D3DXCreateVolumeTextureFromFile function
Creates a volume texture from a file.
Syntax
HRESULT D3DXCreateVolumeTextureFromFile(
_In_ LPDIRECT3DDEVICE9 pDevice,
_In_ LPCTSTR pSrcFile,
_Out_ LPDIRECT3DVOLUMETEXTURE9 *ppVolumeTexture
);
Parameters
-
pDevice [in]
-
Type: LPDIRECT3DDEVICE9
Pointer to an IDirect3DDevice9 interface, representing the device to be associated with the volume texture.
-
pSrcFile [in]
-
Type: LPCTSTR
Pointer to a string that specifies the file name. If the compiler settings require Unicode, the data type LPCTSTR resolves to LPCWSTR. Otherwise, the string data type resolves to LPCSTR. See Remarks.
-
ppVolumeTexture [out]
-
Type: LPDIRECT3DVOLUMETEXTURE9*
Address of a pointer to an IDirect3DVolumeTexture9 interface representing the created texture object.
Return value
Type: HRESULT
If the function succeeds, the return value is D3D_OK. If the function fails, the return value can be one of the following: D3DERR_NOTAVAILABLE, D3DERR_OUTOFVIDEOMEMORY, D3DERR_INVALIDCALL, D3DXERR_INVALIDDATA, E_OUTOFMEMORY.
Remarks
The compiler setting also determines the function version. If Unicode is defined, the function call resolves to D3DXCreateVolumeTextureFromFileW. Otherwise, the function call resolves to D3DXCreateVolumeTextureFromFileA because ANSI strings are being used.
The function is equivalent to D3DXCreateVolumeTextureFromFileEx(pDevice, pSrcFile, D3DX_DEFAULT, D3DX_DEFAULT, D3DX_DEFAULT, D3DX_DEFAULT, 0, D3DFMT_UNKNOWN, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, 0, NULL, NULL, ppVolumeTexture).
This function supports the following file formats: .bmp, .dds, .dib, .hdr, .jpg, .pfm, .png, .ppm, and .tga. See D3DXIMAGE_FILEFORMAT.
Mipmapped textures automatically have each level filled with the loaded texture.
When loading images into mipmapped textures, some devices are unable to go to a 1x1 image and this function will fail. If this happens, then the images need to be loaded manually.
Note that a resource created with this function when called from a IDirect3DDevice9 object will be placed in the memory class denoted by D3DPOOL_MANAGED. When this method is called from a IDirect3DDevice9Ex object the resource will be placed in the memory class denoted by D3DPOOL_DEFAULT.
Filtering is automatically applied to a texture created using this method. The filtering is equivalent to D3DX_FILTER_TRIANGLE | D3DX_FILTER_DITHER in D3DX_FILTER.
