Raycaster from Planet Disco
« on: February 20, 2012, 12:35:35 pm »
So I decided to make my very own (extremely hard to see) disco-caster for my Flashlight Demo thread. It was actually really easy, from what I already in the the flashlight demo.



(in retrospect I went a little crazy on the psychedelic wall effects)

Waaaah O.O

That's a bad thing that nobody already made a tuto on raycasting (3D is the ultime goal of an on-calc programmer XD )

yeah, but that's compressed programs, with ununderstable code (what, I'm a newbie ?)

Compressed programs? Neither of the three have any sort of compression going on (that I know of), it's just regular Axe.

I assume you're refferring to the "fishbowl" type effect, with non-linearly sloped walls and whatnot?

Yeah. I know the theory behind how to deal with it but iirc whenever I tried to implement it it never worked...I should work on that again sometime

I believe to fix the fishbowl effect you just need to multiply the ray distance by the Cos() of the angle between your front view and the angle of the ray.  Obviously this would be a bit tricky in Axe since Cos() returns a number from -127 to 128 so you would need to make sure you handled that properly, or got a hold of a trig routine that returns x256 format, or better yet, make a 96 byte table for the 96 possible cos values.
