His email - treaves (@) silverfieldstech.com For this task you need knowledge about OpenGL, geometry and astronomy. Right now Stellarium displays comets like rocky body (as asteroids) without his tails. This correct display for comets who has long distance from Sun. But when comet moved near the Sun it have a two tails - dust and gaseous. You need calculate direction, size and brightness for this tails for each comets and render it on the Stellarium's sky. Mathematical model for comet tails you can found via NASA ADS. For starting points for understanding comet tails and its simple model you can read this: http://en.wikipedia.org/wiki/Comet http://en.wikipedia.org/wiki/Comet_tail http://adsabs.harvard.edu/full/1961ApJ...133.1091B -- With best regards, Alexander ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Stellarium-pubdevel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/stellarium-pubdevel
