D3DXCreateVolumeTexture function

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

Syntax


HRESULT D3DXCreateVolumeTexture(
  _In_  LPDIRECT3DDEVICE9        pDevice,
  _In_  UINT                     Width,
  _In_  UINT                     Height,
  _In_  UINT                     Depth,
  _In_  UINT                     MipLevels,
  _In_  DWORD                    Usage,
  _In_  D3DFORMAT                Format,
  _In_  D3DPOOL                  Pool,
  _Out_ LPDIRECT3DVOLUMETEXTURE9 *ppVolumeTexture
);

Parameters

pDevice [in]

Type: LPDIRECT3DDEVICE9

Pointer to an IDirect3DDevice9 interface, representing the device to be associated with the volume texture.

Width [in]

Type: UINT

Width in pixels. This value must be nonzero. The maximum dimension that a driver supports (for width, height, and depth) can be found in MaxVolumeExtent in D3DCAPS9.

Height [in]

Type: UINT

Height in pixels. This value must be nonzero. The maximum dimension that a driver supports (for width, height, and depth) can be found in MaxVolumeExtent in D3DCAPS9.

Depth [in]

Type: UINT

Depth in pixels. This value must be nonzero. The maximum dimension that a driver supports (for width, height, and depth) can be found in MaxVolumeExtent in D3DCAPS9.

MipLevels [in]

Type: UINT

Number of mip levels requested. If this value is zero or D3DX_DEFAULT, a complete mipmap chain is created.

Usage [in]

Type: DWORD

0 or D3DUSAGE_DYNAMIC. For more information about using dynamic textures, see Using Dynamic Textures.

Format [in]

Type: D3DFORMAT

Member of the D3DFORMAT enumerated type, describing the requested pixel format for the volume texture. The returned volume texture might have a different format from that specified by Format. Applications should check the format of the returned volume texture.

Pool [in]

Type: D3DPOOL

Member of the D3DPOOL enumerated type, describing the memory class into which the volume texture should be placed.

ppVolumeTexture [out]

Type: LPDIRECT3DVOLUMETEXTURE9*

Address of a pointer to an IDirect3DVolumeTexture9 interface, representing the created volume 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, E_OUTOFMEMORY .

Remarks

Internally, D3DXCreateVolumeTexture uses D3DXCheckVolumeTextureRequirements to adjust the calling parameters. Therefore, calls to D3DXCreateVolumeTexture will often succeed where calls to CreateVolumeTexture would fail.

Requirements

D3dx9tex.h
