Declares the primitive type geometry-shader output data.

dcl_outputTopology type
Item Description
type
 [in] An output primitive topology, which is one of the following values:
  • pointlist
  • linestrip
  • trianglestrip

This instruction applies to the following shader stages:

Vertex Shader Geometry Shader Pixel Shader
x

This instruction is included to aid in debugging a shader in assembly; you cannot author a shader in assembly language using Shader Model 4.

Example

Here is an example.
