To Do To Do Start (thinking about) assignment 1 Much of information you need is in this lecture (slides) Ask TA NOW if compilation problems, visual C++ etc. Not that much coding [solution is approx. 20 lines, but you may need more to implement basic matrix/vector math], but some thinking and debugging likely involved Specifics of HW 1 Axis-angle rotation and gluLookAt most useful (essential?). These are not covered in text (look at slides). You probably only need final results, but try understanding derivations. Problems in text help understanding material. Usually, we have review sessions per unit, but this one before midterm

Motivation Motivation Many different coordinate systems in graphics World, model, body, arms, … To relate them, we must transform between them Also, for modeling objects. I have a teapot, but Want to place it at correct location in the world Want to view it from different angles (HW 1) Want to scale it to make it bigger or smaller
