D3DXCreateSphere function
Uses a left-handed coordinate system to create a mesh containing a sphere.
Syntax
HRESULT D3DXCreateSphere(
_In_ LPDIRECT3DDEVICE9 pDevice,
_In_ FLOAT Radius,
_In_ UINT Slices,
_In_ UINT Stacks,
_Out_ LPD3DXMESH *ppMesh,
_Out_ LPD3DXBUFFER *ppAdjacency
);
Parameters
-
pDevice [in]
-
Type: LPDIRECT3DDEVICE9
Pointer to an IDirect3DDevice9 interface, representing the device associated with the created sphere mesh.
-
Radius [in]
-
Type: FLOAT
Radius of the sphere. This value should be greater than or equal to 0.0f.
-
Slices [in]
-
Type: UINT
Number of slices about the main axis.
-
Stacks [in]
-
Type: UINT
Number of stacks along the main axis.
-
ppMesh [out]
-
Type: LPD3DXMESH*
Address of a pointer to the output shape, an ID3DXMesh interface.
-
ppAdjacency [out]
-
Type: LPD3DXBUFFER*
Address of a pointer to an ID3DXBuffer interface. When the method returns, this parameter is filled with an array of three DWORDs per face that specify the three neighbors for each face in the mesh. NULL can be specified.
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_INVALIDCALL, D3DXERR_INVALIDDATA, E_OUTOFMEMORY.
Remarks
The created sphere is centered at the origin, and its axis is aligned with the z-axis.
This function creates a mesh with the D3DXMESH_MANAGED creation option and D3DFVF_XYZ | D3DFVF_NORMAL flexible vertex format (FVF).
