Dot Product Follow

Posted March 12  2016



"Dot Product
is the product of the magnitudes of the two vectors and the cosine of the angle between them. The name "dot product" is derived from the centered dot\cdot " that is often used to designate this operation."  See wiki entry. See the hip file for a demonstration.



Here is an excellent example using the dot product, pythagorean theorem and a little bit of vector math tossed in to solve an animation problem. Please see the hip file to correspond to this.
There are two similar problems in this section, two point constraint and train wheels.
