<h1>20070809 - Graphics Engine Videos</h1>
|
||||
<br>
|
||||
|
||||
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 <a href="http://ffmpeg.mplayerhq.hu/">FFmpeg</a>, 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.
|
||||
<br>
|
||||
<br>
|
||||
<strong>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.</strong>

<strong>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.</strong>
|
||||
<br>
|
||||
<br>
|

<strong>And please don't Slashdot this!</strong>

<b>First Just Motion</b>
|
||||
<br>
|
||||
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.

<b>Healing</b>
|
||||
<br>
|
||||
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.

|

<b>Telephoto</b>
|
||||
<br>
|
||||
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.

<b>Pushed Around</b>
|
||||
<br>
|
||||
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.

|

|
||||
<b>Complete Chaos</b>
|
||||
<br>
|
||||
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.
