Collision

Collision detects camera-to-object contact using current Viewpoint and NavigationInfo avatarSize. Collision is a Grouping node that handles collision detection for its children. Collision can contain a single proxy child node for substitute collision-detection geometry. Note: proxy geometry is not rendered. Note: PointSet, IndexedLineSet, LineSet and Text do not trigger collisions. Hint: improve performance using proxy for simpler contact-calculation geometry. Hint: NavigationInfo types ''WALK' 'FLY'' support camera-to-object collision detection. Hint: insert a Shape node before adding geometry or Appearance.

id Name DataType PartType Default ValueType Description
MFNode addChildren MFNode inputOnly The addChildren event appends nodes to the children field of a grouping node. Any nodes passed to the addChildren inputOnly field that are already in the children list of the grouping node are ignored
SFVec3f bboxCenter SFVec3f initializeOnly 0 0 0 Bounding box center: position offset from origin of local coordinate system.
SFVec3f bboxSize SFVec3f initializeOnly -1 -1 -1 Bounding box size: automatically calculated, can be specified as an optimization or constraint.
MFNode children MFNode inputOutput Node field that contains a list of children nodes
SFTime collideTime SFTime outputOnly Time of collision between camera (avatar) and geometry.
SFBool enabled SFBool inputOutput TRUE Enables/disables collision detection for children and all descendants. Hint: former name quotecollidequote in VRML 97 specification.
SFBool isActive SFBool outputOnly isActive true/false events are sent when triggering the sensor. isActive=true when view-object collision occurs, isActive=false when view-object collision no longer occurs.
MFString logFeature MFString inputOutput state, child, parent, route, eventIn, eventOut controls the logging of changes, state: log state changes (e.g. live), child: log child add/remove, parent: log parent add/remove, route: log route add/remove; eventIn: log receiving of events, eventOut: log sending of events: guiView, runtime system should create node-view, guiEdit: runtime system should create node-editeverything: log everything
SFNode metadata SFNode inputOutput MetadataObject container for payload metadata inside MetadataSet element
SFNode proxy SFNode inputOutput alternate object to be checked for collision, in place of the children of this node.
MFNode removeChildren MFNode inputOnly The removeChildren event removes nodes from the children fieldof the grouping node . Any nodes in the removeChildren event that are not in the children list of the grouping node are ignored
SFBool render SFBool inputOutput TRUE Flag to control the visibility of the node or subtree
SFBool showBBox SFBool inputOutput FALSE Show Bounding Box of Subtree.
