D3DX11SHProjectCubeMap function

Note  The D3DX (D3DX 9, D3DX 10, and D3DX 11) utility library is deprecated for Windows 8 and is not supported for Windows Store apps.

Note  Instead of using this function, we recommend that you use the Spherical Harmonics Math library, SHProjectCubeMap.

Projects a function represented in a cube map into spherical harmonics.

Syntax

HRESULT D3DX11SHProjectCubeMap(
  ID3D11DeviceContext *pContext,
  UINT Order,
  ID3D11Texture2D *pCubeMap,
  FLOAT *pROut,
  FLOAT *pGOut,
  FLOAT *pBOut
);

Parameters

pContext

Type: ID3D11DeviceContext*

A pointer to an ID3D11DeviceContext object.

Order

Type: UINT

Order of the SH evaluation, generates Order^2 coefficients whose degree is Order-1. Valid range is between 2 and 6.

pCubeMap

Type: ID3D11Texture2D*

A pointer to an ID3D11Texture2D that represents a cubemap that is going to be projected into spherical harmonics.

pROut

Type: FLOAT*

Output SH vector for red.

pGOut

Type: FLOAT*

Output SH vector for green.

pBOut

Type: FLOAT*

Output SH vector for blue.

Return value

Type: HRESULT

The return value is one of the values listed in Direct3D 11 Return Codes.
