>using some basic trigonometry
You just described ALL 3D computer graphics, no exceptions. Voxels, polygons, point clouds, it doesn't matter, the very foundation of 3D graphics is a projection onto a virtual screen, which is basic trigonometry. The rest is just data structures, optimizations (ways to save computations) and approximations (adding simplified assumptions and restrictions in order to save math. Raycasters and Mode 7 are examples of this)
