What's the type of "m_meshCollection" in "Spatial mapping in DirectX"?
I am following the tutorial "Spatial mapping in DirectX (https://developer.microsoft.com/en-us/windows/holographic/spatial_mapping_in_directx)" but am stucking here:
Initialize and update the surface mesh collection
If the surface observer was successfully created, we can proceed to initialize our surface mesh collection. Here we use the pull model API to get the current set of observed surfaces right away:auto mapContainingSurfaceCollection = m_surfaceObserver->GetObservedSurfaces();
for (auto& pair : mapContainingSurfaceCollection)
{
// Store the ID and metadata for each surface.
auto const& id = pair->Key;
auto const& surfaceInfo = pair->Value;
m_meshCollection->AddOrUpdateSurface(id, surfaceInfo);
}
What's the definition of m_meshCollection and how it was initialized?

That is from the RealtimeSurfaceMeshRenderer class that they specify a little further down on that page. You have to create that class. Be warned that the m_meshCollection that is used inside of the RealtimeSurfaceMeshRenderer class is actually a map of the id and SurfaceMesh class. Which you also have to write. Read the whole page all the way through and the pieces should start to fall together.

That's really helpful. Thank you, Moktoe.
