Hi
are there python bindings for this library?
Thanks for making Visilib available as open source and for all your work.
I am interested in calling Visilib from my program. While my program is open source, it is not GPL, and so it is not compatible with Visilib.
From what I can see so far, there are very few object-space 3D visibility libraries available -- do you know of any others?
I know Visilib uses CGAL (parts are GPL only, other parts are more permissive) and some other dependencies that may make changing licenses impossible. However, if it is possible, I would encourage you to consider that changing Visilib's license to LGPL would allow its use by more projects (open source and otherwise).
First of all, thanks for sharing this amazing piece of software. But I'm having problems compiling with exact arithmetic support because LEDA library is not available anymore.
The website at http://www.algorithmic-solutions.info/free/d5.php says
LEDA FREE EDITION IS NO LONGER DISTRIBUTED!
Is there any workaround for this? I can build and run the demo without exact arithmetic support though.
Platform:
Win10, Visual Studio 2022, x64 build (debug and release), without exact arithmetic libraries
To reproduce:
Launch visilibDemo.exe, press X to skip to the second demo: Two triangles and a large mesh.
The initial view is correct. Press "Space" to enable animation. I'm observing three cases:
Is that a bug, or a side-effect of non-exact arithmetic?
Demo crashes after scene changes.
Steps to reproduce:
Result:
Overflow detected: more than 200 recursive calls....
