Digital Asteroid Models


Purpose

The digital asteroid models available on this page are in one sense the "final deliverable" from this research program. I make them available here for scientific research, educational, and private uses. In other words feel free to use these models for any non-commerical, non-profit use. Do not use them for any commerical purpose without written permission from Scott Hudson (toutatian@yahoo.com) and/or NASA.


Making Your Own Renderings

There is an excellent freeware 3D rendering package called "Povray" available at (www.povray.org). I have used it under the Windows 95/98, Linux, and HP-UX operating systems. It is also available for other systems. With this installed on your computer you can make 3D renderings of any of the models available below.

If you use renderings of these models in some public manner (e.g., on the web) please including the acknowledgement "3D asteroid model courtesy of Scott Hudson, Washington State University." I would also appreciate it if you would include a link or reference to these web pages.


Description

Each of the zip files should contain five files. For example, toutatis.zip contains the following files:
 
toutatis.obj This is the digital model in Wavefront/Alias OBJ format. There is a freeware program called "Crossroads" that will convert this into various other formats.
toutatis.pov This is a povray scene file. If you have povray installed on a Windows 95/98 system you need only double click on this file to begin rendering. (Read the Povray documentation for other operating systems.) You can play with the setting in this file to make your own customized renderings.
toutatis.inc This is the digital model in povray format (using the "smooth_triangle" contruct). It is read by "toutatis.pov" during rendering.
toutatis.ini This is a povray ini file containing a few parameters telling povray how to do the rendering. Your rendering might look funny if you don't tell povray to use this ini file.
toutatis.jpg This is an image of the rendered model. It's what you should get if you run povray on toutatis.pov.
