Question: Flaten the world

[MateiGiurgiu]

Hi, I am wondering if there are any plans for adding flat world streaming. I have spatial data only as lat and lon without altitude, and is very hard to correctly place objects. I have seen your example from indoor building where you flatten the terrain and building by scaling them down, but I would like to keep the buildings as they are.

Thank you!

The Positioner class is intended to help with positioning objects at a lat-lng location, and optionally a height relative to the terrain at that location. See: https://wrld3d.com/unity/latest/docs/types/Wrld.Space.Positioners.Positioner/ And an example: https://wrld3d.com/unity/latest/docs/examples/fly-object-over-map/

For the forthcoming v0.7 release, we have made some improvements to Positioners, and added additional examples - we expect this to be available on Asset Store within the next few weeks.

Thank you. I need to convert a lot of LatLon point to their Unity World position, but I don't see any API in the Positioner class for getting the Unity World position, there is only a TryGetECEFLocation method.

Are there any plans for the future to include an API to directly convert a LatLon point to its Unity World space corespondent?

Hello there, The changes coming in the v0.7 release for the Positioner class will provide a way to do this. Until then, you should be able to use CameraApi.GeographicToWorldPoint(LatLongAltitude, Camera); see https://wrld3d.com/unity/latest/docs/types/Wrld.MapCamera.CameraApi/ .

Closing during sweep You can use a Positioner to place objects at a height relative to the terrain at a given lat-lon coordiate. https://wrld3d.com/unity/latest/docs/types/Wrld.Space.Positioners.PositionerApi/ See example here: https://wrld3d.com/unity/latest/docs/examples/position-object-with-positioner/
