Phyz
From Wikipedia, the free encyclopedia
Phyz (Dax Phyz) is a public domain,[1] 2.5D physics engine with built-in editor and DirectX graphics and sound. In contrast to most other real-time physics engines, it is vertex based and stochastic. Its integrator is based on a SIMD-enabled assembly version of the Mersenne Twister random number generator, instead of traditional LCP or iterative methods, allowing simulation of large numbers of micro objects[2] with Brownian motion and macro effects such as object resonance[3] and deformation.

Description
Purpose
Dax Phyz is used to model and simulate physical phenomena, to animate static graphics, and to create videos, GUI front-ends and games. There is no specified correlation between Phyz and reality.[4]
Features
Source:[5]
- Deformable and breakable objects (soft body dynamics).
- N-body particle simulation.
- Rod, stick, pin, slot, rocket, charge, magnet, heat, actuator and custom constraints.
- Turing complete, real-time logic components (Phyz Logics).
- Explosives.
- Collision and break sound effects.
- Message-based application programming interface.
- Real-time, constraint-aware editing.
- Metaballics effects.
- Bitmap import.
- OpenMP 2.0 support.
Platform availability
Phyz requires Windows with DirectX 9.0c or later, a display adapter with hardware support for DirectX 9, a CPU with full SSE2 support, and 1 GB of free RAM.[6] The Metaballics effects require a GPGPU-capable display adapter.[7]

Screenshots
- Hammer scene (upper left; deformable objects): The hammer's centre of mass is displaced from its rotational axis, creating a torque which keeps the ruler from rotating.
- Wedge scene (upper right; breakable objects): How to make an impression.
- Yoda scene (lower left; bitmap import, metaballics): 3.446 vertices and 13.336 rods; the vertices form metaballs with colour information from a photograph of a clay model.
- Balloon scene (lower right; heat constraints): "Why am I lighter in the water?" Dax asked after a recent swimming lesson. Dax, like balloons, floats since there are more particles pushing on the bottom than on the top, as in buoyancy.
- Contained Air Burst (N-body particle system, soft body dynamics): 32.068 vertices, 35.283 constraints. After a brief mushroom formation, the semi-spherical shockwaves propagate to the rectangular container walls, where they are reflected, eventually forming a wedge shape in the middle, quickly degrading to a half-sphere under the influence of gravity.
