double operator * (  const Vector &    a,
const Vector &    b
)  [friend]
 

operator * calculates the dot-product between two vectors

Parameters:
a  the first vector

Multiply vector with a matrix from the right. The matrix is assumed to be a 4x4 matrix as a double[16] in column-major order (like for OpenGL). Only the upper left 3x3 part of the matrix is used.

Parameters:
a  the vector v
d  the matrix A
Returns:
the vector (v*A)*
