Carbon Soft head demo, running in real-time, with real gravity on i7 3GHz. Created in Poser and then turned from a polygonal shell into a tetrahedral volume with the Carbon Volume Generator tool. 12,338 Tetras, 2 msec / frame = 6 million+ tetras/sec.
Self Colliding Cloth
Here is "Assassin" modeling a self-colliding dress and belt. This is a high resolution character model suited to animated movies or cut-scene previs. Cloth (15K triangles) colliding with the character mesh (64K triangles), not some fat cylinder representation. Simulation runs at 10 FPS

Here are 1500 spherical linear joints with huge load & real gravity. The mass of each box is the same - irrespective of its size. Spherical linear joints are like ball and socket with a radius. To test the joints a large force is applied to the root box. This is a demo you can't do with other popular physics engines, their joints will just blow up. Real gravity, no damping or freezing. Runs in < 1msec - i7 3GHz.
Hybrid demo with joints, rigid and soft bodies + cloth. There are 27,000 soft tetras in the truck tyres. The tyres are just a soft body on a rigid body centre. The wheel joints are prismatic linear + swing lock angular + soft linear servo joints. The ramp would give other physics engines a heart attack. It's held up with a single swing lock angular joint. The mass of the truck is huge compared with the ramp - 20x greater. The truck also has cloth sides and you can see the barrels roll into and stretch the cloth. There are also joints on the cab and the trailer. Real gravity. No damping or freezing. Runs in 9 msec. per frame i7 - 3GHz
A more complex rigid+soft body test scenario,with a chain of Rigid tori, rotating ground, a sheet of cloth and a chain of Soft cloth tori. This demo shows robust real-time simulation of a mix of object types – Rigids,and two kinds of soft objects – in challenging conditions, for example when the cloth sheet gets trapped between the soft chain and the rigid chain. Runs in real-time. All using real gravity.
"Soft" Suspension Bridge
The bridge is a challenging simulation due to the mass distribution and use of real gravity. In this demo we have 100 soft planks attached to 2 lower fibers, 2 upper fibers, and lots of side ropes also made of 16 subdivision fibers. The whole bridge holds nicely with only 8 solver iterations per frame. The ball is relatively heavy and deforms the planks as it rolls across the bridge. 7 msec per frame i7 3GHz.
Self-colliding cloth, running in real-time on i7 3GHz. Using real gravity, not some light weight value.
Soft Tetra Box
Pile of Tetrahedral boxes running in real time on an i7 3GHz. 1080 Tetras per box, 27,000 tetras total, with real gravity.
Note that the boxes are volume preserving and they settle into a very stable condition when they stop falling - no jitter. There are no freezing or other tricks, this is pure solver stability.
Gorgeous soccer net behaviour. Took us 3 hrs to set this up with Carbon, vs six months tweaking with a previous engine. Carbon is really easy to use because its very robust. Runs in 1 msec per frame, on i7 3GHz
