I'm trying to make a vector-based game in java, but I can't figure out how to get the intersection point of a ray with a surface. This is a fairly important thing to be missing, so any help would be appreciated.

I still can't believe I forgot to search google. There's also some dumb problem with how my vectors are getting multiplied together. Probably my dumb problem. Argh.

Thanks for the help though.
