Both. A bit of simple, OpenGL related coding (like how you might

render an object with colors, normals, and texture coordinates). A few

small computations (ray intersection [see below], framebuffer memory,

aspect ratio, etc.). Also a working knowledge of definitions:

coordinate spaces (eye, model, world, etc.), blending functions,

geometry matrices, matrix transformations, etc. I won't ask you write

down a definition, but you will need to know what said objects are so

that you know how to use them.

For ray tracing, either a simple sphere or plane (with possible a

geometric primitive in it). For bounding spheres and culling, knowing

the magic relationship between the parameters that describe a bounding

sphere (center, radius), and how you might apply that (computing the

distance from a point to a plane), would be useful bits of information

to know.

You're welcome. I must say, however, that this email by no means

guarantees any aforementioned topic will be or will not be included in

the exam, and is not binding in any way upon me. :)

--Thanx, Dave
