Ok I want to get into raycasting and doing 3d models in turing (dont ask why, i just have tons of time on my hands) anyway I have no idea where to START! Like to do raycasting I read that tutorial that somebody posted, but how do i start where do i start??

anyways, raycasting isn't 3D, it's pseudo-3D. So I don't think you can do 3D modeling with raycasting.

and as I recall, you start where the tutorial tells you to start Razz

maybe start by making a map? Razz

like it said on the tutorial:
Quote:

Now that we have the world, we need to define some attributes before we can project and render the world. Specifically, we need to know these attributes:

1. Player/viewer's height, player's field of view (FOV), and player's position.
2. Projection plane's dimension.
3. Relationship between player and projection plane.

that was the first step I believe?

seriously though, just follow the tutorial step by step, you should have no problem...

if not, then follow SilverSprite's code, it explains alot.

blah... if you want to get started.. start offf with a 2 dimensional map with a grid (the map of your field) and a small player. give him the ability to move around the map but not through walls.. thats the first step.. it was for me..

Yes I would do it in C++ or something, but I dont have THAT much free time to spend on it, plus my school doesnt teach that and this is for a project for next year, Im just trying to get a head start, cause I wanna make something that is a REAL challenge
