1 ViSE integration in the VL zInteractive Simulation and Visualization zIntegration of ViSE in the VL zStatus, people involved and short term goals Virtual Laboratory meeting, July 3, 2001. Robert Belleman (

2 ViSE: goals in short zGeneric visualization tools yVL visualization workstation zInteractive Simulation yHuman-in-the-loop experimentation zApplied to a test case: ySimulated Vascular Reconstruction Interactive Dynamic Exploration Environment (IDEE)

3 Integration of ViSE in VL zTwo questions: yHow is data exchanged? yIn what format is data exchanged? Scanner, Simulation, Storage, Filter,... Interaction Visualization VL … moduleVL ViSE module !

4 Integration of ViSE in VL zAgreement (Sloot, Kaandorp, Belleman, Hendrikse, Groep, Belloum): yData Exchange: xGlobus Grid FTP if available xVLAM when available yData Format: xNetwork Common Data Format (NetCDF) (internationally excepted storage format for scientific data)... ViSE Vlab module !

5 NetCDF zExample NetCDF visualization (dataset provided by Gert Eijkel):

6 VL workstation hardware zCurrently installed yComputing and graphics hardware yStereoscopic 3D (5 pair of glasses) yOn loan: tracking (one sensor) zSoon: y6 DOF Wand and head sensor tracking yWand input device (buttons, joystick) yProjection setup (67” screen) Should be operational start of next month.

7 VL workstation software zSoftware installed: yCAVElib yPerformer yGlobus zSoftware ported from sgi/Irix CAVE: yVirtual Radiology Explorer (VRE) yGeometric Probes for Virtual Environments (GEOPROVE) ySARAnav
