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.
Origin of spatial mapping mesh from Device Portal
I made simple app to take a picture from webcam in hololens and extracting camera-to-world matrix to get origin (0,0,0) of webcam in world coordinates.
Last column in camera-to-world matrix by calling TryGetCameraToWorldMatrix() function supposes to be webcam's origin in world coordinates, right?
Then, I am trying to get the spatial mapping mesh from Device portal by simply clicking 'save' button in 3D view menu but it seems like mesh saved from device portal has different origin points (rotated and translated) each time based on clicking 'update' button or moving.
I thought world coordinate's origin point is staying at fixed location. I guess it is not. Should I save spatial mapping mesh from my app as well to save both spatial mapping mesh and picture with same world coordinate origin?
