#92 Uniform Mesh Resampling & assertion failed

[Michele Sottile]

Uniform Mesh Resampling on some meshes produces assertion failed.

Operative System: Windows Media Center Edition sp2

Last update:

• vcglib revision 3238
• meshlab revison 3069

To repeat the bug on screwdriver.ply:

1. Open Meshlab in debug;
2. Open screwdriver.ply;
3. Select Filters->Remeshing, Simplification and Reconstruction-> Uniform Mesh Resampling
4. Apply filter with default parameters-> Assertion failed

look at the attached file for assertion screenshot (screenshot1.jpg)

I have the same assertion on MacOSX trying a uniform resampling with default parameters of a mesh representing a brain.
