X3D Reference



CollisionCollection holds a collection of objects that can be managed as a single entity for resolution of inter-object collisions.

The CollisionCollection node belongs to the RigidBodyPhysics component and its container field is collider. It is available since X3D version 3.2 or later.



SFNode [in, out] metadata NULL

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

SFBool [in, out] enabled TRUE

Enables/disables node operation.

MFString [in, out] appliedParameters "BOUNCE"

Default global parameters for collision outputs of rigid body physics system. Contact node can override parent CollisionCollection node. Selectable values for array: "BOUNCE" "USER_FRICTION" "FRICTION_COEFFICIENT-2" "ERROR_REDUCTION" "CONSTANT_FORCE" "SPEED-1" "SPEED-2" "SLIP-1" "SLIP-2".


BOUNCE: bounce value is used; USER_FRICTION: apply user-supplied value; FRICTION_COEFFICIENT-2: apply frictionCoefficients values; ERROR_REDUCTION: apply softnessErrorCorrection value; CONSTANT_FORCE: apply softnessConstantForceMix value; SPEED-1: apply first component of surfaceSpeed array; SPEED-2: apply second component of surfaceSpeed array; SLIP-1: apply first component of slipFactors array; SLIP-2: apply second component of slipFactors array.

SFFloat [in, out] bounce [0,1]

Bounce indicates bounciness (0 = no bounce at all, 1 = maximum bounce).

SFFloat [in, out] minBounceSpeed 0.1

MinBounceSpeed m/s needed to bounce.

SFVec2f [in, out] frictionCoefficients 0 0

FrictionCoefficients used for computing surface drag.

SFVec2f [in, out] surfaceSpeed 0 0

SurfaceSpeed defines speed vectors for computing surface drag, if contact surfaces move independently of bodies.

SFVec2f [in, out] slipFactors 0 0

SlipFactors used for computing surface drag.

SFFloat [in, out] softnessConstantForceMix 0.0001

SoftnessConstantForceMix value applies a constant force value to make colliding surfaces appear to be somewhat soft.

SFFloat [in, out] softnessErrorCorrection 0.8

SoftnessErrorCorrection indicates fraction of collision error fixed in a set of evaluations (0 = no error correction, 1 = all errors corrected in single step).

MFNode [in, out] collidables [ ] [X3DNBodyCollisionSpaceNode,

Input/Output field collidables.



  • Contains an array of CollisionSpace, CollidableShape or CollidableOffset nodes (containerField='collidables').
