D3DXCreatePolygon

Uses a left-handed coordinate system to create a mesh containing an n-sided polygon.

HRESULT D3DXCreatePolygon(
  LPDIRECT3DDEVICE9 pDevice,
  FLOAT Length,
  UINT Sides,
  LPD3DXMESH * ppMesh,
  LPD3DXBUFFER * ppAdjacency
);

Parameters

pDevice

[in] Pointer to an IDirect3DDevice9 interface, representing the device associated with the created polygon mesh.

Length

[in] Length of each side.

Sides

[in] Number of sides for the polygon. Value must be greater than or equal to 3.

ppMesh

[out] Address of a pointer to the output shape, an ID3DXMesh interface.

ppAdjacency

[out] 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 Values

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 polygon is centered at the origin.

This function creates a mesh with the D3DXMESH_MANAGED creation option and D3DFVF_XYZ | D3DFVF_NORMAL flexible vertex format (FVF).
