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

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

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

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) –

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
