LOD scheduling priorities are allocated by visibility and distance.
Images show agent autonomy. Agents in the field of view and near the camera act independently. Agents off camera are controlled by group leaders.

Xti is the global transform of bone i at time t.
X-refi is the inverse global transform of the bone in the reference position.
vref is the vertex in the reference position.
A 2D billboard from different views can be generated dynamically.
Billboards can be used to dramatically increase crowd size.
