Hi All, I'd like to say thanks to the mailing list, for the support you gave me! However, I'm fnished with the performance tests for now. All I needed to know, was if the performance is comparable to OSG, and I'm totally satisfied.
We (my Workgroup in the University of Cologne) will continue using OpenSG. So I won't let you off the hook that easily ;-) Thanks a lot again, Daniel On 30/03/07, Dirk Reiners <[EMAIL PROTECTED]> wrote: > > Hi Daniel, > > Daniel Wickeroth wrote: > > Hi, > > > > I updated my OpenSG last Wednesday and recompiled everything, before > > running the same tests again. > > > > Here are the results: http://vis.uni-koeln.de/FrameTests/Test5.htm > > > > The obj files load much faster now, and the performance is as good as > > it was before. > > That looks ok.
