Hello, my name is Leonardo Pessanha and i work at the Computational Methods and Engineering lab at COPPE-UFRJ in a scientific visualization project and i've facing some problems dealing with immesive paraview
I am working in a Windows 7 - 64 bit environment I've compiled paraview 4.0.1 with qt 4.8.2 - Microsoft MPI (4.2.4400.0) - vrpn 7.31 using VS2008 My stereoscopic system is passive and i am using the --stereo-type=SplitViewportHorizontal flag My tracking system is from ARTrack, and so far, i am only interested in the wand interactions, letting the headtracking for later First, i would like to know if there's any major changes/fixes in the immersive part of paraview from the 4.0.1 to the 4.2.0 that justifies a new compilation. It would be positive? After setting up the server and loading the VRPN plugin I've succeeded adding the grab interaction with the Model Transform Matrix but i had some obstacles It took me a while to understand that my center of rotation was 0 , 0 , 0 - and i would like to know if there's a way of changing that. My data is usually VTK Structured_Point and the format uses the 0 , 0 , 0 as the lower left point of the data, so it would be useful to change the center of rotation to the center of the object. ------------ Sometimes while doing translation i have a weird flickering movement that i've managed to control using the TrackerTransform value 1 0 0 1 0 1 0 1 0 0 1 1 0 0 0 1 I don't know why it worked, and i don't know why it doesn't work changing some of the matrix values, so i would like to understand a little better since i am a little blind in that aspect ------------ Right now i am trying to find a solution on the model illumination. I don't know why but only the backface of my model is illuminated. It's like the illumination camera position does not change at all, only the view camera. A way around that is flipping the normals but it does not solve my problem since only a part of the model is affected by the flip ------------ I've read in the participants page that the ARL contributed with the CAVE display. It would be a good idea to contact them? I would be glad to share more details if it's needed. I would really appreciate if someone could help in any of this aspects. Thanks in advance Leonardo Pessanha, LAMCE-GRVa/COPPE/URFJ
