Thanks. I have 3 days of vacation ahead so will use the time to sort out the math first. Code shouldn’t be too hard for a very simple 3d demo.

I tried my hand on hand a while ago and found out I couldn’t make out how many pixels to draw, say, a line in the 3d world. It involves a transformation to the world and another transformation to the camera, so I couldn’t make it out without any study.

This is probably very trivial so hopefully 3 days is good enough.
