"It's been argued that simulations and computer-based models have proven to be the most powerful resources for advancing and applying math and science since the origins of mathematical modeling in the Renaissance."

- Roy Pea, Director of the NSF Funded SRI's Center of Innovative Learning Technology

The Astronomicon is a virtual 3-D modeling environment where learners can construct their own virtual models of the solar systems within the context of answering questions about the solar system. Thus, the goal is not to build a model of the solar system, but rather to build a model that will help you answer the question, "How many eclipses are possible in a year?" or "What would happen to the seasons if the earth had a 45 degree tilt?"

These questions will require learners to use NSF and NASA data and web resources both in creating their models and to explore design parameters.

In this environment, learners will construct models through our direct manipulation interface, will be able to explore fundamental science concepts in a more exhaustive manner, and will be able to collaboratively interact with other learners throughout the world via the Internet. The Astronomicon represents an exciting learning environment to use the power of cyberspace to learn about planetary motion.

As a work-in-progress, the Astronomicon is continually being enhanced, tested, and refined. The current features in the software (1.0.0.2) include:

• OpenGL graphics capable of running on any fully-compliant OpenGL graphics cards.


• Immersive 3D environment that allows users to grasp the awesome size of our Solar System.
  
• Sophisticated maneuvering user interface allows for easy navigation in the created solar system.


• Creation of planets with arbitary textures (either .bmp or .tga format), orbits, and other parameters.
  
• Unlimited shadowing from a single light source (the sun).


• Keplerian "physics".
  
• Full time control including stopping, time-stepping, time-rate variance, and date/time setting.


• "Drop" cameras allow the user to place cameras in space to watch events via two subviews.
  
• Orbit visualization through the use of multiply-colored, transparent disks.


• Peer-to-peer or client/server networking through the use of the patented Openskies Networking Technology (www.openskies.net)
  
• Zoom In / Zoom Out from 1/4 zoom (fish-eye lens) to x1048576 (2^20).


• Screen shots to the clipboard or to a Windows Bitmap (.bmp) file.
  
• Record/Playback capability that allows users to save their actions for future playback.
