Hmm, you get this when you launch the application? Or is there a specific mesh you are loading?
I get it when ever load a mesh, i have tried it with various meshes including those in the input file
Hi, I have the same issue on Ubuntu as well. This seems to be a bug in CHOLMOD when it is compiled with MKL BLAS and OpenMP (see here: https://github.com/DrTimothyAldenDavis/SuiteSparse/issues/108).
In my case the "not positive definite" message only appears when using the "Supernodal" algorithm. If I replace
common.supernodal = CHOLMOD_SUPERNODAL;
with common.supernodal = CHOLMOD_SIMPLICIAL;
I can manage to solve the system. However, even in that case the resulting parameterization might be of a very poor quality with lots of self-intersections (see the attached screenshot on one of the test models)
With the latest changes, bff seems to run without any problems on Ubuntu 22 as long as suitesparse is installed on your system.
This is probably something I am doing stupid but after building the tool on Ubuntu I am getting the following error when using the viewer application.
When I use the command line I get no errors but the vt coordinates in the OBJ are all 0,0,0
