This folder contains a number of sample programs that illustrate the core functionalities of CinoLib. To compile them you must download CinoLib on your machine, open a terminal in its main directory and type
cd examples
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make
Cmake will automatically detect and download the necessary external libraries (e.g. Triangle, Tetgen). You can selectively enable/disable external dependencies directly from the CMakeLists.txt file. At the end of the process, all the executables will be positioned in the newly generated bin folder.

Upcoming examples
Maintaining a library alone is very time consuming, and the amount of time I can spend on CinoLib is limited. I do my best to keep the number of examples constantly growing. I am currently working on various code samples that showcase other core functionalities of CinoLib. All (but not only) these topics will be covered:
Copy/paste points of view from the GL canvas for accurate visual comparisons and fast snapshot reproduction
Customize data structures with user defined mesh/vertex/edge/polygon/polyhedron attributes
Navigate application history exploiting Cinolib undo/redo facilities
Generate, process and visualize scalar fields
Generate, process and visualize vector fields
Topology editing operators for tetrahedral meshes
Topology editing operators for general polygonal meshes
Topology editing operators for general polyhedral meshes
Subdivision schemas for hexahedral meshes
Solve multi-labeling problems on surfaces and volumes using the GraphCuts wrapper
Integral curve computation (and tessellation)
Processing of 2D polygons (booleans, thickening), using the Boost Polygon Library wrapper
Compute the Medial Axis Transform (MAT) and Scale Axis Transform (SAT) of binary images using Qgarlib
