1. Putting Your World on the GeoWall: Building Content with Free and Common Software Chuck Anderson Center for Kinetics Analysis, Penn State University Teaching with New Geoscience Tools Feb. 10, 2008

2. “ Can we make our own GeoWall content?” - any administrator being asked to fund a GeoWall

3. Data that can be put on the GeoWall –Stereo-pair images and video –Surface topography with/without imagery –Object models –Molecular/mineral structures –Confocal microscopy –Volumetric data –CT data –Velocity data –Time series –In short, anything

4. Paths to the GeoWall –Stereo capable software –ArcScene, CrystalMaker, GEON IDV, VMD, Chime & Jmol –GeoWall software –Wallview, Immersaview, Walkabout –Free tools to create files for GeoWall apps –3DEM, MICRODEM –Common software to create files –PhotoShop, Illustrator, Dreamweaver –Visualization Toolkit (VTK) –www.vtk.org

5. VTK –Free open source visualization package –Works on Mac, Windows and all flavors of Unix –Object oriented programming model –Programmable in C++, Tcl/Tk, Java, Python –Stereo display on clone mode capable GeoWalls –Can output VRML models, stereo images and image sequences for creating stereo video –Not just for making GeoWall content
