Collision node tooltip: [X3DGroupingNode,X3DSensorNode] Collision detects camera-to-object contact using current view and NavigationInfo avatarSize. Collision is a Grouping node that reports collision detection for its children.
- Hint: Collision can contain a single proxy child node for substitute collision-detection geometry. Improve run-time performance by using proxy with simpler contact-calculation geometry.
- Hint: proxy shapes are not rendered and remain invisible.
- Hint: apply containerField='proxy' to uniquely identify the proxy child Shape or grouping node.
- Warning: PointSet, IndexedLineSet, LineSet and Text are not collidable geometry do not trigger collisions.
- Hint: NavigationInfo types '"WALK" "FLY"' support camera-to-object collision detection.
- Hint: content must be visible to be collidable and to be pickable.
- Hint: insert a Shape node before adding geometry or Appearance.
