Hi girls! An early version of the 96 particleSystem (4 per thruster) completely dynamic 'FlyerFrame' with all thrusters running (not normal in standard flight)... can be found here... http://urbanproductions.com/wingy/babylon/thruster/thruster10.htm . Zip file is there, too... just change the .htm to .zip and re-browse. This also has a new (s)ave camera views feature... for both of the cams in the demo, one arc, one free. It uses sessionStorage so it holds thru scene edits. Change it to localStorage object to save cam positions for MONTHS! Borrow those two funcs... just remove/workaround any refs to my GO object (global object). Look for funcs called storeCamLocs and loadCamLocs or similar. And may I say, even on my feeble machine... and even with 96 particle emitters running at once... we're still cookin'-fast. YAY! (Firefox 21) Not quite as smooth in IE11 though, for me. Generally (in game environment), there's only 4 thrusters operating on the flyer at any given time. No physics on the green particle sprayers yet... coming soon. No thruster controllers done yet either, also coming soon. Use 'c' key or button to toggle between the two cameras. The free cam starts badly positioned yet (bug). Just swing it around (and then hit 's' to store its position for further reloads if ya want). 't' or tracking button... toggles camera tracking. SHIFT-NUMPAD 2/8 will move the flyer up and down thru the scene... and do some fun particle trails. thruster02.js and flyerframe06.js... full of nightmare code... and so is the htm file. FUN! Lunar Lander, anyone?
