ID3DXPatchMesh::GetDisplaceParam Method

Gets mesh geometry displacement parameters.

Syntax

HRESULT GetDisplaceParam(      

    LPDIRECT3DBASETEXTURE9* Texture,
    D3DTEXTUREFILTERTYPE* MinFilter,
    D3DTEXTUREFILTERTYPE* MagFilter,
    D3DTEXTUREFILTERTYPE* MipFilter,
    D3DTEXTUREADDRESS* Wrap,
    DWORD* dwLODBias
);

Parameters

Texture

[in] Texture containing the displacement data.

MinFilter

[in] Minification level. For more information, see D3DTEXTUREFILTERTYPE.

MagFilter

[in] Magnification level. For more information, see D3DTEXTUREFILTERTYPE.

MipFilter

[in] Mip filter level. For more information, see D3DTEXTUREFILTERTYPE.

Wrap

[in] Texture address wrap mode. For more information, see D3DTEXTUREADDRESS.

dwLODBias

[in] Level of detail bias value.

Return Value

If the method succeeds, the return value is D3D_OK.

If the method 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.
E_OUTOFMEMORY	Microsoft?Direct3D?could not allocate sufficient memory to complete the call.

Remarks

Displacement maps can only be 2-D textures. Mipmapping is ignored for nonadaptive tessellation.
