Re: [racket-users] sharing an awesome plot - warms the cockles of my heart
Thanks so much Mr. Williams. I posted that last item then disappeared - I had one of my CPA exams (I failed, but i always think that after an exam) & just had to force myself not to check my email for a couple of days. I hope it didn't take you too long. Unless, like me, you program like some people play video games. If so, I hope it kept you up all night ; ) On Tue, Mar 27, 2018 at 11:23 AM, Doug Williams < m.douglas.willi...@gmail.com> wrote: > Sanjeev and I took this discussion offline to iterate over some details. > But, I thought I would post some final thoughts on this.

Re: [racket-users] sharing an awesome plot - warms the cockles of my heart
what I'm seeing: the curve is quantized into squarish shapes ( the full resolution static plot has no angles, it's all curves) - and all the squares are rotating together - It occurred to me later it could be a symptom of monitor refresh rates so others may not see it.

I hit send a bit too fast. Here is the code (from the animate-canvas package on PLaneT) for the 3D animation.
