OptionalcullPost a cull pass only every Nth camera-movement event, bounding worker traffic during continuous camera motion.
A trailing pass runs once movement settles, so the resting frame is culled
for the camera's final position. Defaults to 5.
OptionalsolidMinimum on-screen solid angle, in radians, below which an object is culled.
The test is resolution-independent: an object is culled when
asin(boundingRadius / distance) is smaller than this. Set to 0 to keep
frustum culling only. Defaults to 0.004.

All fields are optional; the defaults are chosen for AECO/BIM scenes.
