It is not just HyperText,
And it is more than HyperMedia.
Technology gives us HyperMultiMedia.


This is presented as a map of the 200 closest stars to our Sun. As it turns out, this places our closest star almost exactly in the center of this group. Position, size, and color are specified for each member. For a distance reference, I think the closest star is about 7 light years away.
I found the basic map at or near http://www.msc.cornell.edu/~houle/World3d and it ran fine. At the time I was looking for examples of luminosity and this was the help I needed. It was written in VRML 1.0. so I put it through VRCreator in hopes that I could convert to VRML2.0. This worked OK but dropped the emissiveColor property and then I had to edit it back into the file. The original map was static so I added a slow rotation and a distant viewpoint, making it somewhat easier to locate Sol. Of course the movement you see in this show has nothing to do with the actual motions of these bodies, either relative to each other, or to the galactic center. I am finding references for the official id, distance, color, and actual relative luminosity for each of the stars. Currently, I should list http://www.honeylocust.com/Stars/credits.html
as a possible source for the original.

Next I added a simple version of our Earth and Moon in a simple orbit oround the our Sun. Of couse even with this limited space the real scale is so immense that a way to provide technically accurate scaling is beyond me at this point. Please look at this from the various viewpoints.



Incidentally, here is a picture of the Sun taken on my last birthday.



What does luminosity or emmissiveColor mean to your presentation?

Let's discuss your application so I can show you how the HyperMultiMedia concept will add to it's success.
