Geometry Central

Geometry-central is a contemporary C++ library of information buildings and algorithms for geometry processing, with a specific give attention to floor meshes.

Options embrace:

A sophisticated floor mesh class, with environment friendly assist for mesh modification, and a system of containers for associating information with mesh parts.
Implementations of canonical geometric portions on surfaces, starting from normals and curvatures to tangent vector bases to operators from discrete differential geometry.
A set of highly effective algorithms, together with computing distances on floor, producing course fields, and manipulating intrinsic Delaunay triangulations.
A coherent set of sparse linear algebra instruments, based mostly on Eigen and augmented to mechanically make the most of higher solvers if obtainable in your system.

Pattern:

// Load a mesh
std::unique_ptr<SurfaceMesh> mesh;
std::unique_ptr<VertexPositionGeometry> geometry;
std::tie(mesh, geometry) = readSurfaceMesh("spot.obj"); 

// Compute vertex areas
VertexData<double> vertexAreas(*mesh);

geometry->requireFaceAreas();
for(Vertex v : mesh->vertices()) {
  double A = 0.;
  for(Face f : v.adjacentFaces()) {
    A += geometry->faceAreas[f] / v.diploma();
  }
  vertexAreas[v] = A;
}

For extra, see the tutorials. To get began with the code, see building. Use the sample project to get began with a construct system and a gui.

A introductory discuss on geometry-central was given at SGP 2020, test it out to get began: www.youtube.com/watch?v=mw5Xz9CFZ7A
