Colorize Curvature Apss filter crashes #50

Open Ainaz99 opened 3 years ago

Ainaz99 commented 3 years ago

Hi,

I'm trying to apply the colorize_curvature_apss filter with curvaturetype=K1, K2 on a sample mesh, but it crashes. This is the error I get:

*** Error in `python': double free or corruption (out): 0x000055f146d82bf0 ***

Here's the link to the mesh: https://drive.google.com/file/d/1x0Ui0_zpOO8abvuzt3_jb3VA-sCNUjP7/view?usp=sharing I would really appreciate it if you can help me fix this problem. Thanks in advance.

Thanks for reporting this. The issue occurs also in MeshLab, and it is because the k1/k2 curvature has a NaN value on some vertices. I'll investigate on why this is happening and how to prevent it.
