D3DXFillCubeTexture Function

Uses a user-provided function to fill each texel of each mip level of a given cube texture.

Syntax

HRESULT D3DXFillCubeTexture(      

    LPDIRECT3DCUBETEXTURE9 pTexture,
    LPD3DXFILL3D pFunction,
    LPVOID pData
);

Parameters

pTexture

[out, retval] Pointer to an IDirect3DCubeTexture9 interface, representing the filled texture.

pFunction

[in] Pointer to a user-provided evaluator function, which will be used to compute the value of each texel. The function follows the prototype of LPD3DFILL3D.

pData

[in] Pointer to an arbitrary block of user-defined data. This pointer will be passed to the function provided in pFunction.

Return Value

If the function succeeds, the return value is D3D_OK.

If the function fails, the return value can be one of the following values.

D3DERR_INVALIDCALL

The method call is invalid. For example, a method's parameter may have an invalid value.

Remarks

Here is an example that creates a function called ColorCubeFill, which relies on D3DXFillCubeTexture.

// Define a function that matches the prototype of LPD3DXFILL3D
VOID WINAPI ColorCubeFill (D3DXVECTOR4* pOut, const D3DXVECTOR3* pTexCoord, 
const D3DXVECTOR3* pTexelSize, LPVOID pData)
{
   *pOut = D3DXVECTOR4(pTexCoord->x, pTexCoord->y, pTexCoord->z, 0.0f);
}


// Create volume texture using D3DXFillCubeTexture
if (FAILED (hr = D3DXFillCubeTexture (m_pTexture, ColorCubeFill, NULL)))
{
       return hr;
}
