Hello everyone.

The Mixed Reality Forums here are no longer being used or maintained.

There are a few other places we would like to direct you to for support, both from Microsoft and from the community.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.

If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.

And always feel free to hit us up on Twitter @MxdRealityDev.

Microsoft Hololens: Spatial Mapping on Unity Project

Hello, i want to build an app for the microsoft hololens which represents virtual spiders moving in a real room to the hololens user. My app now can represent spiders which are moving to the camera and it works on the hololens but my problem now is to integrate the spatial mapping so the spider moves on the real floor not in the air. I have watched all Microsoft Holo Academy Videos and Holotoolkit but they only works with prescribed code so i don't find the answer yet.

Greetings Duc

    Hi, @hdd94

    Spiders moving over the room in Spatial Mapping terminology means gliding over the spatial mesh. There are many ways one could achieve this depending on how exactly your spiders need to move (in circles, doing a barrel roll, etc.).

    In any case you would have to define some kind of paths that lie within the spatial mesh. For that you need to analyse that spatial mesh and and perhaps define some sort of waypoints in it. Then simply connect those waypoints with any preferable curve type (bezier?). Then finally move the spiders along.

    If you don't want to analyse the spatial mesh you can always find the waypoints at runtime by gazing and confirming. Perhaps some kind of spider path editor mode of your app before you give it the actual user.

    Apologies for a broad answer, but it's a very broad question.
