Calculates the exponential.

pOut Microsoft.DirectX.Quaternion. The Quaternion structure that is the exponential of the pQuat parameter. pQuat Microsoft.DirectX.Quaternion. Source Quaternion structure.
Microsoft.DirectX.Quaternion . The Quaternion structure that is the exponential of the pQuat parameter.
The Exp method converts a pure quaternion to a unit quaternion. The method expects a pure quaternion, where w is ignored in the calculation (w == 0). In the following example, v represents the vector portion of a quaternion.
Given a pure quaternion defined by: q = (0, theta * v); This method calculates the exponential result. exp(Q) = (cos(theta), sin(theta) * v)The return value for this method is the same value returned in the pOut parameter. Resultantly, the Exp method can be used as a parameter for another method.
