The midterm will be in class on March 17th.

You can bring 2 regular sided pages (front and back) of notes with you
to refer to during the exam.  These pages will be most useful to you
are very familiar with what is stored on them so that you only need
them to, for example, look up a formula you may have forgotten.  I
especially do *not* suggest having a friend prepare your pages for
you.

In general test questions will stress understanding over memorization.

Everything in the lecture notes posted on the class website is potential
material for the exam.  The same applies for anything that was discussed
during class.  

You should in particular study the following topics, both from the notes 
and from the text book:


    2D and 3D Transformations
        Translation
        Scale
        Rotation 
        Shear
        Rotation about an arbitrary axis
        Singular value and polar decompositions


    Homogeneous coordinates
        Representing points and directions
Normalizing
        Transformations as homogenized matrices


    Orthographic and Perspective Viewing

    Clipping
        Clipping lines/polygons in 2D
        Clipping lines/polygons against a plane in 3D
Testing to see what side of a plane a point is on


    Hidden Surface Algorithms
        Z and A Buffer algorithms
