NVIDIA To Showcase PhysX Content

Early next week, NVIDIA will release the GeForce Experience Pack to demonstrate the 'PhysX' engine it bought from AGEIA earlier this year. The pack is free, and it will contain a stand-alone action game, maps for Unreal Tournament 3, and various demos. Gamasutra notes that the UT3 maps are "designed to 'fundamentally change' the game's mechanics."

From TFA:

The pack will feature NetDevil's Warmonger (pictured), a complete action game allowing players to use destructive powers to destroy walls, floors, and whole buildings to open new paths or close existing ones.

PhysX Matters in City of Heroes

[Bonker]

Both player super powers and quite a bit of Paragon City and the Rogue Isles have been designed or retrofitted for PhysX capabilities in mind.

For example, when a fire blaster sends a bad guy to the burn ward, bits of flame and whatnot fly around, catching on nearby terrain or even other players or enemies. The same things happen with electric and other blasters that have a big visual 'splash'.

My earth controller leaves lots of stones and pebbles lying around. Enemies, players, and my stone golem have to wade through these and kick them out of the way to get to where they're going. When her wind powers kick up, the rocks frequently roll around in the gusts.

Anyone who uses firearms in Paragon, Rhode Island or in the Rogue Isles generates LOTS of brass. If you're not careful, they'll pile up around your feet and go scattering when you walk around. If a flier-type happens to go around them, they'll be blown around by his wake.

Perhaps the most dramatic use of PhysX in player powers is the 'Propel' power. This allows some telekinetics and gravity control types to throw bits of the terrain around (summoned out of pocket-space, of course). It's frequently possible to litter a zone with 'Propel Junk', that you have to shove out of the way to get anywhere. It's quite a fantastic thing to knock out a gangster with a ballistic fork lift. Gravity control just does bad things to physics particles in general, such as spraying piles of the forementioned casing brass all over the place.

A flier who tears through a tree will see lots of leaves and maybe a branch or two swirl behind in his wake.

The real bonus to PhysX is ragdoll model physics. When you punt someone hard enough to send them flying, they often land... awkwardly. It takes a few seconds for a mook who's just been skipping along the pavement by his teeth to pull himself back together. A favorite bonus is to knock an enemy into a railing. You can often leave them helpless, hanging by their feet or even their head in some rare cases.

PhysX in City of Heroes uses the CPU-only dll by default, but will also work with an add on Aegia card or with the newer CUDA drivers from nVidia.
