3D Modeling : unit cells, crystals, surfaces and interfaces (4.0 version)
The 4.0 version allows of course the building up of crystals made of several thousands of unit cells. But also it is now possible to build up surfaces, grain boundaries and interfaces interactively with the help of graphic tools and 3D orientation of structures with the mouse.
More and more performed objects
Many interactive tools have been added to modify or create 3D representations of crystals (interactive bond and polyhedron searching, distance indications...).
During the construction of a 3D representation, a trace of all the modifications is kept and re-played for each building up. The (hkl) planes and the [uvw] directions are materialised and are used to orientate in a quick and precise way the crystallographic representations.
A powerfull "crystallographic builder" has been developed for the 4.0 version and crystallographic representations can contain thousands of objects without penalizing the rapidity of execution of the program.
