D3DXCreateCubeTexture Function


Creates an empty cube texture, adjusting the calling parameters as needed.

Syntax

HRESULT D3DXCreateCubeTexture(      

    LPDIRECT3DDEVICE9 pDevice,     UINT Size,     UINT MipLevels,     DWORD Usage,     D3DFORMAT Format,     D3DPOOL Pool,     LPDIRECT3DCUBETEXTURE9 *ppCubeTexture );

Parameters

pDevice
[in] Pointer to an IDirect3DDevice9 interface, representing the device to be associated with the texture.
Size
[in] Width and height of the cube texture, in pixels. For example, if the cube texture is an 8-pixel by 8-pixel cube, the value for this parameter should be 8.
MipLevels
[in] Number of mip levels requested. If this value is zero or D3DX_DEFAULT, a complete mipmap chain is created.
Usage
[in] 0, D3DUSAGE_RENDERTARGET, or D3DUSAGE_DYNAMIC. Setting this flag to D3DUSAGE_RENDERTARGET indicates that the surface is to be used as a render target. The resource can then be passed to the pNewRenderTarget parameter of the IDirect3DDevice9::SetRenderTarget method. If D3DUSAGE_RENDERTARGET is specified, the application should check that the device supports this operation by calling IDirect3D9::CheckDeviceFormat. For more information about using dynamic textures, see Using Dynamic Textures.
Format
[in] Member of the D3DFORMAT enumerated type, describing the requested pixel format for the cube texture. The returned cube texture might have a different format from that specified by Format. Applications should check the format of the returned cube texture.
Pool
[in] Member of the D3DPOOL enumerated type, describing the memory class into which the cube texture should be placed.
ppCubeTexture
[out] Address of a pointer to an IDirect3DCubeTexture9 interface, representing the created cube texture object.

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_INVALIDCALLThe method call is invalid. For example, a method's parameter may have an invalid value.
D3DERR_NOTAVAILABLEThis device does not support the queried technique.
D3DERR_OUTOFVIDEOMEMORYMicrosoft?Direct3D?does not have enough display memory to perform the operation.
E_OUTOFMEMORYDirect3D could not allocate sufficient memory to complete the call.


Remarks

Cube textures differ from other surfaces in that they are collections of surfaces.

Internally, D3DXCreateCubeTexture uses D3DXCheckCubeTextureRequirements to adjust the calling parameters. Therefore, calls to D3DXCreateCubeTexture will often succeed where calls to IDirect3DDevice9::CreateCubeTexture would fail.
