20070809 - Graphics Engine Videos
++ +Until middle of September, my time is near 100% taken by my photography shows, but I did manage to grab an hour to modify the test mule to generate sequences of stills. +With help from FFmpeg, I can now post video. +The videos below are from the dummy test graphics engine. +They show what the engine can do, WITHOUT any time put into content creation. +
+
+070810 Update : Somewhat fixed the video color and quality issues by tweaking the compression parameters and adding 50% more bandwidth. +Had to undo the traditional "throw away the color and darks" video encoding policy. Here are my FFmpeg settings. +

+Yep, it is going to take a while to download (about 9MB per video), had to use 3Mbps to capture the motion, will need Quicktime to view movies on the page, +also provided MPEG4's see links. +
+
+And please don't Slashdot this! +
+
+First Just Motion +
+Slow motion, shows off the painters fractal compositing engine. Still using an 8bit framebuffer for this, moving to 16bit for HDR soon. +Also there are a few clipping issues to fix which might be noticeable in this example. +This entire test world is defined by a simple nested 18 cell rule, so it tends to look the same at any scale. +However, when finished, Atom will have over 100,000 nested cell rules defining the world, with unimaginable detail and structure at any scale. +

+ +Healing +
+Shows motion and the self healing of the world. Sorry, don't have the physics engine on, so the effect is a little static right now (not effecting surrounding objects, etc). +Areas that explode go red, then reform. After I finish my optimizations, all objects will be linked into CFD/physics engine, then this will truly be interactive. +

+Looking a the world from far away, then using a telephoto zoom. Shows the motion blur well, and how any amount of dynamic motion is no problem. +

+Pushed Around +
+This shows a little of the micro gravity effects in Atom. You are looking out at the rest of the world from a micro world switch is spinning relative to the rest of the world. +Then the player gets bumped, tossed, and spit out by another spinning sub-world. There is no limit to the number of nested worlds in Atom. +You could be inside an area which is spinning inside another area which is spinning inside another area ... pull out the barf bag. +

+ +Complete Chaos +
+Switched the healing to being very fast, to show some dynamic chaos. Atom does what no other engine does well, insane amounts of fully 3D dynamic motion. +
