```
public class UniversalJoint
extends JointBase
implements CopyableComponent
```
Implements a 2 DOF rotary joint, which allows frame C to rotate with respect to frame D by a rotation roll about the z axis, followed by a rotation pitch about the rotated y axis. All rotations are counter-clockwise.
The roll and pitch angles are available (in degrees) as properties which can be read and also, under appropriate circumstances, set. Setting these values causes an adjustment in the positions of one or both bodies connected to this joint, along with adjacent bodies connected to them, with preference given to bodies that are not attached to ``ground''. If this is done during simulation, and particularly if one or both of the bodies connected to this joint are moving dynamically, the results will be unpredictable and will likely conflict with the simulation.

public UniversalJoint()

    Creates a UniversalJoint which is not attached to any bodies. It can subsequently be connected using one of the setBodies methods.
  - UniversalJoint
```
public UniversalJoint(UniversalJoint.AxisSet axes)
```
  - UniversalJoint
```
public UniversalJoint(RigidBody bodyA,
                      RigidTransform3d TCA,
                      RigidBody bodyB,
                      RigidTransform3d TDB)
```
    Creates a UniversalJoint connecting two rigid bodies, bodyA and bodyB. If A and B describe the coordinate frames of bodyA and bodyB, then TCA and TDB give the (fixed) transforms from the joint's C and D frames to A and B, respectively. Since C and D are specified independently, the joint transform TCD may not necessarily be initialized to the identity.
    Specifying bodyB as null will cause bodyA to be connected to ground, with TDB then being the same as TDW.
    
    Parameters:
    
    bodyA - rigid body A
    
    TCA - transform from joint frame C to body frame A
    
    bodyB - rigid body B (or null)
    
    TDB - transform from joint frame D to body frame B
  - UniversalJoint
```
public UniversalJoint(ConnectableBody bodyA,

                      RigidTransform3d TCW,
                      RigidTransform3d TDW)
```
    Creates a UniversalJoint connecting two connectable bodies, bodyA and bodyB. The joint frames C and D are located independently with respect to world coordinates by TCW and TDW.
    Specifying bodyB as null will cause bodyA to be connected to ground.
    
    Parameters:
    
    bodyA - body A
    
    bodyB - body B (or null)
    
    TCW - initial transform from joint frame C to world
    
    TDW - initial transform from joint frame D to world
  - UniversalJoint

public UniversalJoint(ConnectableBody bodyA,
                      ConnectableBody bodyB,
                      RigidTransform3d TDW)
```
    Creates a UniversalJoint connecting two connectable bodies, bodyA and bodyB. The joint frames D and C are assumed to be initially coincident, so that roll and pitch will have initial values of 0. D (and C) is located by TDW, which gives the transform from D to world coordinates.
    
    Parameters:
    
    bodyA - body A
    
    bodyB - body B
    
    TDW - initial transform from joint frames D and C to world
  - UniversalJoint
```
public UniversalJoint(ConnectableBody bodyA,
                      RigidTransform3d TDW)
```
    Creates a UniversalJoint connecting a single connectable body, bodyA, to ground. The joint frames D and C are assumed to be initially coincident, so that roll and pitch will have initial values of 0. D (and C) is located by TDW, which gives the transform from D to world coordinates.
    
    Parameters:
    
    bodyA - body A
    
    TDW - initial transform from joint frames D and C to world

```
public void updateBounds(Vector3d pmin,

```
    Description copied from interface: IsRenderable
    
    Update the minimum and maximum points for this object. In an x-y-z coordinate system with x directed to the right and y directed upwards, the minimum and maximum points can be thought of as defining the left-lower-far and right-upper-near corners of a bounding cube. This method should only reduce the elements of the minimum point and increase the elements of the maximum point, since it may be used as part of an iteration to determine the bounding cube for several different objects.
    
    Specified by:
    
    updateBounds in interface IsRenderable
    
    Overrides:
    
    updateBounds in class BodyConnector
    
    Parameters:
    
    pmin - minimum point
    
    pmax - maximum point
  - prerender
```
public void prerender(RenderList list)
```
    Description copied from interface: IsRenderable
    
    Called prior to rendering to allow this object to update the internal state required for rendering (such as by caching rendering coordinates). The object may add internal objects to the list of objects being rendered, by calling
    list.addIfVisible (obj);
    for each of the objects in question.
    
    Specified by:
    
    prerender in interface IsRenderable
    
    Overrides:
    
    prerender in class BodyConnector
    
    Parameters:
    
    list - list of objects to be rendered
  - render
```
public void render(Renderer renderer,
                   int flags)
```
    Description copied from interface: IsRenderable
    
    Render this object using the functionality of the supplied Renderer.
    
    Specified by:
    
    render in interface IsRenderable
    
    Overrides:
    
    render in class BodyConnector
    
    Parameters:
    
    renderer - provides the functionality used to perform the rendering.
    
    flags - flags that may be used to control different aspects of the rendering. Flags are defined in Renderer and currently include Renderer.HIGHLIGHT and Renderer.SORT_FACES.
