Properties

aabb: magnum.Range3D get: Return the local axis-aligned bounding box (aabb) of this Rigid Object object. If the object is articulated, query could trigger aabb recomputation when state has been changed since the last query.
angular_damping: float get set: Get or set this Rigid Object’s scalar angular damping coefficient. Only applies to MotionType::DYNAMIC objects.
angular_velocity: magnum.Vector3 get set: Get or set this Rigid Object’s scalar angular velocity vector. Only applies to MotionType::DYNAMIC objects.
awake: bool get set: Get or set whether this Rigid Object is actively being simulated, or is sleeping.
collidable: bool get set: Get or set whether this Rigid Object has collisions enabled.
collision_shape_aabb: magnum.Range3D get: REQUIRES BULLET TO BE INSTALLED. The bounds of the axis-aligned bounding box from Bullet Physics, in its local coordinate frame.
com: magnum.Vector3 get set: Get or set this Rigid Object’s center of mass (COM) in global coordinate frame.

creation_attributes: attributes.ObjectAttributes get: Get a copy of the template attributes describing the initial state of this Rigid Object. These attributes have the combination of data from the original Rigid Object attributes and specific instance attributes used to create this Rigid Object.

handle: str get: Name of this Rigid Object

rolling_friction_coefficient: float get set: Get or set this Rigid Object’s scalar rolling coefficient of friction. Damps angular velocity about axis orthogonal to the contact normal to prevent rounded shapes from rolling forever. Only applies to MotionType::DYNAMIC objects.
