API Reference > imodeljs-frontend > Tiles > TileBoundingBoxes TileBoundingBoxes Enumeration Options for displaying tile bounding boxes for debugging purposes. Bounding boxes are color-coded based on refinement strategy: Blue: A leaf tile (has no child tiles). Green: An ordinary tile (sub-divides into 4 or 8 child tiles). Red: A tile which refines to a single higher-resolution child occupying the same volume. see Viewport.debugBoundingBoxes Members Name Value Description None 0 Display no bounding boxes Volume 1 Display boxes representing the tile's full volume.
