D3DXMatrixShadow

The D3DXMatrixShadow function builds a matrix which flattens geometry into a plane.

D3DXMATRIX* D3DXMatrixShadow(
  D3DXMATRIX* pOut,
  const D3DXVECTOR4* pLight,
  const D3DXPLANE* pPlane
); 

Parameters

pOut

A pointer to the D3DXMATRIX structure that is the result of the operation.

pLight

A pointer to a D3DXVECTOR4 structure describing the light's position.

pPlane

The pointer to the source D3DXPLANE structure.

Return Values

A pointer to a D3DXMATRIX structure which flattens geometry into a plane.

Remarks

The D3DXMatrixShadow function flattens geometry into a plane, as if casting a shadow from a light.

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXMatrixShadow function can be used as a parameter for another function.
