Gramy Mafia II by matrixserek

13 mins of gameplay sequences from upcoming Mafia 2 title, Chapter 9 “Ball & Beans” (initial version is available at tvgry.pl). As you may notice from flowing character clothing and lots of dynamic particles – APEX effects are enabled.

Unity Bootcamp by Hemiogenic

Tech demo, developed by Aquiris for Unity 3.0 engine release. All physics is held by latest 2.8.3. version of PhysX SDK.

PhysX in Unreal by unrealop

Some new tests of PhysX SDK integration with Unreal 1 engine, we’ve mentioned it before.

3Impact Physx Force Field Test by gtxx

Scene consisting of 150 primitives, 1736 fluid particles and a forcefield – result of PhysX SDK implementation into 3Impact engine.

Weapon,Vehicle & pawn impact test by DigitalDemolition

Some more impressive, fully destructible environments in UDK.

According to developers, highlight for Unity 3 is cloth physics on arbitrary and skinned meshes – video of new cloth feature in action was uploaded to YouTube by one of Unity demo team members.

In addition, PhysX core was updated to version 2.8.3., collision layers and “thick” raycast were added.

Update: Another cloth test, with tearing | Cloth features overview from one of beta users

Update #2: official presentation of cloth feature

Update #3: Release notes

• Cloth and clothing simulation: use the new InteractiveCloth, SkinnedCloth and ClothRenderer components.
• Layer based ignore collisions: use the Physics inspector or Physics.IgnoreCollision().
• Continuous collision detection, to make sure that fast moving colliders will not pass through other colliders. See Collider.collisionDetectionMode.
• Added Physics.SphereCast() and Physics.CapsuleCast() to implement volume raycasts.
• Added Rigidbody.SweepTest() to check if a Rigidbody would collide with anything if moved into a certain direction.

Keep an eye on beta preview thread for further details.

BSG Viper Test in Unity3d/PhysX by imjinc2k

Colonial Viper fighter from Battlestar Galactica. Realistic space flight simulation with maneuvering thrusters.

rayfire tool by QbickSan

Nice and clean destruction sim using RayFire Tool and PhysX solver.

Cellfactor Revolution PhysX Demonstration by MCFiete

Cellfactor: Revolution – half-baked and thus failed killer-app for Ageia PPU. Today you can even play it fine on fast CPU.

Hybrid physx ON in metro2033 @level “Frontline” by tripkj

Another video from Metro 2033, running on Hybrid system (HD5850 + 8600GT) with Advanced PhysX effects. Same level, but without help of dedicated PhysX GPU and, thus, degraded performance – here

Internal physics system in Unity is using custom driverless version PhysX SDK – unfortunately, since main SDK core is very old (2.5, afair), it’s missing not only recent updates and bugfixes, but some features like fluids, cloth, forcefields and even GPU-acceleration. While Unity Technologies were keeping PhysX un-updated for years in a matter of “combability”, such renovation was actually needed by developers.

And, finally – recent announce of long awaited Unity 3.0 engine promises not only iPad and Ps3 platforms support, deferred render, built-in lightmapping system and unified editors, but “major updates to Unity’s.. physics features“

No details were revealed, but Tom Higgins, Unity Product Evangelist, made a short sneak-peak

We are upgrading PhysX but will be saving the specifics until later, let’s just say it will have some juicy new features for sure!

We’ll try to keep an eye on this, so stay tuned.

Update: new details on PhysX features for Unity 3.0 beta
