• Use a set-based filesystem (instead of directory based). These would act like tags. Sets generated from predicates would also be handled by the filesystem (when used), for example ?modified>yesterday, ?size<1M. These could also include file extensions.

  vlc media,?modified>yesterday

  for files in the set 'media' which were modified since yesterday, and

Based on feedback from ChemicalR I'm cross posting all the things I've bookmarked in reguards to planet rendering here in the code forums. 

[url=http://www.gamasutra.com/view/feature/3098/a_realtime_procedural_universe_.php]Sean O'Neil[/url]'s 4 2001 part series is considered a foundation for realistic large scale (planets on up) rendering. Most of these methods are now obsolete and replaced with faster methods and gpu shaders. His [url=http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter16.html]atmospheric scattering[/url]method is still used often due to its relative simplicity, but it only produces earth atmospheres.

[url=http://acko.net/blog/making-worlds-1-of-spheres-and-cubes/]Steven Wittens[/url] 2009 multipart series is frequently linked to as I've searched for best practices in creating planets using modern methods. It is based on a cube with mesh texture and normalizes the vertex points into a sphere. The advantage to this method is that conventional terrain LOD methods, often used in first

In irc there was talk about FTL and the assorted gameplay issues with each method. Then I started thinking about other design and story issues trillek is having. Then I started thinking about my space game I haven't touched in a while.

A few years ago I saw a video similar to this one http://vimeo.com/40234826 and I was really struck by saturn's moons. Saturn has over 70 moons. That is a lot of surface area to explore and with assorted orbits around each moon, and saturn itself, that is a lot of gamespace. I also saw this picture http://misc.oranse.net/misc/wallpaper/earth.jpg taken from low Earth orbit and how amazing our planet looked from low orbit. I started designing a game with the setting of just our solar system that takes place during humanity's expansion into our solar system.

What if we used that setting, or a similar one, instead? What if trillek takes place in one solar system?

Using our solar system as a model: There are 4 terrestial planets. 4 gas giants. At least 4 dwarf planets and a numbe
