The first screeny:
I was having trouble finding a source explaining the perspective transform matrix for the last few days so I just decided to work it out using old fashioned pen and paper today in school. It was surprisingly easy and the matrix I got worked without needing adjustment. I'm ever so slightly chuffed [smile]
That is just a box composed of lines that I have rotating and moving around. Next job is to get it rendering the same box using wireframe tris, then I'll get onto filling them and sorting them.
