Get Visible Neighbors According To Social Groups

This compound provides you a list of actors that another actor can see. Therefore, it is necessary to define the field of view for an actor. Moreover, this compound supports the concept of social groups which make it easier to have different behaviors in one crowd simulation (see CrowdFX_Actor_SocialGroup.

Using the parameters in this compound, you can define the distance, height, horizontal view of actors, and how many actors in a group that you want to view.

Tasks: Crowds/Behavior

Output Ports:

Neighbor IDs — IDs of all visible Actors.
Neighbor Social IDs — Social IDs of all visible Actors.
Neighbor IDs outside own Social Group — Subset of the IDs from visible actors that are not belonging to the same social group as the current actor.
Neighbor IDs within own Social Group — Subset of the IDs from visible actors that are belonging to the same social group as the current actor.

Horizontal View	Horizontal eyesight of an actor. For humans, it is nearly 180 degrees.
Max Distance	Limits the distance in which an actor can see another actor. All actors further away than this distance cannot be seen by an actor.
Actor Height	The height of the actors eyes above the ground.
Max Number Points to Query	Maximum number of points to query for proximity information.
Max Number Points to See	Maximum number of points to store as neighbors.
Use Visibility Test	Turn on this option, if you want the actors to consider walls and the terrain when trying to spot other actors. When turning this option off, the actors can see other actors through walls and terrains.
Obstacles	Connects more geometries such as walls that can block the actors eyesight.
