remarks

This information is passed to the driver on creation of a mesh shader.

See the Mesh Shader Specification for more information.
