Creating behavior scheduling bounds

• A behavior only needs to be scheduled if the viewer is nearby

  • The viewer's activation radius intersects its scheduling bounds

  • Behavior bounding enables costly behaviors to be skipped if they aren't nearby

• A behavior's scheduling bounds is a bounded volume

  • Sphere, box, polytope, or combination

  • To make a global behavior, use a huge bounding sphere

• By default, behaviors have no scheduling bounds and are never executed!

  • Common error : forgetting to set scheduling bounds
