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.
WorldAnchor in Spatial Mapping
Hi all, I'm new to HoloLens application developing, and I have a few questions regarding the WorldAnchor used in spatial mapping.
I'm interested in developing an app which maps texture onto the spatial mapping mesh using the HoloLens' camera. But to achieve this, I will first need to know the position/co-ordinate of each of the spatial mesh (I believe they're called meshFilter?) As far as I know, these meshFilter all have a unique WorldAnchor associated with them.
My question is, is there a way to identify these anchors using position/co-ordinate? Or even finding the closest anchor given a co-ordinate would be helpful. Currently I think the anchors are identified by an ID, and has no information about this anchor's position relative to the physical world.
But if there is no co-ordinate information of the physical world associated with each anchor, how does HoloLens anchor holograms internally?
