maximumScreenSpaceError and maximumMemoryUsage

Hi, I have questions regarding these parameters for a tileset. What exactly do those do when you increase/reduce the values and how do they help with optimization? I managed to load a previously crashing tileset by playing with these values but I would like to know what those parameters actually change.

Hi @Rhea,

  • Maximum Screen Space Error— Increasing this value will request fewer high-resolution tiles, resulting in fewer network calls and less overall resources used.
    • Under the “Optimizations” section in this Sandcastle Example, try adjusting the maximum screenspace error and other parameters to see their effect on tiles loaded.
  • Maximum Memory Usage— Currently as it is implemented, it is a soft limit and does not guarantee that the limit will not ever be reached.
