How do 3d games work?
« on: August 29, 2011, 02:03:23 pm »
I was wondering about how 3d games work, so I can make one myself. I'd like to know how to make a 3d engine that can do 360 x,y, and z. I'd also like it to be done in luaFX when finished, but I only want to know the basics right now (the theory, formulas, etc.).

What type of 3d graphics are you talking about? 3D wireframes? Wolfenstein? The jets in your signature? Also, do arbitrary viewpoints have to be supported? What about rotating frames? How high quality does the rendering need to be?

Basically, there's a huge field of stuff out there. It'd help others tremendously if you were a bit more specific about your eventual goals :P

1) this is in "humor and jokes", which is the wrong place for anything besides funny jokes, obviously :P

2) they work in multiple ways.  Too many ways to sum up in a paragraph, a post, possibly even a thread.  What do you want to work with?  What language?  Low level or high level graphics interfacing?  What *specific* questions?  Did you look at any tutorials first, or do you need help finding some good ones?

I know that wikipedia is unreliable, but it is a good place to get started.  It barely even scrapes the top, but you can get more of a feel of 3d games.

Wikipedia is unreliable *for certain topics*. As far as technical materials go, it's generally an excellent resource.

I got a whole course at school on 3D, there's a lot of stuff. Also involves matrices.

Wait, do you want a wireframe first person game? Because fixed 3d means the camera does not move at all.
