2.5D engine

For those who don't know, 2.5D is basically 2D, but with distance falloff(basically a 3D engine without rotation). For example, Fallout Shelter. Since there is no trigonometry being done, this should(theoretically) be a good 3D engine alternative

I am currently working on this processing - cheap method of perspective. The good thing with a 2.5D engine is that texturing can be done to any extent(ie textures that are 512x512). I know P3D exists and can do 3D texturing, but this should be upwards of 10x faster, due to:

• Less math
• this can be utilized (if modified) to rotate at 90º angles(since sin/cos would be -1,0 or 1; integers; FAST)

Since this is dull, I will plan to add a modeling software and per - tri/quad FOV occlusion, among other optimizations, such as clipping, (hopefully LODS, which will be pre-generated), distance culling
