Just finished up some math homework

One of the problems involved finding the side lengths of a triangle

Spend a good 20 minutes fucking around with the law of sines and the law of cosines before I realized it was a right triangle, and so I could use the Pythagorean theorem

I'm an idiot

FUCK ME IN MY INDICES.
FUCK THE GPUS IN THEIR INDICES.

I mean... I understand (roughly) why the meshes are sent to gpu in this form, but at the same time...
...there's a reason why first thing I did when I was coding my procedural geometry generation library, was abstracting away all of that stuff...

...sadly, as many useful things, when I was looking for that lib on the start of this contract, I couldn't find it. and I was like "doesn't matter, this is a simple thing, using the library would be just a lazy overkill anyway".

well, fuck.
two hours of playing around with two fucking triangles, trying to figure out which indexes are pointing to the correct vertices in a list containing FOUR outline paths.
(lower inner, upper inner, lower outer, upper outer, exacly in this order).

i mean, yeah, it's actually pretty straightforward stuff... for someone not as dumb as me =D
you just have two offsets, one that jumps you to start of the upper path, another that jumps you to the start of the outer path, then it's just
0 + upOffset to get the vertex extruded upwards from the zeroth of the inner path, or
0 + outOffset to get the zeroth from the outer outline, or
0 + outOffset + upOffset, to get the one extruded from zeroth outer vertex...

and so on.
simple stuff, then you just replace the zero with loop control var, put them in the right order, and voilá! walls!
except... whatever, why am I describing in such detail, not necessary, you're not my rubber duck =D

in short, figuring out which fuckin vertex is which, when the list contains ...well, any number of points, and you need to plug the gap between last and first points of the paths, where you need to wrap around the list...

...has proven to be surprisingly hard for me.

funny how much I love doing these things with meshes, despite how bad I am at doing them, which makes me hate doing them despite loving it =D

NO FUCKING WONDER I SUCKED-ASS IN HIGH SCHOOL ALGEBRA!!!!!

Arghgghhghgh ughhh....

I want to beef up the hell out of my Maths Chops so I can maybe try going back to school for a A.S. in EE or hell even an B.S.

I'm using my company's Safari Learning account for getting free-ish access to college algebra books and I'm self studying.

I'm still in Chapter 0 where the book covers shit you're supposed to know from previous years of education. I'm just learning about some of this shit now!!!

While it's possible that I didn't pay attention in high school lectures, I took geometry in 9th grade and was an A/B+ student and felt confident in maths. I got to Algebra II in High School and suddenly nothing made sense anymore, reality fucking-fell-apart!

Suddenly, I'm failing tests left and right and struggling with the lecture concepts and I could never seem to grasp materials covered in class anymore to even be able to finish the homework assignments.

Fast forward to me being 15 years older and wanting to take a stab at this shit again, but with new found determination to get into EE so I can fuck around with small electronics for pet projects I want to do. I'm starting with College Algebra to try and learn when suddenly, low and behold I have a HUGE FUCK-MOTHERING GAP in my core understanding of the language/syntax/grammar of mathematics.

Been fucking knee-capped for the last decade+ because I either slacked off during those fundamental lectures (which again; is totally plausible) or I had a complete fucking imbecile for a math teacher that glossed over the topics and fucked not only me but the 40+ other kids in that class.

I'm not going to blame the teacher, although I really fucking want to, but I can't remember how the class scored on tests or homework to be able to fairly and objectively make that judgement against the educator.

FUCK!!! I hate my 15 y.o. self right now

I fucking hate math. Today tried to make 2 unequal rectangles align along 1 axis. This isn't that hard when they aren't rotated but it fucking when they are rotated. I know I have to use geometry to get them aligned and I got it somewat working but as the gap is bigger so is the drift in which it over compensates to the other side and I have no fucking clue how to fix this 😩.

The worst thing is tomorrow I have to be at this again
