Live Lecture Chat – February 3, 2021
This started out as a normal Live Lecture plus Office Hours, but then the strangeness of Week #5 took over. Read on…
10:36:58 From Todankar, Diksha Pritam to Everyone : so we are using two sets of shaders for each pass [shadows] …then for each additional light source do we need an extra set of shaders?
Each pass uses one vertex/fragment combination. Multiple light sources could use the same GetDepth shader program, but with a different light position.
10:38:45 From Todankar, Diksha Pritam to Everyone : that just means we are doing the same operation for multiple light sources then?
Yes. So, the number of passes will be: (# light sources) + 1
10:50:31 From Todankar, Diksha Pritam to Everyone : what were the other 3 parts in the texture
vec4 (the one where we get the closest depth from)? just curious
I was going to guess “just garbage”, but then I thought I should actually go try it out. Turns out (at least on my graphics card and driver) that that single channel texture (.r) got identically copied to the .g and the .b channels as well, but not to the .a channel. That is, reading the depth texture’s .r, .g, or .b channel gave the same correct results. But, reading the .a channel didn’t work at all. Looking at the 2D grayscale display of the .a channel showed all white.
The conversation later turned to resumes and the fact that you should take credit for “transferrable skills” on your resume, and the fact that I once had a summer job working at a Taco Bell when I was in college…
11:04:29 From Arman H. to Everyone : Taco Bell?
Yes, afraid so. I was younger and more foolish then. They have more of an emphasis on “healthy” now.
The conversation later turned to cryptocurrency…
11:58:47 From Koning, Jonathan Scott to Everyone : John Oliver explains crypto
An alert student found this page full of great cube maps… 13:16:33 From Bailey, Mike to Everyone :

Then, in the middle of Office Hours, I got an email from the Disney Store talking about their Disney-themed Valentine’s Day specials…
13:19:37 From Bailey, Mike to Everyone : Disney Valentines:

Nothing says “I Love You” quite like a $15 Baby Yoda card, I always say…
