All this really depends on what language you want to do this on. (A viable example on Java)[https://youtu.be/KA6rJZOfTTQ]. I think what you want is basic software rendering, so be advised: software rendering gets really slow really fast.

I tried something akin to this a couple years back l, it didn't end too well, but I learned a ton in the process, feel free to (take a look )[https://github.com/jonnelafin/PB3D], but the code is crap, so I think you are better off on writing your own.

Also these are some wikipedia articles on perspective transformations etc:
