CGoGN_3

CGoGN is a C++ library that provides:

• an implementation of several mesh data structures (with a versatile cells attributes mechanism):
  • combinatorial maps (1D, 2D, 3D)
  • graphs (1D)
  • incidence graphs (1D, 2D)
• several geometric modeling and geometry processing algorithms (mostly generic w.r.t. the underlying data structure):
  • surface remeshing, subdivision, decimation
  • surface geometry filtering, curvature computation
  • surface skeleton extraction
  • surface deformation
  • convex hull
  • hex mesh generation
• an ImGui interface with modules and signals
• openGL rendering for points, lines, surface, volume meshes

Building CGoGN

• create a build directory and go into it
• run cmake <cgogn_path>
• you can specify build type (and other options) by modifying CMAKE_BUILD_TYPE either by using cmake-gui or ccmake, or by specifying -DCMAKE_BUILD_TYPE="" when running cmake

LINUX and MacOS

make -jN (N being the number of threads) in the build directory

Windows

VS 2013 or better required
