when i run the program, and i check for the normal of the surface i collide with, i get this in my debug:

Impacted Normal----
-1.#IND
-1.#IND
-1.#IND

it doesn't matter what direction the normal is facing.
i need normals here, not because i'm working with light, but
because i'm working with collisions. it'll help me figure out the sliding.

Am i not doing something wrong?
