Below was posted on Nvidia 3D vision forums...

3D on the PS3 requires the game developper to modify the game to integrate a stereo rendering engine. Sony cannot convert previous games like nvidia and other PC drivers do. Native support from the game is mandatory.
So far 2 games are already compatible (Invincible Tiger and Avatar), and sony announced that Superstardust HD (PS network title) will have a 3D update.
Over the past year, Sony showed many game tech demoes in 3D of high profile sony games like GT5 (prologue), Wipeout HD and Motorstorm, but everytime asked whether these games will get the 3D update, Sony systematically refused to make any announcement. So these games must be considered as Tech demoes only until properly confirmed. (it's a shame because all i'm waiting to buy a PS3 is Wipeout in 3D)

The current 3D on the PS3 is currently achieved by transmitting the image using the Texas Instrument DLP3D checkerboard pattern or an interlaced image for interlaced display.
The technique is identical to what nvidia 3D vision currently does for 3D ready DLP rear-projection TVs and Zalman monitors.

The new system that will be used with the new hdmi 1.4 TVs is different and allows more flexibility.

The game still needs a native rendering engine but it can render at any resolution it wants and does need to apply the DLP3D checkerboard, the game hands over the images to the new API provided though Sony's firmware upgrade. The console firmware then takes the left and right images and transforms them to the hdmi1.4 format called "frame packing" which transmits full resolution images at stereo720p 50HZ/60Hz (for games) or stereo1080p 24Hz (for movies).

The display recieves these images and applies whatever transformation it wants (upscale, interpolate frames, whatever) and displays the frames through whatever 3D technique it wants (it can be shutter glasses with DLP3D checkerboard pattern, shutter glasses with full resolution images, passive polarized setup or whatever other technique can be invented).

The Framepacking format is part of the hdmi 1.4 spec, but some updated hdmi 1.3 chips and plugs can also transmit them, which is why most of the 3DTVs shown at CES are 3D capable with the hdmi1.4 spec but still use hdmi 1.3 plugs (the hdmi 1.4 plug is larger to add a return audio channel and an ethernet network link though the hdmi cable). One of the features of the PS3 firmware update is to do this update. Not all hdmi 1.3 devices can do this update though.
