dcl_output oDepth (sm4 - asm)
Declares that a pixel shader will use the output-depth register.
| dcl_output oDepth |
|---|
The value in the output-depth register is used during a depth comparison (if depth compare is enabled).
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 are some examples.
