- Is there a way to hide the menu on mobile? The few pixels I can see do look pretty cool.by ks2048
- This is awesome, what an incredible project!by gotfork
- Great app to play around with. I thought I can think of the implicit form for a cube. I couldn’t (how embarrassing). It’s:
f(x,y,z) = max(|x|, |y|, |z|) - const.
by mif - Very nice. I've been inspired by the same sources and have always wanted a way to render such drawings for any arbitrary 3D model (e.g. STL file). I've played around with that quite a bit, even recently with LLM assistance, but haven't yet gotten it as good as I want. Eventually...!by fogleman
- The spacing and style of the hand sketched lines are really perfect. Was it hard get such clean drawings, even using principal curvature fields?by ekzhang
- In addition to making the sidebar dismissable on small screens, it'd be nice to add touch-action: none to the canvas so rotating the object doesn't get interpreted as a scroll on touchscreens.
Right now, at least in Android Chrome, dragging to rotate only works briefly before it's interrupted.
by sheept - I was an undergraduate student of George's many years ago and it's an absolute delight to see these renderings. He used to doodle them on any available surface -- blackboards, notebook paper, napkins, what have you -- often with a fountain pen. He was also big into using computers for visualization and had a number of programs that ran in the CAVE.by sevensor
- This is my project — thanks for the interest. I just made it more mobile / small device friendly.
The app is primarily based on ideas of Hertzmann and Zorin in [this paper](https://cims.nyu.edu/gcl/papers/hertzmann2000iss.pdf), using directions of principal curvature for hatching directions.
