Thank you, glad you like it. And thanks for the report. Are you able to reproduce it again? I could not reproduce it. If so, could you provide more details or even better, open an issue at https://github.com/ndavd/ncube/issues https://github.com/ndavd/ncube/issues

It totally crashed my FF on macOS Sonoma Edit: Here's the bug as a screen cap: https://vimeo.com/893937641/e7d12262c8 https://vimeo.com/893937641/e7d12262c8

  From the provided recording it seems to be working properly. Keep in mind that in most hardware I wouldn't even try to go beyond the 7th/8th dimension. It becomes too intensive, way too many vertices, edges and faces to calculate. There's an on-going issue to attempt to move some logic into compute shaders.

    is it that the axis of rotation changes? the animation looks totally different after the reset. unfortunately, it has crashed my browser 3 separate occasions now, so that's putting a limit on further playing with it.

      I gave an answer to that animation behavior in a comment bellow https://news.ycombinator.com/item?id=38621273 https://news.ycombinator.com/item?id=38621273 Also, please test out the native version of ncube, I provide some pre-compiled binaries for Mac, Linux and Windows. They should perform better. The web port was a nice to have, but the native versions will always perform way better.

When moving from 5->4 the w sliders are [0,0,0.5,1,0,0]. When moving from 4->3 they become [0,0,1]. When moving from 3->4 they become [0,0,0,1,0,0]. Clicking 'reset' or manually changing the w slider to [0,0,0.5,1,0,0] results in the expected animation.

  Might seem counter intuitive but that's the intended behavior. Instead of looking at the order of values think of it as the angular velocity state associated with a rotation plane. Worth noting that q1q4, for example, refers to the rotation plane of the 1st and 4th dimensions. 5: q1q4 = 0.5, q2q3 = 1.0, rest = 0.0 5->4: q1q4 = 0.5, q2q3 = 1.0, rest = 0.0 4->3: We no longer have the q1q4 plane available therefore q2q3 = 1.0, rest = 0.0 3->4: Now we have the q1q4 plane back but the state has been cleared from previous interactions Going to a lower dimension essentially deletes previously set state of higher dimensional planes because they don't exist at that point. When resetting it just goes back to the default configuration.

    This makes sense. Please excuse my post!

      No problem! I'm glad it cleared your doubts.
