USE TURBOWARP! https://turbowarp.org/1261565988 I made this project a while ago, but never shared it until now. There's still a lot of optimization that could be done, especialy with the skybox rendering but it is already quite fast as for scratch. I used a slightly modified version of this triangle filler by @3TheHedgehogCoder3: https://scratch.mit.edu/projects/1037654707 W/A/S/D/Q/E to move Arrows to rotate camera You can use this engine for your projects if you want, however let me know so I can explain how to import .obj files and other stuff
