- L38 It returns a single float value between
0.0and1.0depending on the alignment of two vectors.
in fact it is the Cosine of the angle formed by 2 vectors multiplied by the length of each vectors : cos( a ) * length( v0 ) * length( v1 ) if we use normalised vectors, the cos() is multiplied by 1 * 1 and returns a number between -1 and 1.
also, if the result is positive, both vectors point in the same direction, if zero, they're perpendicualer, if negative, they point in opposite directions.
