#455 Pick Point Crashes

[Allan Keefe]

Hello,

Fantastic software, however, selecting PickPoints causes Meshlab 64bit v1.3.4BETA to crash. I've experienced this on all sample models as well as .obj files of my making.

Running Windows 10 with Intel HD Graphics 4000 on Lenovo T530 laptop.4Gb RAM. Recently upgraded from v1.3.3 due to select faces issue. PickPoints ran but gave problems (v slow) on that version as well.

Thank you,

Confirmed on Linux 1.3.3 version (for both 32 & 64bit). It crashes as soon as you left click anywhere under PickPoint mode.
Command line history:

...
LOG: 0 Started Mode PickPoints
meshlab: ../../../../src/mesa/vbo/vbo_exec_draw.c:278: vbo_exec_vtx_unmap: Assertion `exec->vtx.buffer_ptr != ((void *)0)' failed.
Aborted

or

...
LOG: 0 Started Mode PickPoints
Segmentation fault

I've seen both of these errors. The first one happened on small files (Kb level) the second one happened on larger files (Mb level)

I had the same problem. The work around was simple:
Switch to "Points" render mode before clicking on the "PickPoints" button.
Render -> Render Mode -> Points
