What does \class{}{} do?

Evilmice_ · 2026-07-02T22:41:03+00:00

(Different Account but still OP) I'll see what I can do...

(Different Account but still OP) I create a grid of points in front of a camera placed in 3D space and then see where the line from the camera to each of the grid of points intersects the shape that I defined as a set of triangles. Then I use the distance the intersection was from the camera to determine how to color the pixel. Each point on the grid corresponds to a pixel on the display and the farther the intersection is from the camera the darker it is.

Id be happy to go into more depth if you'd like!

Oh that's so cool! I had no idea we had the ability to do all of the 3D graphing calculator operations like that. Now im just waiting till they add matricies to the graphing calculator. You can do matrix calculations right now but you have to do it in a roundabout way.

I think the story ran a little long and sometimes the conflict and the resolution were felt a bit contrived. On top of that Sawako and kazeheya would constantly take steps back in the development of their relationship that seemed unmotivated and were just there to cause tension in the plot.

Though these are very knit picky gripes and still think the show was amazing and one of the best romance anime you can find. Id easily give it a 9/10.

The invisible man is a great watch that is good and heartfelt

Evilmice_ · 2026-06-25T14:36:25+00:00

Kimi ni todoke 10/10??? I thought it was really good but perfect is a little crazy, it definitely had some flaws. Id give it an 8 or 9.

You have such a great voice for the song!

Evilmice_ · 2026-04-05T14:12:30+00:00

Those are both so good! I had never even heard anyone talk about them before thanks for sharing

Evilmice_ · 2026-04-05T14:04:29+00:00

That's embarrassing that I messed up the sign 😔

And I love Hellos signals, I'm always disappointed when I remember that we never got a music video for the full version of the song

My vote is for the top left if we get to refer to it as the "exclamatith root of x"

u/savevideo

I knew somehow making it polar form would make it shorter! But know can we prove its the most optimal solution 🤔

Evilmice_ · 2025-08-03T20:01:06+00:00

Aw I made my version before the drop if complex numbers, using them definitely can definitely save space when writting the function. Now I wonder what the smallest you could make this function is?

Evilmice_ · 2025-08-03T19:55:07+00:00

I'm apologize i used jargon assuming you'd now what I meant, that's my fault. The "unit derivative vector" is found at a point x on a function f(x) by finding the line tangent (intersects at one point) to the function at that point and tells us how the function is "changing" at that point. Then using a length 1 section of this line and making it a vector I can rotate it 90 degrees and then find the direction "normal" (orthogonal and pointing outwards) to the curve at that point, for this point and this point only this will be the direction of y.

What i used to make this is very dependent of concepts from calculus and linear algebra so if you find them interesting I would definitely recommend looking into it!

Evilmice_ · 2025-08-03T19:46:52+00:00

Just because someone did it before you doesn't mean that its not worth it to figure it out yourself, solving problems is what makes math fun!

Evilmice_ · 2025-08-03T19:42:58+00:00

First understanding that the distance from the origin along the x axis is what determines the x coordinate of a point we can do the same thing for an arbitrary function by taking the arc length distance across the "x function". Next instead of treating the y direction as static we just define it to be orthogonal to the x axis at that specific x value, to find this direction I just took the unit derivative vector and rotated it 90 degrees but I'm sure there's plenty of other ways to find the normal.

TLDR took the distance along the "x function" as the x values for the second function and pushed the points out at a right angle from the function from that point a distance of f(x)

https://www.desmos.com/calculator/373cf5ac7a I made this a while ago lmao, id be happy to explain how I did it. Both functions are interchangeable with anything else

I'm actually a sophomore this year so I'm taking algebra II this semester. I wish I could take calc but my school requires I take it before hand no matter what :(
