Mesh Boolean operation possible?

[liuzhy71]

Hello,

Is there any way that I can implement mesh Boolean operations with the binding similar to the CPP version?
I did not find any function that is similar to corefine_and_compute_union.

I just added them in 87cae94

I just added them in 87cae94

With this new functionality, the make failed on my PC.
The error messages are:

I guess you are using CGAL 5.0.x. It is no longer supported but I've updated the code anyway. It should be working now.

[liuzhy71]

Yes. I'm using CGAL 5.0.2. And thank you for the timely reply!!!
