What is new in version 6.0
DG Kernel is considered a new product. Most features of KernelCAD are supported. See Porting to DGK.
Improved support for parametric modeling using expanded and improved interface, new examples and documentation
Interface set has been redesigned to simplify and make it uniform across all technologies. Old interfaces are supported also
New .mdg file format is better suited for future development. The previous .glm format is still supported. It is possible to convert glm to mdg and vice versa
In the new interface (DG Interface) Section term has been replaced with Entity to follow closer the industry standard. There is no separate SceneItem notion in v6.0
New Geometry concept allows isolation of internal geometry of an object from its role in model hierarchy and its 3D placement and orientation
Support for Wavefront .obj file format
Transient Boolean property allows excluding an entity from save operations
IEuclideanShortestPath_KC interface has been expanded.
The ESP sample demonstrates using shortest segments to define polygons on curved free-form surfaces. The curved segments stay on top, even if the surface is not convex. This provides a way to define 2D geometry on surfaces.
Redistribution has been simplified.
Rendering inside ClientDraw event handler is no longer supported.
It is recommended to use regular model entities to add auxiliary objects to the scene. Details.
New Console sample demonstrates using DGK component for geometric calculations in a command line application.
New Samples\NET\C#\Tests\ folder contains test applications which perform basic tests of interface methods not used in samples.
C++ samples have been converted to use smart pointers.
Model Explorer can be launched by pressing q key with focus on DGK window.
New methods of IMaterial allow customisation of color for parametric iso curves and wireframe meshes.
Display of normals turned on by Advanced > Normals in context menu is considered volatile short term and is switched off automatically on any model modification, model load and other events.
New DeviationFactor component context parameter allows adjustment of the deviation calculated at runtime by triangulation algorithm for surface presentation in special situations.
