Terrain editing on the fly

You can get the bounds of each and do your intersection that way.

I found a better way to achieve this. Since I have the level, x and y of the tile in the requestTileGeometry method, and also have access to the terrain provider tiling scheme, I used this._tilingScheme.tileXYToRectangle(x, y, level) to get the tile’s rectangle and checked if it overlaps the user’s polygon.

I’m not sure there’s an easy way to do this without making changes to the source.

Bummer… but I guess it won’t be so bad to have the terrain reloaded. We’ll see when I’m done

Sometimes the results do not look as good as the images above, probably because I’m using the same mesh with different heights instead of creating a new mesh. I need to find a performance efficient way of recreating it.

Right now I’m focused on this issue. I’m trying to break the mesh triangles that cross the polygon’s perimeter into smaller triangles so that the mesh will look good.

Will update soon with the results and post some of the code here
