Celestia To Do List ------------------- USER INTERFACE * More star label modes--nearest stars, brightest stars * Make picking more intelligent * Make picking more accurate for non-spherical bodies * Views of planet and satellite orbits * User control over which orbits should be displayed * Add preferences for text color to config file * Dialog box for displaying detailed information about a star or planet * Create a manual * Star browser: flag stars with planetary systems * Solar system browser: add icons * Popup H-R diagram window * Use a slider widget for controlling ambient light level * Allow precise control of FOV * Implement multiple simultaneous views, so that you can, for example, watch an eclipse simultaneously from the surface of the Earth and the Moon VISUALS * Get a real texture map for Eros * Non-Lambertian illumination functions for planets * Add haloes around bright planets similar to the ones around stars * Comets with dust and ion tails * Add some deep sky objects--planetary nebula, supernova remnants, etc. * Procedural textures for extrasolar planets * Bump mapped cloud layers * Make atmospheres work for oblate planets * Render galaxies with colors--bluish spiral arms, yellowish center * Render dark dust bands in galaxies * Add textures to Mir model * Cloud shadows POLISH * Tutorial mode * Add a flashy intro screen * Preload some textures to avoid loading delay * Use Greek letters in Bayer designations * Make the demo loop * Add a demo mode that visits random targets * Compute accurate altitude above oblate planets/stars using point-to-ellipsoid distance function. * Load add-ons from subdirectories of extras SIMULATION ACCURACY * Fix apparent magnitude calculation for planets * Figure out a way to estimate gas giant's radius given its mass * Use a better estimate for star radius * Make some attempt at calculating stellar rotation rates * Model the chaotic rotation of Hyperion * Double star systems: make the stars actually orbit each other * Account for the finite speed of light * Expand the galaxy database * Use more intuitive/standard fields in galaxies file--instead of axis/angle orientations, use 'angle from face on' etc. BUGS * Fix wobbling of planet shadow on rings when time is accelerated * Investigate possible visual anomalies with ring shadows on ATI Rage cards * Fix slowdowns with ring shadows and night textures on ATI Rage cards * Eliminate eclipse shadows from the dark sides of planets (only visible when ambient light level set to something other than 'none') OPTIMIZATION * Add option to force 16-bit textures * Add low resolution texture package CODE * Make parser more robust (and fix that EOF problem) * Change random printfs to DPRINTFs and Logs * Finish assert-ing the code PORTING * Bring UNIX UI up to level of Windows UI * Implement solar system and star browsers * Context menus for both GLUT and Gtk versions * Make bump mapping and other GL extension stuff work better on OSes other than Windows. * Use OpenGL 1.4's vertex program extension MISC * Create more powerful scripting system * Make solar system creation applet, for adding hypothetical systems to a Celestia universe * Switch to UNICODE * Internationalization
