I made this demo as a few students of the Interactive Graphics MOOC were asking for something showing the various transforms from beginning to end.<\/p>\n

It’s not a fantastic demo (yet), but if you roughly understand the pipeline, you can then look at a given point and see how it goes through each transform.<\/p>\n

It’s actually kind of a fun puzzle or guessing game, if you understand the transforms: if I pan, what values will change? What if I change the field of view, or the near plane?<\/p>\n

I’d love suggestions. I can imagine ways to help guide the user with what various coordinate transforms mean, e.g. putting up a pixel grid and labeling it when just the window coordinates transform is selected, or maybe a second window showing a side view and the frustum (but I’m not sure what I’d put in that window, or what view to use for an arbitrary camera).<\/p>\n

I’ve been bumping into limitations of three.js as it is, but I’m on a roll so that’s why I’m asking.<\/p>\n
