I don't think I have time to go through the steps but I'm gonna link you my favorite eBook that has it in pure C++ (mixed with a little DirectX but was only need for memory addressing to access the video card to draw pixels blazing fast so its not needed) over in Chapter 13 where it says Binary Space Partion. It can easily be ported to VB.Net and is very accurate. The book teaches you how to create a full blown 3D engine which I once ported to pure VB6 using their direct memory addressing concept. Drawing pixels using that was 1000 times faster than using the SetPixelV API and even more faster than PSet. Was able to flood an entire screen of 640x480 at 60 FPS. The book is 49 megs but I also own the real book and its huge. It even covers perspective correct texture mapping which I also once done in VB6. You can download the book here:
