Porting from SGI to Linux
OK, I’ve got the RWB VRX library working under Linux!
Eeeh? Say what?
The Responsive Workbench library with the Virtual Reality eXplorer!
We’ve got this Virtual Reality Workbench running on a SGI Onyx2, and one of our PhD students, Michal Koutek, wrote a library, based on SGI’s Performer, for building applications for this machine.
For making visualisations on our desktop pc’s we make much use of the Visualisation ToolKit (VTK).
Combining these two, Michal developed another library on top of the RWB library, called VRX, making it possible to use, for example, isosurfaces and streamlines generated in VTK, on the workbench.
Now, because the workbench is not really practical for developing applications, Michal created a simulator, with which to replay and test “real” workbench sessions.
My contribution has been the porting of all this software from SGI to Linux… and that’s not as easy as it looks, especially if you use the -Wall option of the compiler. The SGI compiler is soooo much more forgiving and less strict.
But I did it! I succeeded!
So now, I can write a VTK pipeline, convert the resulting vtkActor’s to pfGeode’s with vtkActorToPF, hang the whole shebang below the top node of the Performer scenegraph representing the virtual model of the workbench in the RWB simulator. And all that on my desktop pc running Debian!
Now let’s hope my programs are going to work on the REAL Virtual Workbench!
