IDirect3DDevice8::SetPixelShaderConstant

Sets the values in the pixel constant array.

HRESULT SetPixelShaderConstant(
  DWORD Register,
  CONST void* pConstantData,
  DWORD ConstantCount
);

Parameters

Register: [in] Register address at which to start loading data into the pixel constant array.
pConstantData: [in] Pointer to the data block holding the values to load into the pixel constant array. The size of the data block is (ConstantCount * 4 * sizeof(float)).
ConstantCount: [in] Number of constants to load into the pixel constant array. Each constant is comprised of four floating-point values.

Return Values

If the method succeeds, the return value is D3D_OK.

If the method fails, the return value can be D3DERR_INVALIDCALL.

Remarks

This is the method used to load the constant registers of the pixel shader assembler.

Requirements

Header: Declared in D3d8.h.
Import Library: Use D3d8.lib.
