Syntax

HRESULT GetDisplaceParam(
  [in] LPDIRECT3DBASETEXTURE9 *Texture,
  [in] D3DTEXTUREFILTERTYPE   *MinFilter,
  [in] D3DTEXTUREFILTERTYPE   *MagFilter,
  [in] D3DTEXTUREFILTERTYPE   *MipFilter,
  [in] D3DTEXTUREADDRESS      *Wrap,
  [in] DWORD                  *dwLODBias
);

Parameters

Texture [in]

Type: LPDIRECT3DBASETEXTURE9*

Texture containing the displacement data.

MinFilter [in]

Type: D3DTEXTUREFILTERTYPE*

Minification level. For more information, see D3DTEXTUREFILTERTYPE.

MagFilter [in]

Type: D3DTEXTUREFILTERTYPE*

Magnification level. For more information, see D3DTEXTUREFILTERTYPE.

MipFilter [in]

Type: D3DTEXTUREFILTERTYPE*

Mip filter level. For more information, see D3DTEXTUREFILTERTYPE.

Wrap [in]

Type: D3DTEXTUREADDRESS*

Texture address wrap mode. For more information, see D3DTEXTUREADDRESS.

dwLODBias [in]

Type: DWORD*

Level of detail bias value.

Return value

Type: HRESULT

If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be one of the following: D3DERR_INVALIDCALL, E_OUTOFMEMORY.

Remarks
