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.
Put holograms over real world objects
I have 3D drawing of some big industrial equipment with pipes spanning several rooms and floors. I have imported these drawings into Unity and am able highlight single pipes.
Now I would like to overlay the real pipes on the industrial site with the holograms of the pipes, so that I can follow the pipe from room to room and floor to floor using the hololens.
I could of course align the hologram with the physical pipe by moving and rotating the hologram manually, but I believe it would not be very precise.
The alignment process I had in mind was to ask the user to gaze and tap at pre-defined reference points on the physical pipe at one end of the pipe and then use these reference points to overlay the holographic pipe over the physical pipe. I guess I will need three reference points to get correct alignment.
Is my alignment process doable? Can I anchor a pipe hologram to three anchor points (I have managed to use one)? Do I need to use one anchor and then calculate rotation vectors using the other two get the alignment correct? How can I calculate this?
