Backwards Compatibility

For backwards compatibility reasons we provide a built-in legacy implementation that emulates the old API precisely. Please note that this is meant as a temporary measure which will eventually become naturally obsolete. For this purpose, this migration guide entry will describe moving from any older viewer version to 2.18 while using the legacy implementation

• Viewer or DebugViewer instances are replaced by LegacyViewer
• The hits field from SelectionEvent now holds the hit node and hit point.
  type SelectionEvent = {
    multiple: boolean;
    event?: PointerEvent;
    hits: Array<{
      node: TreeNode;
      point: Vector3;
    }>;
  };
  

• The synchronous loadObject was removed. Please use loadObjectAsync which works the same way
