A problem with realtime gpu rendering is that the antialiasing is too low for television or other high quality animation or movie produciton.

A simple solution is render out the images to larger multiple (quadruple or octagle) size of the original.

So if you want x2 or x4 for antialiasing for animations in realtime, amp your antialiasing in the video card in the setting to as far as it can go, then multiply the image size by such desired antialiasing multiplier before image export.

(720 px wide by 4 is 2880 px wide)

Then in a compositing software, resize the images to the original size, and like magic, you have antialising!

Attached is a test I did with random stuff, and I rendered the image to 5000 x 3375 (720 x 486 NTSC by 7, more or less) and compressed to it's original size, and enjoyed the quality. Each frame took no more than 2 or 3 seconds for truespace to write the file to the harddrive.
The antialiasing quality of the image is like 0 minimum to 3 max in most software. Not sure what the maths is.

I'd say... win.

thanks draise

Right on I use this technique every time

but why is the car coming out of the rhino's butt

Wow. Very nice clarity.
Thanks for sharing Draise!

lol, good question on the car coming out of the rhinos' butt! Also, the pharoah is.. not really helping. Ohwell, must be a subconscious thing I did there. =P lol

Butt or not butt, it kicks ass! Thanks a lot, your tip brings improvement to the supersampling feature.
