In this class, we will introduce the computations involved in graphics transformations by discussing a tensor called the vector cross. The required vector analysis background is reviewed as a repetition to assist those who may have forgotten and refresh your minds. The summation convention is used and a symbolic algebra tool like Mathematica will make life a lot easy for you. Please download these two notes in the event that we have no power on Thursday.
The above discussion will be needed to go through the worked examples presented here:
