AsymptotesShow the locations where the probability goes to zero.
Translucence and Index of RefractionSometimes you can see the orbital structure better if the orbital is partially clear.
AnimationsCreate AVI files or sequences of TIF, PPM, or BMP files.
StereoRed-blue (anaglyph), stereogram (SIRDS), stereoscope, LCD shutter glasses, Chromadepth, and overlay.
CutawaySee the interior of the orbital.

Orbital Viewer - News

14 September 2004: Orbital Viewer 1.04 released: the colors used in red-blue (anaglyph) stereo images can now be changed. The help file and manual have also been updated.

10 April 2002: Orbital Viewer 1.03 released: added output option for Digistar files.

8 October 2001: Rearranged the site slightly. I also switched web hosting companies, which means the old ~cprimus address will no longer work.

10 April 2001: Orbital Viewer 1.02 released: the program now prevents multiple copies from running, has a progress bar when compressing AVIs, and has two minor bug fixes. Plus there are some changes to the install program.

10 July 2000: Finally posted the examples from the manual.

11 April 1998: Orbital Viewer 1.01 released: two minor bug fixes. OV.PDF updated: minor typos fixed.
