Tutorial 13, Orthogonalization about ogl HOT 2 OPEN

Hi Baslack, thanks for your feedback.

The formulas you're suggestion are indeed the full Gram-Schmidt formulas, and should be correct. However, I don't think the current implementation is broken (although I admit there's a tricky shortcut) :

• By construction, t is orthogonal to n (line 37)
• By construction, b is orthogonal to n (line 38)
• The only missing part is that t should be orthogonal to b, too.
• Line 61 does just that.

Do you have a case where this breaks ?
Sincerely,

Nope, I don't. I just couldn't figure out what you were doing, which kinda of defeats the purpose of a tutorial.

And I still don't quite follow how line 61 makes t orthogonal to b. Looking at one of the references you mentioned: Lengyel’s Method. That line seems to match the first part of the projection process, but the second is missing, hence my addition. Could you explain in a bit more detail for me?
