DirectX7.QuaternionSlerp

The DirectX7.QuaternionSlerp method interpolated between two quaternion types, using spherical linear interpolation.

object.QuaternionSlerp(quat As D3DRMQUATERNION, _
    quatA As D3DRMQUATERNION, _
    quatB As D3DRMQUATERNION, _
    alpha As Single)

object: Object expression that resolves to a DirectX7 object.
quat: The D3DRMQUATERNION type that will contain the interpolation.
quatA and quatB: The D3DRMQUATERNION types that are used as the starting and ending points for the interpolation, respectively.
alpha: Value between 0 and 1 that specifies how far to interpolate between quatA and quatB.

If the method fails, an error is raised and Err.Number is set.
