public Vector3 inertiaTensor ;

Description

Диагональный тензор инерции массы относительно центра массы.

The inertia tensor is rotated by the inertiaTensorRotation. If you don't set inertia tensor from a script it will be calculated automatically from all colliders attached to the rigidbody. You can reset the inertia tensor to the automatically computed value by calling Rigidbody.ResetInertiaTensor.

// Expose tensor of inertia to allow adjustment from
// the inspector.

using System.Collections;
