Sure, here they are: https://drive.google.com/drive/folders/1Rxw_sqVwG7cYULh9_h02tgySCU7Vxx2a?usp=sharing 0.ply is an empty mesh and 1.ply is a cube. You could also try to load both of them multiple times.

Hi, is it possible for this interface to generates the Delaunay tetrahedralization from points only, instead of a surface? With C++ tetgen this functionality is there (Figure 12 of http://wias-berlin.de/software/tetgen/1.5/doc/manual/manual005.html)....

Hi @MohameHassan , did you find any workaround on this?

Hi @raphaelsulzer, you're right that currently polygon soups are exported. I didn't manage to locate common vertices across cells in the first implementation. That was difficult with native Sage functions...

Also as a quick note: I'm not sure to what extent these functions in [Mapple](https://github.com/LiangliangNan/Easy3D/releases/tag/v2.5.2) could help you as a post-processing, in case an immediate fix is needed. CC @liangliangnan.

Thanks for sharing your solution here! For re-orientation, I have written some lines before (with rough edges) which may be integrated as a fix: https://gist.github.com/chenzhaiyu/179fde5aedd1f909bb6ab8145f4366d0 As mentioned before it would...

Sage itself should handle well its rational number types in the box - I have never bumped into any arithmetically degenerate cases using pure Sage. However, for operations outside Sage,...
