EWDraw is a powerful vector graphics ActiveX for 2D
and 3D visualisation and animation. You can use it for
CAD,GIS and others. The EWDraw is based on Open
CASCADE geometric kernel v 5.2 and openGL.
The library is realized as a run-time Windows 32 bit
OCX (ActiveX control). Either can be used with
applications written in the popular Visual IDE
languages such as Visual Basic, Delphi, C++ Builder ,
Visual C++, .NET and INTERNET
