API Reference > imodeljs-frontend > Views > Viewport > numReadyTiles numReadyTiles AccessorReadOnly The number of tiles which were ready and met the desired level-of-detail for display in the view as of the most recently-drawn frame. These tiles may not have been selected because some other (probably sibling) tiles were not ready for display. This is a useful metric for determining how "complete" the view is - e.g., one indicator of progress toward view completion can be expressed as: (numReadyTiles) / (numReadyTiles + numRequestedTiles) numReadyTiles: number see Viewport.numSelectedTiles see Viewport.numRequestedTiles Returns - number Defined in core/frontend/src/Viewport.ts Line 1533 Last Updated: 11 June, 2024
