geometry processing and shape analysis framework

Hi there 👋

I am a PhD(c) and Research Assistant at the University of Zurich, Switzerland. I obtained my MSc from the Fluminense Federal University, Brazil, and my BSc in Computer Science from the National University of San Agustín, Arequipa. I was an early-stage researcher in the EVOCATION innovative training network. My research interests cover the following topics: real-time ray tracing, point cloud graphics, multi-display and parallel rendering, geometry processing, and geometric deep learning, in addition to my ongoing interest in algorithms, data structures, graphs, computational geometry, and competitive programming.

how to fill holes of a mesh

how can I use your code to fill holes on a triangular mesh surface and close it in order to make the mesh appropriate for volume calculation?

Recomputing topleset for mesh with new source?

I am trying to compute geodesic distance for all n source vertices in a mesh. How can I avoid reloading the mesh from disk n times?

This is for one source vert, and it works great:

 che * mesh;
 mesh = new che_off(my_mesh_file);  // load mesh from disk

 size_t n_vertices = mesh->n_vertices();
 vector <index_t> source = { 0 };
 index_t * toplesets = new index_t[n_vertices];
 index_t * sorted_index = new index_t[n_vertices];
 vector<index_t> limits;
mesh->compute_toplesets(toplesets, sorted_index, limits, source);

However, for the next source vert (in a loop), the call to mesh->compute_toplesets segfaults unless I reload the mesh in the loop:

vector <index_t> source = { loop_index };
...
 // mesh = new che_off(my_mesh_file);     // reaload mesh -- without this line it segfaults
 mesh->compute_toplesets(toplesets, sorted_index, limits, source);

How can I avoid reloading the mesh each time? Does is have a member function that will reset the state of the instance so I can call compute_toplesets again without reloading the mesh?

Dependencies

would you please prepare a more precise tutorial about dependencies. for example, I can not find "fopenmp"?

Compilation instructions for one example platform

Suggestion: Could you add example commands to install the dependencies and get the binary compiled for a single example platform (e.g., some Ubuntu LTS version)? Just something like:

"Under Ubuntu 18.04, you could install the required dependencies with: apt-get install ...".

I would really like to give gproshan a try for our research, but I am not an expert in building C/C++ applications and I spend hours trying to compile it and have not succeeded yet. I tried different Linux versions, but there always seems to be some library or compiler version wrong, a dependency missing, or whatever.
