Physics

Physics (or dynamics) in SecondLife is implemented using the Havok physics engine.

A physical object may have no more than 32 prims. The minimum distance for objects to avoid collision (the spatial precision), is 0.1m (10cm)--and an error will occur if a prim/object is tried to be made physical but is within 10cm from another prim/object/avatar or the ground.

Vehicles are one application of the physics engine.

An object's physics flag, STATUS_PHYSICS, can be changed using llSetStatus or llSetPrimitiveParams and read back with llGetStatus and llGetPrimitiveParams.
