s |
[in] The sampler state. |
t |
[in] The texture coordinate. |
ddx |
[in] Rate of change of the surface geometry in the x direction. |
ddy |
[in] Rate of change of the surface geometry in the y direction. |
The value of the texture data.

This function is supported in the following shader models.
Shader Model | Supported |
---|---|
Shader Model 4 | yes (pixel shader only) |
Shader Model 3 (DirectX HLSL) | yes (pixel shader only) |
Shader Model 2 (DirectX HLSL) | yes (pixel shader only) |
Shader Model 1 (DirectX HLSL) | no |
- Significant code reordering is done to move gradient computations outside of flow control.
- If the D3DPSHADERCAPS2_0 cap is set with D3DD3DPSHADERCAPS2_0_GRADIENTINSTRUCTIONS, the compiler maps this function to texldd.
