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 0.1
m (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.
