PFND3DDDI_SETPIXELSHADER callback function

Description

The SetPixelShader function sets a pixel shader to be used in all drawing operations.

Parameters

`hDevice`

A handle to the display device (graphics context).

`unnamedParam2`

hShaderHandle [in]

A handle to the pixel shader code object.

Return value

SetPixelShader returns S_OK or an appropriate error result if the pixel shader is not successfully set.

Remarks

All subsequent drawing operations use the given shader until another is selected.

For user-mode display drivers that support pixel shaders before version 2.0, the Microsoft Direct3D runtime passes 0 in the hShaderHandle parameter to indicate a fixed-function pipeline. For user-mode display drivers that support pixel shader version 2.0 or later, the runtime converts Direct3D fixed-function pixel state to pixel shader version 2.0. For more information about fixed-function state, see Converting the Direct3D Fixed-Function State.
