We use VTK in a CAD Application and<br>> decided to move from version 4.4 to the latest release, which is 5.4.2 at<br>> this time. So I downloaded the sources, made a VS2008 solution with Cmake<br>> and built the libs and dlls. Besides replacing some deprecated methods I did<br>> not have to change anything in our code. No compiler-warnings, no errors (of<br>> course).<br>><br>> When I tested version 5.4.2 against 4.4 I found out, that 5.4.2 takes about<br>> 3-4 times
longer to visualize a 3d-model of some robot-arm than version 4.4<br>> did. The rendering while interacting is also very, very slow. Can anybody<br>> confirm such a performance drop? If so, then I think we might stick to v4.4<br>> a little longer, if not, then I'll have to figure out what went wrong in my<br>> tests.<br>><br>> Thanks<br>> Martin<br>> _______________________________________________<br><span>> Powered by <a target="_blank" href="http://www.kitware.com">www.kitware.com</a></span><br>><br>> Visit other Kitware open-source projects at<br>> <a href="http://www..kitware.com/opensource/opensource.html" target="_blank">http://www..kitware.com/opensource/opensource.html</a><br>><br>> Please keep messages on-topic and check the VTK FAQ at:<br>> <a href="http://www.vtk.org/Wiki/VTK_FAQ" target="_blank">http://www.vtk.org/Wiki/VTK_FAQ</a><br>><br>> Follow this link to subscribe/unsubscribe:<br>>
