Property Details

InertiaTensorScale public_oe static_oe property

Value to scale any created entities' inertia tensors by. Larger tensors (above 1) improve stiffness of constraints and contacts, while smaller values (towards 1) are closer to 'realistic' behavior. Defaults to 2.5.
public static float InertiaTensorScale
return float

NumberOfSamplesPerDimension public_oe static_oe property

Number of samples the system takes along a side of an object's AABB when voxelizing it.
public static int NumberOfSamplesPerDimension
return int
