[@pelle1722]

this professor is a true blessing

[@owen7666]

his handwriting is beautiful

[@carvoloco4229]

Except for when he can't be bothered to complete an explanation

[@rezNezami]

A very important point in BSP method (before Min 19) is that the positive direction of each polygon should be the one that contains the viewer.

[@bs140598]

wow so basically we will ignore the left child and its successors of root polygon because viewer will never see it :D.

[@DaffyDuckTheWizzard]

Wow, he actually mentioned Bob Ross as a reference for the algo!

[@Flypotato9]

instead of studying for my finals I'm watching this... wtf am I doing !

[@biboswanroy6699]

I long for such lectures in my classroom

[@tzisorey]

A lecture from that weird period in time, when we taught people how to program a computer, but had to do it on a blackboard.

Tzisorey Tigerwuf This is from 2009 lol, he could’ve just used a projector and PowerPoint if he wanted to.

[@DaffyDuckTheWizzard]

Most institutions substituted it for whiteboards and PowerPoints, though

[@tzisorey]

I remember doing programming in school in the early 90's. You'd have to submit your code on floppy disk, but for some reason, also a hand-drawn pseudo-code or flowchart, and a (dot-matrix) print out of the actual code. It was all Pascal and COBOL, too. I don't even know if Pascal still exists... and I'm pretty sure that COBOL doesn't.

[@khoavo5758]

It’s still the best (or one of the best) things we’ve got. Pre-made slides and computer graphics don’t really replace chalkboards.

"Warnock" is spelled wrong in the description.
