Crash when try to compute the approximate proxy after region growing

[louhz]

Hi, Thanks for your great work! However, when i try to compute the approximate proxy after region growing , the system break and the following error drops:

21:05:19 INFO #vertices=9622 #triangles=19244 Failed to compute progressive hulls... Computed proxy with 56 vertices and 112 triangles Segmentation fault (core dumped)

I guess this error was raised since I set up two many points for grow region?

Hi, we have not encountered these errors for quite some time. Do you use the .exe or build from source? If these issues persist, we could provide a debug patch that would hopefully allow us to recreate your crashing conditions.

Is your selection rather simple or complex with elongated parts? In the latter case, as @Snosixtyboo said, we are aware of failing cases...

Hi, this error shows up again when i try to switch the operator visualization type from growing region to compute tetrahedron mesh, and the following error pumps

vertices=7926 #triangles=15832

After some experiments, I realize that the error only pumps when I use the Scribble-based selection and the point selection is very sparse.

So my system setup is ubuntu 20.04 + rtx3090 and I am using build from source.

Hi, we found two issues where the code may try to use an uninitialized pointer. This may have been the issues that you saw, our fixes are in the hanging_issues branch and we will merge into the main and recreate the executables after a code review.
