Holograms 230 - Spatial Mapping - surfaceObserver not observing in Chapters 1 & 2

[roelkok]

If I follow Chapter 1: Scanning and Chapter 2: Visualization the project doesn't show anything in my HoloLens. The problem seems that StartObserver doesn't get called in the SpatialMappingManager. So no data is acquired and nothing will be displayed.

In Chapter 3: Processing there will be visual output once the PlaySpaceManager has been updated, because it will enter scanning mode if not enough surfaces have been found.

Agreed. I managed to make the example work again by porting code from the Toolkit version of SpatialMappingManager. This fixes the issue with no mesh being shown in Chapter 1 and Chapter 2.

Specifically I added the autoStartObserver property and Start method back into the SpatialMappingManager address this issue according to the implementation in the Toolkit.

       [Tooltip("Determines if the surface observer should be automatically started.")]
        public bool autoStartObserver = true;

        // Use for initialization.
        private void Start()
        {
            if (autoStartObserver)
            {
                StartObserver();
            }
        }

Hopefully this is an easy fix to actually apply.

Thanks for reporting this issue! I'm looking into it now and will be applying the fix shortly :)
