Represents a loading approach for 3D Data such as 3D tiles. This strategy can have a large impact on memory usage, latency and visual behavior of your dataset. This strategy can be set using TileSet3DLayer.loadingStrategy

DETAIL_FIRST: 0

This loading strategy will prioritize downloading detailed 3D data, given the current camera position. This results in low latency as well as low memory usage. The downside is that when the camera moves quickly, holes can appear temporarily where no data has been requested before.

For tiles with "additive" refinement, tiles of different levels will be loaded concurrently.

This is the best strategy for tiles with "additive" refinement. This includes HSPC.

OVERVIEW_FIRST: 1

This loading strategy will prioritize downloading low-level overview 3D data, given the current camera position. This strategy will download tile levels in-order until the required detail level is achieved. This has the benefit that it behaves better when the camera is moving around quickly. The downside is that it has a relatively high latency and an increased memory requirement to store the additional tile levels.

This is the best strategy for tiles with "replacement" refinement. This is usually the case for OGC 3D Tiles.
