speeds.py

# Speeds and distances for the intuitive physics move-across scenes.

# Recorded by applying forces to objects in the Unity simulation environment
# and observing how they roll as Unity simulates their physical movement.

# Since neither the physics nor the floor change between scenes, the object's
# movement should remain consistent across scenes.

# The X distance the object moves at each action step (the distanceByStep) is
# needed to position the occluders so they properly hide implausible events.

# We've modified the friction values for different shapes (spheres, cylinders,
# wheeled objects) to ensure that they all roll at the same pace.

# To reiterate: the distanceByStep is ONLY USED to position occluders!
