Hi Luigi, The GPU Volume Mapper of the VTKEdge have a very good quality and speed, but at this stage it have several bugs. I have submitted two of them in the bug-tracker on February (you can found it at: http://www.vtk.org/Bug/my_view_page.php , selecting VTKEdge as project), but until now I have received no support. However, VTKEdge is in alpha stage. I hope that before the first final release these bugs will be fixed. In anycase, please use the bug-tracker to post your bugs (don't forget to check other mappers, like the software raycaster, in order to make sure that these bugs are related to the GPU Volume Mapper)...
Good luck, Gianluca Arcidiacono IR&T engineering s.r.l. www.irt-engineering.it ________________________________ Da: Luigi Gallo <[email protected]> A: [email protected] Inviato: Mercoledì 3 giugno 2009, 14:55:20 Oggetto: [VtkEdge] Probable bug when dollying the camera Hi all, I'm testing some features of the GPU volume mapper. I found it really great, however I believe there is still a bug to solve. It happens when dollying the camera toward the volume. In greater details, it seems to happen when the camera enters the bounding box of the volume. At this link: http://www.luigigallo.net/errorGPUrendering.avi You can find a short video (2.19 MB) that shows what happens when dollying the camera. Inside the white rectangle you can see the volume as it is expected (I use the vtkVolumeRayCastMapper), outside the white rectangle you can see the distortion introduced by the vtkKWEVolumeMapper. You can easily reproduce the bug by using the vtkKWEVolumeMapper as volume mapper and vtkInteractorStyleTrackballCamera as interactor style (in particular, I used vtkDICOMImageReader to load a DICOM series). By moving up the mouse you will see a sudden "overdolly" of the camera.
