| Jul 31 at 20:41 | comment | added | Greg Hurst | @DanielCastro per youtu.be/eza70O2avZ4?si=tK8LZgFZUAMoRihy. Is their code available yet? I wasn’t ever able to find a project page with linked code. | |
| Jul 28 at 10:04 | comment | added | azerbajdzan | @DanielCastro It is either a bug in ListPlot3D or a consequence of an interpolation algorithm they use in ListPlot3D which is not perfect. I can not do anything about it. | |
| Jul 28 at 9:50 | comment | added | Daniel Castro | This is cool, thanks. There are some minor defects on the sides, I suppose this is due to the interpolation, right ? | |

| Jul 27 at 20:05 | comment | added | Daniel Castro | True, they are using different parametrizations. I am using a "Chebyshev parametrization" which explicitly enforces the aforementioned property. Of course I did not do that implementation, the credit goes to these guys: youtu.be/eza70O2avZ4?si=tK8LZgFZUAMoRihy | |
| Jul 27 at 20:02 | comment | added | azerbajdzan | @DanielCastro Why do you assume lengths of black squares should be the same? If you look at the igl link in your OP, in the first image of a camel head we see huge black square in the tip of the nose of the camel while squares on its neck are very small. | |
| Jul 27 at 19:57 | comment | added | Daniel Castro | Thanks, this is useful. However it's not the same for two reasons. (1) If we look carefully your checkerboard pattern is not perfect, in the sense that the distances of all the edges are supposed to be the same. Such a Chebyshev net, as is called, is generated with the parametrization data. (2) I'm not sure how easily we can extract here the quad mesh spanned by the checkerboard pattern. | |
