Jul 6, 2014 · CGAL comes with quite a few demos and examples, looking at those (and then starting to modify them) is the best way to learn. windows. It all worked out fine, so I went on trying the recommended examples given in the file CGAL-5. For example, it is possible to apply Boolean set operations on objects that are the result of Minkowski sum computations. 3. Here is a list of all examples: Polyhedron/polyhedron2vrml. xz, which is provided here. Most CGAL packages explain which kind of kernel they should use or support. A dialog will pop up and you will have to choose what shall get generated. Such applications often take advantage of more advanced data structures: for example, Triangulated Irregular Networks (TIN) that can be the base for Digital Evelation Models (DEM) and in particular for the generation of Digital Terrain Models (DTM). 1 - Surface Mesh • All Classes Namespaces Files Functions Variables Typedefs Enumerations Friends Modules Pages C++ (Cpp) Bbox_2 - 8 examples found. cpp; The orthtree package changed to allow for custom data stored per node in the orthtree. provides an (even shorter) example in Polyhedron/draw_polyhedron. 2/make directory.
