True Axis creates a dynamic object to represent position and orientation of the world. This object is fixed at the origin with zero rotation.
When calling TA::DynamicObject::AddJoint with pOtherObject set to zero, the object is joined to the world. This joint will cause a collision to be generated. The other object in the collision will be the world object. In this case, calling IsWorldObject will return true. Otherwise, the return value will be false. |
