public class BaseRigidBodyCollection
extends AbstractNode
implements VRMLRigidBodyGroupNodeType, VRMLChildNodeType
Implementation of the RigidBodyCollection node.
In this implementation, the sets of nodes for the bodies and geometry are not expected to change much, if at all. As such, arrays are used to represent the field values, rather than the more customary ArrayList that other classes use for MFNode fields The X3D definition of RigidBody is:
RigidBodyCollection : X3DChildNode {
MFNode [in] set_contacts [Contact]
SFBool [in,out] autoDisable FALSE
MFNode [in,out] bodies [] [RigidBody]
SFFloat [in,out] contactSurfaceThickness 0 [0,∞)
SFFloat [in,out] disableAngularSpeed 0 [0,∞)
SFFloat [in,out] disableLinearSpeed 0 [0,∞)
SFFloat [in,out] disableTime 0 [0,∞)
SFBool [in,out] enabled TRUE
SFFloat [in,out] errorCorrectionFactor 0 [0,1]
SFVec3f [in,out] gravity 0 -9.8 0
SFInt32 [in,out] iterations 10 [0,∞)
MFNode [in,out] joints [] [X3DRigidJointNode]
SFFloat [in,out] maxCorrectionSpeed -1 [0,∞) or -1
SFNode [in,out] metadata NULL [X3DMetadataObject]
SFBool [in,out] preferAccuracy FALSE
}
