from 2d engine,strictly. So using tools and readily implementations, to create full 3d illussions using just sprites?
There is an implementation of a simple ray tracer in the ANSI Common Lisp book.
just store their 3d bounds and include some way to check if a point is inside them
then step a point in a selected direction until it is within an object's bounds; it has now hit that object
you can use a bunch of these to hack-ily implement 3d rendering by sending a ray out for every pixel
First you have to learn capitalization rules. They're essential in programming.
