placing a camera inside an explosion and maybe cutting out the interior gives nice skyboxes for spacegames (like http://sfz.schattenkind.net), see info below on how to generate such explosions/plasma effects

i suggest rendering stars onto the skybox ingame using dots or tiny billboards, this way they will look sharp even if the skybox is not ultra-highres.

random explosion generation

i made a php script that would generated random colormaps and some random turbulence parameters and let it render all night long, producing one explosion image after another, and keeping the sources for later high-detail rendering of the good ones.

this is kind of bruteforcing artwork with enough processor power =)

also there are a few php scripts in there for comfortable viewing and marking the good ones, but you'll have to adjust them a bit.

here are a few samples :

  • Explode2.jpg
  • Plasma.jpg
  • Exp 001770 000.jpg
  • Exp 002112 000.jpg

  • macro particles

i generated a few thousand of those, you can find them and their sourcefiles (in breed) here : http://ghoulsblade.schattenkind.net/files/pov/povray_exploder/
(these are hereby released under public domain)
(the best ones are in exploder_nice.zip, ca 20mb, sourcefiles (.pov) included)

possible uses :

  • macro particles for explosions (see sample above)
  • billboard-textures for energy/plasma weapon-projectiles
  • basis for skyboxes for nebulae-like scenes in spacegames (see above)
  • basis for explosion animations (animate __TURBSTART__, see http://www.ogre3d.org/tikiwiki/POVRay+Explosions)
  • as background billboard for halo/hilighting effects

  • some might look rather nice when used as spheremap or something like that in reflection effects
  • Rorschach test  ;)

random planet texture generation
