Interactive 3D Modelling

Stereoscopic Shockwave 3D Prototypes Designed for the GeoWall

3D Interactive San Diego Fly Through (Windows only, ~14 Mb)
3dsandiego.exe is a standalone Windows executable that demonstrates some of the more advanced interactive features of Shockwave 3D for GeoWall technologies. This program runs in a 2048pixel by 700 pixel window. It assumes the desktop settings on your GeoWall system are set to 2048 x 768. In addition to the features described in the GeoWalldemo.exe program above, 3dsandiego allows the user to jump to any location in the 3d world, you can click objects and get detailed information about them, and the 3d world contains animated objects such as a car and jetliner.

Geowall Test file (Windows only, ~3 Mb)
Geowalldemo.exe is a standalone Windows executable that demonstrates some simple but potentially powerful interactive features of Shockwave 3D for GeoWall technologies. This test program runs in a 2048pixel by 700 pixel window. It assumes the desktop settings on your GeoWall system are set to 2048 x 768. There are unique features to this application that might be of interest to GeoWall users. The camera separation is retained no matter which direction you are looking. You may fly through the world and around objects and maintain the perception of 3D depth. Objects (in this case rotating boxes and particle systems) may be created with a simple mouse click. Camera separation may be varied between wide, medium, or narrow to enhance the 3D depth perception.

Animated VRML Files

Rayleigh Wave (~15 Mb): Rayleigh Waves are the most damaging waves caused by earthquakes. This animation illustrates the reverse elliptical dynamics underlying Rayleigh Waves that cause such intense shifting during an earthquake. This animation was developed for an educational video on earthquakes produced by SDSU Professor Dr. Pat Abbott and funded by the Seismic Safety Commission.

"Free-viewable" 3D Stereoscopic Examples

(Note: these applications can be viewed stereoscopically with the "free-view" technique, and it is only a matter of time before they are converted to the "widescreen" format for the GeoWall)

P53 Protein (Windows or Macintosh, ~3 Mb)
This example provides some additional navigation features, such as rotating the molecule. This program runs in a web browser on both Mac and Windows platforms with the Shockwave plugin. Stereoscopic representations serve a particularly useful purpose when confronted with complex 3-dimensional structure such as that found in organic molecules.

3D Interactive San Diego Fly Through (Windows or Macintosh, ~14 Mb)

Other Interactive Shockwave 3D Applications (Not Stereoscopic, Yet...)

	3D Interactive Mars Rover "Spirit" (Windows or Macintosh, ~2 Mb) Explore a 3D model of the Mars Rover "Spirit". Click parts of the Rover and learn more about them.
	3D Mars Tithonium Chasma Flythrough (Windows and Macintosh, ~5.5 Mb) Fly through the Tithonium Chasma on Mars. Contains a model of the Rover "Spirit". Also demonstrates the ability to turn terrain textured layers on and off.
	3D Mars Model (Windows and Macintosh, ~700 Kb)
	Real-time Southern California Earthquakes (Windows and Macintosh, ~2.85 Mb): This applications processes earthquake data from the past week and renders it in a 3D world with a shakemap of California. Users may click on spheres representing each quake to obtain more detailed information about the event.
	3D Earth Model (Windows and Macintosh, ~1.25 Mb) Includes a model of the Hubble Space Telescope.
	3D San Diego Watershed Flythroughs, developed for the Regional WorkBench Consortium. This is a series of interactive 3D models of the major watersheds of San Diego County. Two of the prototypes demonstrate the interaction between Shockwave 3D and QuickTime VR Panoramas (San Diego and Tijuana River Watersheds). A modified version of these flythroughs was created for Siggraph 2003's SigKids venue. These versions provide a little more user-friendliness and an option to query the digital elevation models for latitude, longitude, and elevation.
	3D SDSU Chemical Sciences Laboratory Building (Windows or Macintosh, ~3 Mb): Explore SDSU's newly completed Chemical Sciences Laboratory Building. This is the site of SDSU's Immersive Visualization Center, which will soon be incorporated into the model.
	DARPA Grand Challenge Autonomous Robot Competition Course (Windows and Macintosh, ~6 Mb ) This application demonstrates the ability of Shockwave to access latitude and longitude data in XML format from a web site, parse the XML, and animate objects navigating a terrain based on the lat/long data. We have also developed a version that interfaces with a MySQL database to access the same lat/long data. Simply a demonstration of the tremendous potential for data-driven interactivity in Shockwave 3D. Now, replay the DARPA Grand Challenge race!!
