Spatial Mapping from scratch

JaggerJacknellJaggerJacknell ✭
in Questions And Answers

Hello everybody,

I'm pretty new to Hololens development and I'm completely lost with spatial mapping.
First of all what is the difference between spatial mapping, spatial understanding and spatial processing ? Do I need to have spatial mapping to do the others ?

I want to occlude my holograms after the mapping : how can I do ? They already have shaders so how can I apply occlusion grid shader to my holograms without losing the others ?

Thank you very much for your help.

    Mapping is what the lense does which produces your mesh. Processing is dealing with the data to clean it up, adjust it. Etc. Understanding is where you have shapes in the mesh defined as solid with possible collider. Usually defined as a flat surface with a shape , normal and Collider. The three steps go hand in hand with the understanding the hardest part since you have to take the input data and make some sense or of it so that it's usable. Granted unity provides almost 100% of this as part of the vr namespace.

    The path(page) has disappeared or lost in conversion with the new layout or reconfiguration of web pages. This was about spatial understanding.

    Watch these videos paying attention to every word. I hope this will work.
    1. This is for Spatial mapping. watch it. https://www.youtube.com/watch?v=zff2aQ1RaVo

    Spatial understanding: watch this video a few times paying attention. https://www.youtube.com/watch?v=iUmTi3_Ynus

    Spatial understanding module is a special wrapper above spatial mapping module. So start with the upper layer. Work with spatial understanding example. Read the scripts.

    After some time, once you know what understanding module does. u can go to spatial examples for little lower level access to mapping module. At that time read this page - https://developer.microsoft.com/en-us/windows/mixed-reality/spatial_mapping

    Ok, thanks. I think I get it. I want to add occlusion to my holograms now. How do I make it ? Do I need to add spatialMappingRenderer (I already have a spatial mapping prefab) ? I tried it but I only see hot pink instead of occlusion.

    Thanks.
