I wanted to make a little demo for a console with Realm of the Mad God esc graphics to brush up my C and SDL skills.
One problem I'm running in to is creating the 3D walls. The console I'm working with does not actually allow for 3D hardware acceleration at this moment of time and thus I can't really use real 3D. I noticed the perspective looked off in RotMG as well so I figured they must be using fake 3D also.
Now I have tried layering 2d textures on top of eachother as detailed here although this didn't quite work out so I modified the algorithm a bit and the blocks looked a lot better. Problem is they wouldn't sit next to eachother convincingly so I figured this is not the right tool for the job.
What type of algorithm should I use to recreate the 3D walls without actually using GL or other real 3D technologies?
