> Pomax is approaching the vanishing points exponentially rather than hyperbolically Exactly this. To put it in drawing terminology, the distance of a line towards the vanishing point is related to the angle from the camera (station point) projected back to the picture plane. Images like this may be of assistance for those of a computer and not hand drawing background https://guidetodrawing.com/site/assets/files/1082/gtd-235.798x0-is.jpg https://guidetodrawing.com/site/assets/files/1082/gtd-235.79... An exponential ratio as used by the article could maybe be described as assuming the camera is 0 distance from every point drawn. [Edit: Really great article though - the kind of thing I love to see is looking at a complex problem with established solutions from first principles again]

> An exponential ratio as used by the article could maybe be described as assuming the camera is 0 distance from every point drawn. Hmm, wouldn't that give you an orthographic or isometric projection, or another member of that family, rather than this crazy exponential thing?

That diagram is very confusing if you aren't aware that (1) the object being projected is a shed; (2) the perspective projection is incomplete.

I'm taking an online drawing perspective class right now, and finding that much of what I've been learning is covered right on that site! Pretty neat stuff.
