<p>Computation of mass properties for a rigid body actor. </p>
|
|
<p>To simulate a dynamic rigid actor, the SDK needs a mass and an inertia tensor.</p>

|
<p>This method offers functionality to compute the necessary mass and inertia properties based on the shapes declared in the <a class="el" href="classPxRigidBody.html" title="PxRigidBody is a base class shared between dynamic rigid body objects. ">PxRigidBody</a> descriptor and some additionally specified parameters. For each shape, the shape geometry, the shape positioning within the actor and the specified shape density are used to compute the body's mass and inertia properties.</p>

|
<li>
|
|
