Open CASCADE Version 4.0 Features Major Improvements and Is Now Available for Free Downloading

The Latest Version of these Open-Source 3D Modeling Components Includes

Advanced Data Exchange Capabilities, Improved Modeling Algorithms and A

Development Environment That Can Be Used for Working with Applications That

Are Non-Open CASCADE Dependent

    PARIS, Nov. 27 /PRNewswire/ -- The new Open CASCADE Certified Version 4.0
 has been thoroughly tested and documented and is now available for free
 downloading from the http://www.opencascade.com Web site.  This stable version
 incorporates many enhancements from both Open CASCADE developers and outside
 contributors; including corrections stemming from customer projects.  Open
 CASCADE Version 4.0 runs under Windows 2000 and Linux Intel 2.4, as well as
 under Windows NT/9x, SGI IRIX 6.4 and Sun Solaris 2.6.
     The new version is easier to install since code, binaries, samples and
 documentation can be downloaded either separately, as needed, or all at once.
 The software components can easily be compiled on a wide variety of platforms
 using standard open-source utilities (Automake, Autoconf).  With these
 utilities, a new user will be able to configure and compile the entire Open
 CASCADE package in two steps, thereby opening the door to a greater number of
 potential contributors.
 
     Outstanding features for data exchange, visualization, modeling and
       development
     One of the most attractive features of Version 4.0 is the availability of
 the Extended Data Exchange (XDE), Shape Healing and improved Sewing modules.
 They save time and allow obtaining high-quality results when importing
 geometrical data and solid model attributes.  XDE broadens the definition of
 data supported by the IGES and STEP exchange standards.  Shape Healing and
 Sewing enhance user productivity through the automatic correction and
 completion of imperfect or unsuitable data.  These modules are extremely
 useful for developing data exchange applications for CAD projects.
     For visualization tasks, new AIS 2D services allow the display and
 selection of two-dimensional graphic objects, while texture mapping can be
 added to views and shapes created with the Open CASCADE platform.
     Improvements in modeling algorithms include the resolution of 40 cases of
 topological singularities (defects in geometrical continuity) thanks to a new
 method for calculating shapes that ensures faster and easier treatment of each
 case.
     The WOK development environment, which enables groups of developers to
 work simultaneously on different products and optimizes utilization of the
 Open CASCADE components, can now be used to create all types of applications,
 even those that do not base development on Open CASCADE.
