By using FOX for the user interface of your application, your application can, in most cases, be ported across several platforms by a simple recompile. <p> Since FOX uses C++ for its implementation, it can be interfaced easily to existing libraries and applications written in C++, C, and FORTRAN as well as many other programming languages. <p> Therefore large, existing software packages may be given a modern user interface without performing a complete code rewrite. Moreover, through the FOX toolkit, such applications are then simultaneously available on <b>Microsoft Windows</b> as well as <b>Linux</b> and other <b>UNIX</b> systems, such as workstations from <a href="http://www.hp.com">HP</a>, <a href="http://www.sgi.com">SGI</a>, <a href="http://www.sun.com">SUN</a>, or <a href="http://www.ibm.com">IBM</a>. <p> The FOX toolkit library is freely available, without fees or royalties, subject to the <a href="license.html">Lesser GPL License</a>. However, in the course of incorporating the library into your application, you may find that you need various additional capabilities unique to your particular application, such as: <ul> <li>Custom, <em>one-of-a-kind</em> widgets which set your FOX application apart.</li> <br> <li>Building specialized extensions to FOX toolkit or interfacing FOX toolkit with other software packages.</li> <br> <li>Adding new features to the FOX library itself.</li> <br> <li>Porting applications to new platforms.</li> <br> <li>Aiding in porting applications to the FOX Toolkit.</li> </ul> <!--- TOPIC TITLE --> <p> <table width=100% cellpadding=0 cellspacing=2><tr><td width=100% valign=bottom id=HEADLINE><b> Technical and Engineering Software <br><img src='art/line.gif' width=100% height=1></b></td></tr></table> <p> <!--- TOPIC TITLE --> Many Engineering Software companies have chosen to adopt FOX because it works on big <b>64-bit</b> workstations. Software for these machines was historically developed using the <b>Motif</b> user interface. <b>FOX</b> has turned out to be a great replacement for Motif: while using many of the same concepts of layout managers, it is much more succinct and offers a larger, and more easily expandable, set of controls. <p> As a former Motif programmer myself, I estimate that it takes between <b>one tenth</b> to <b>one twentieth</b> the amount of code to construct user interfaces in FOX as compared to Motif. <p> Moreover, FOX offers finer control over layout placements and makes embedding icons in the user interface much simpler. Of course, it works on Windows, too... <p> A key feature in most Engineering Software is the ability to perform <a href="http://www.opengl.org">OpenGL</a> drawing. FOX offers a number of easy to use Widgets for this, allowing designers to draw geometry on the screen without having to learn about OpenGL camera and lighting models. <p> As an example, look at the CFD (Computational Fluid Dynamics) and FEM (Finite Element Method) <a href="screenshots/tux.jpg">visualization and analysis code</a> which was developed by CFD Research Corp. using the FOX Library. The image shows particle traces through a multi-zone, unstructured grid of an air flow problem around our favorite <a href="http://www.sjbaker.org/tux">mascot</a>. <p> I have been active in computer graphics and scientific data visualization software for many years, working on all aspects, ranging from writing special-purpose mini-programming languages to development of geometric and numerical algorithms. <p> <!--- TOPIC TITLE --> <p> <table width=100% cellpadding=0 cellspacing=2><tr><td width=100% valign=bottom id=HEADLINE><b> Contact Information <br><img src='art/line.gif' width=100% height=1></b></td></tr></table> <p> <!--- TOPIC TITLE --> <p> <pre> <img src='screenshots/contact.gif'> </pre> <!--- COPYRIGHT --> <p> <table width=100% cellpadding=0 cellspacing=0><tr><td width=100% valign=top id=HEADLINE align=right> <img src='art/line.gif' width=100% height=1><font size=-1> Copyright © 1997-2004 Jeroen van der Zijp</font> </td></tr></table> </p> <!--- COPYRIGHT --> </body> </html>
