D3DXQuaternionSlerp

The D3DXQuaternionSlerp function interpolates between two quaternions, using spherical linear interpolation.

D3DXQUATERNION* D3DXQuaternionSlerp(
  D3DXQUATERNION* pOut,
  const D3DXQUATERNION* pQ1,
  const D3DXQUATERNION* pQ2,
  float t
); 

Parameters

pOut

A pointer to the D3DXQUATERNION structure that is the result of the operation.

pQ1

A pointer to a source D3DXQUATERNION structure.

pQ2

A pointer to a source D3DXQUATERNION structure.

t

This value specifies how far to interpolate between the two given quaternions.

Return Values

A pointer to a D3DXQUATERNION structure that is the result of the interpolation.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXQuaternionSlerp function can be used as a parameter for another function.
