ND <-------------------
This is my N dimensional Cube / Square thing I have been working on.
I have already done a cube and sphere environment with raytracing but I was wondering If anyone has done some N Dimensional raycastings as that would be a cool project but my head is on fire due to the maths involved
Any Ideas?
Change Dimensions counter at top of code for different dimensions.
How do people make these!?
It builds the points from n d vectors using a n d cube function and creates an n d rotation matrix.
I could explain all of it.
Tell me If you get any ideas.
Neat! I modified it a bit to add a perspective transform, here’s the 4D version of that:
I used to have something like that but thought it was better at exactly 100 lines :).
Also try adding a trail to a random point and watching where it goes… Pretty interesting :).
My head hurts from watching it. 
Same here @UnsignedArduino. I think I lost some brain cells just from watching that 4D rotation thing for an hour. It’s really cool though… zzzzzzzz
A suggestion - it seems that the rotation is repeating and not showing all the mind-bending possible variations. Can you try using separate rotation speeds for the various axes so that they rotate more independently?
Yes you can just change the rotation rate at the bottom, the reason it repeats is because all rotation amounts are equal.
You can even hook the up to buttons to get a feel for it
Also Have you noticed how the circle function seems to make a kind of helmet shape ?
This was my original
all buttons including menu
Thought You might find this interesting:
terseract, right?
Yes, a Tesseract is the four-dimensional version of a cube: https://en.wikipedia.org/wiki/Tesseract
