Reactor (Havok)

From Wikipedia, the free encyclopedia

reactor is a physics engine from Havok software for use in discreet 3D Studio Max.

[edit] Overview

reactor ships with 3ds max, fully integrated, in Max versions 5 and up. reactor is often used for realistic physics simulation that would otherwise be unrealistic and take a large amount of time if animated by hand.

[edit] Dynamics types

reactor is capable of computing rigid body, soft body, cloth and rope collisions, and even all four types interacting with each other. A robust physics engine, reactor can handle several hundred rigid bodies interacting with each other without a problem on most computers. reactor can also simulate dynamics of any supported type interacting with a water volume, including adjustable viscosity and depth, among other things.

[edit] Forces and constraints

reactor includes a large number of forces that can be used in simulation, apart from the default gravity: springs, dashpots, motors, wind, fractures (breakable objects), even a "toy car" type, with definable body/axis/wheels. reactor also has many constraints available, including hinges, point-to-point constraints, prismatic constraints, car-wheel constraints, point-to-path constraints, and even ragdoll constraints to realistically simulate a lifeless body. In addition, reactor is compatible with Space Warp modifiers in 3ds max
