RayCollisionModel

Context: Sofa.Component.Collision.Geometry

Collision model representing a ray in space, e.g. a mouse click

Data:

  • name : object name

  • printLog : if true, emits extra messages at runtime.

  • tags : list of the subsets the objet belongs to

  • bbox : this object bounding box

  • componentState : The state of the component among (Dirty, Valid, Undefined, Loading, Invalid).

  • listening : if true, handle the events, otherwise ignore the events

  • active : flag indicating if this collision model is active and should be included in default collision detections

  • moving : flag indicating if this object is changing position between iterations

  • simulated : flag indicating if this object is controlled by a simulation

  • selfCollision : flag indication if the object can self collide

  • proximity : Distance to the actual (visual) surface

  • contactStiffness : Contact stiffness

  • contactFriction : Contact friction coefficient (dry or viscous or unused depending on the contact method)

  • contactRestitution : Contact coefficient of restitution

  • contactResponse : if set, indicate to the ContactManager that this model should use the given class of contacts.

Note that this is only indicative, and in particular if both collision models specify a different class it is up to the manager to choose.

  • color : color used to display the collision model if requested

  • group : IDs of the groups containing this model. No collision can occur between collision models included in a common group (e.g. allowing the same object to have multiple collision models)

  • numberOfContacts : Number of collision models this collision model is currently attached to

  • defaultLength : The default length for all rays in this collision model

Links:

  • context : Graph Node containing this object (or BaseContext::getDefault() if no graph is used

  • slaves : Sub-objects used internally by this object

  • master : nullptr for regular objects, or master object for which this object is one sub-objects

  • previous : Previous (coarser / upper / parent level) CollisionModel in the hierarchy.

  • next : Next (finer / lower / child level) CollisionModel in the hierarchy.

  • collisionElementActiver : CollisionElementActiver component that activates or deactivates collision element(s) during execution
