I want to draw lat/lon girds on Cesium surface, and have tried to use this example: https://groups.google.com/d/msg/cesium-dev/12agc5KrGQE/OLmI0zb70vkJ. But it seems to have some problems, like the grids don’t be drawn when latitude or longitude near 0, and it would be overlapped with terrain in 3D scene.
Cesium provides some related functions, GridImageryProvider and TileCoordinatesImageryProvider, to draw the grids and they look great. But I can’t change the intervals of lat/lon to 1°, 5°, or 10° since the amount of x,y grid value is always 2, 4, 8, 16… and other multiples of 2, and the intervals are 180°, 90°, 45°, 22.5° … Does it have any solution to make the intervals of lat/lon to 1°, 5°, or 10°? Or is it possible that using GridImageryProvider/TileCoordinatesImageryProvider to draw lat/lon grids?
Thanks a lot~
