holy shit, I’m so flattered! Thank you for your kind support and encouragement!

It’s crazy that it looks okaish right? quaternions, dude. I have implemented them in 3 projects and still have no fucking idea how they work.

Also, you can run it in --quality low if you’re struggling with framerate. :)

lazy

Thank you for your inspiration <3

I fucked that sentence up, but you understand what I mean! ∆<3

I forgot to tell you how much I appreciate this meme. heh. thanks!

I changed my mind.

Well, you guys are making some p good points. I’ll probably end up sharing it, but’ll give it a clean up, try to fix some bugs and improve my comments before posting it publicly. For now whoever really wants it (including you) can just ask and I’ll dm it, understanding it will be a hard read and still has bugs.

i’m just gonna pastebin it for now but yeah, thanks for the encouragement.

you make good points

here ya go

I’ll do a follow up post when I upload

what video hosting service works for you?

Yes, the values are rendered on top of each face with “pixel” maps (ascii art) that have the character of the digit they represent as each pixel. These are later manipulated by the perspective projection.

For example on this d6 you can see the top face has 1s written down (in the shape of a sideways one) and the front one has 4s written down in the shape of a skewed and sideways 4.

In this specific color scheme there’s not a lot of contrast between the values, but even in the palettes with better contrast, good readability is something I’m kind of giving up on solving well.

edit: might be clearer here:

I didn’t have the patience to do it myself bit wanted to see just how complex it would get:

Invert the gravity value and then all the dice will be floating point 🫣

hahaha you seem to be familiar with the issues I ran across

yeah, I was trying to stay as pure-bash as possible, but thanks!
