3D is definitely possible in Axe. In fact, I've done it before:



You can find the thread I made for this project, which I called YAAR, here. If you want to get an idea for how I did it, I attached a zip file containing the source and executable for it. Feel free to look at my code to learn how it works and maybe write your own engine, or you can just use my engine. If you do the latter, I would request that you please credit me for the raycasting engine in any project you make with it, though.

Sure, I'm not really doing anything with the engine so you can use it if you like. My only request is that if you use this engine, you credit me for my hard work making it.

Yes I will give credit WOAH +21 RESPECT FOR ONE POST!

Keep in mind that this is raycasting, which has more limitations in order to have a reasonable speed on the calculator.

I wondered from this, if it was possible to have true 3D, the kind where you could look up and down. And I found these.

It actually doesn't seem that complicated to be able to look up and down, I mean, here's the code to make a point look 3D

// initialize point

POINT3D point = { 5, -3, 2 };

// find the right position on the screen in 2D coordinates
int x2d = HALFWIDTH + point.x * ViewingDistance / point.z;
int y2d = HALFHEIGHT + point.y * ViewingDistance / point.z;

// project the 3D point to the screen
Pixel(x2d, y2d);
And here's the equations to move the camera

x'=z*sin(yaw)+x*cos(yaw)
y'=y
z'=z*cos(yaw)-x*sin(yaw)
x"=x'
y"=y'*cos(pitch)-z'*sin(pitch)
z"=y'*sin(pitch)+z'*cos(pitch)

x"'=y"*sin(roll)+x"*cos(roll)
y"'=y"*cos(roll)-x"*sin(roll)
z"'=z"
Idk how you could do it with planes and textures but, at least with points, it doesn't seem too taxing.

I could be completely and utterly wrong though. :S
