OPTICS SCENES AND MOVIES MADE USING POVRAY
One of the most useful features of POVRAY is the great ease with which the scene may be animated. Any variable such as position or material or texture or brightness etc. may be varied. Three scenes of increasing complexity are shown below. Movies of the results of the modeling are shown below. It's advisable to download any that may be of interest, and play them off-line.
As observed earlier, if you'd like to try modeling the scenes yourself, it's necessary to have appropriate include files.
The path to these files in a separate folder should be placed in the pov.ini file. It's good practice to make separate folders for each of the scenes, say 'lazazoom', 'derotele', 'pandora' etc., and inflate the zip files to the appropriate folder.
Having constructed a scene in POVRAY, it is remarkably easy to animate virtually any part of it. Any attribute in the scene is simply tied to a 'clock' which is set internally and moves from 0 to 1. In the pov.ini file, one needs specify only the number of frames, from 1 to as many as you like. There are many applications which can then be used to concatenate the frames into a movie.
