We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.
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.
The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.
On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.
So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. 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. And always feel free to hit us up on Twitter @MxdRealityDev.
HoloLens spatial mapping objects shifting - Geolocation fix?
I am currently developing an application on the HoloLens, It’s an augmented reality application used for races. We recreated a real life circuit in Unity to be displayed while racing on a given track. This is all projected perfectly. However when we try and run around in our track, we get a message from the HoloLens stating that it is trying to map the location. When this message is resolved and the HoloLens has mapped the world outside again, the map and all objects placed in the Augmented reality world are shifted. Sometimes it takes a while until the message comes, at first we thought it was because of the speed as we were driving a small car at around 20 kmph, when we tested it on foot it also happened more often than not. Sometimes you could walk to the first turn without a problem, other times after 5 steps it would jump forward and all of the positioning’s would be off.
Is this a problem that can be solved by turning something off in the settings of the HoloLens or code something that counteracts the mapping position shift. Or is this just crossing the limits of what the HoloLens can handle. As it is an outside area that has to be mapped by the HoloLens it is not possible to map the entire place and import it into the HoloLens to be used.
All we use spatial mapping for at the moment is to place our objects and map and move around. If we were able to disable the unnecessary mapping functionalities it might fix the problem but we are unsure how to edit these settings if they are even edit able.
If this is a problem that cannot be fixed by the lacking performance of the HoloLens for this curtain task, we are looking into placing our objects upon GPS coordinates so that they are always on their correct spot, but at the moment we are unsure if they will also be shifted by the spatial mapping message as this freezes the entire application and then shifts everything forward.
If you have any ideas or remarks to help us further our research into this matter it would be greatly appreciated.
If we are looking at this the wrong way, please let us know as we are here to learn and to research the full potential of the HoloLens.
