How can I get finishing spatial mapping?
Hey all,
I'm using Unity 5.6.3f1 and HoloToolkit. I'm having a problem about "SpatialMapping".
How can I get finishing spatial mapping? I don't have good way to notice finishing real world mapping....
When I start the app on HoloLens, it takes about five seconds that the mapping finished.
During scanning, my Unity 3Dmodel (with Rigid body) falls into the bottomless pit !!
Do you have a good way to notice of finishing SpatialMapping?
Any suggestions how to solve this?

If you are planning to use the Spatial Mesh as your "ground", you are probably better off using Spatial Understanding as it creates a very clean mesh for you. There is also a method you can call to finish the spatial understanding mesh. You could perhaps spawn your ball after you call the finish scanning method call. Or have the user press a button or say a command to instantiate the ball.

Hey, @sakata0211
To my knowledge spatial mapping process never really ends since HoloLens always tries to adjust it to the latest modifications of the physical world. It feeds the updated reconstructed spatial mesh into your SptialMappingCollider and SpatialMappingRenderer components at a desired rate. You can also freeze it processes, but you will freeze just that, feeding. The actual process is unstoppable and happens no matter what. The only thing you can do is go to Settings and delete the Space to re-initiate it. So there fundamentally is no "finishing real world mapping".
There is also no guarantee that a spatial mapping mesh is water-tight as far as I know. You can get the mesh if you only stared at the ceiling while the whole floor is absent. Your application should not assume water-tightness. If, however, it absolutely have to, you have to patch the spatial mapping mesh yourself. Alternatively you can introduce your own metric a'la "good enough" or "few enough small enough holes" to that your sphere won't fall through and wait until one arrives and even ask the user to keep looking around until the mesh satisfies the metric.
Hope this helps.

Thank you for your answers!!
I didn't know about "Spatial Understanding".
I'll try to study about it, and try to use it!
Thank you!
