floor spatial mapping

I'm trying to map only the floor and remove all other vertices other than floor. similar to 3d viewer beta lock to floor scenario. but how do I search for the spatial mesh for the vector that has lowest Y value and an up vector? grateful if anyone could guide me.

@felsiska ,
Finding plane meshes that are floors is built into the HoloToolkit (which is considerably easier than trying to do it by hand since these spatial understanding scripts call a C++ dll).
You can find sample code in HoloToolkit\SpatialMapping\Tests\Support\SpatialProcessingTest
For a fuller example you should refer to the Spatial Understanding Feature Overview Example in HoloToolkit-Examples and specifically take a look at the LevelSolver class: HoloToolkit-Examples\SpatialUnderstanding\SpatialUnderstanding-FeatureOverview\Scripts\LevelSolver.cs

thx for the advice. roughly understood spatialProcessingTest but not LevelSolver. please correct me if I'm wrong. spatialProcessingTest uses SurfaceMeshesToPlanes to find the appropriate mesh positions and load a plane prefab through SurfacePlane. I can use SurfaceMeshesToPlanes to load planes only onto the floor. but the other vertices will cause objects to collide. or is there any way that I can disable spatial mapping after planes have been created?
@felsiska,
You've got it. Then to ensure that only floor planes are created, you can set the mask property of SurfaceMeshesToPlanes like this:
surfaceToPlanes.drawPlanesMask = = PlaneTypes.Floor;
this filters the plane types that can get instantiated.

@james_ashley
understood. is there a way to disable the spatial mapping when clicking on maybe a button? I do not want objects to collide with other vertices.
@james_ashley
also, the floor planes are 20-30cm higher than real floor surface. I've deleted the room meshes and recalibrated but still have this problem. any suggestion?
