SelectionVisualizer

Page Summary

SelectionVisualizer is an interface used to provide visual feedback when a BaseTransformableNode is selected in Sceneform.
It offers two main methods: applySelectionVisual to add a visual indicator when a node is selected, and removeSelectionVisual to remove the indicator when the node is no longer selected.
A known subclass, FootprintSelectionVisualizer, provides a concrete implementation by rendering a footprint beneath the selected node.
