Hello everyone.

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 for neurosciences (FPS and holographic synchronization)

Hi,

I'm currently working on a neuroscience project to use the Hololens for neuroscience experimentations. I need to display holograms fully synchronized with the frame rate (i.e. : need to display holograms when the display is starting to refresh the new frame). I'm new with the hololens library, is it possible to display with this kind of synchronization ?

Also, we need to keep the highest FPS possible. Is it possible to keep a 60 global fps while recording/streaming ?

Is it possible also possible to display mono-chromatically at 240 fps ? Maybe only green at 120 fps ?

Thank you,

Jean-Philippe

  • To enable 60fps while recording/streaming you'll most likely want to use a second device and spectator view: https://developer.microsoft.com/en-us/windows/mixed-reality/spectator_view

    I have not personally tried to display at 240 or 120 but sometimes 60fps is hard enough to manage. It'd have to be extremely simple and even then I am not sure if the device renders that quickly. Hopefully someone else here can help you with that question.

    I do not think that mono-chromatically or just green would help. I think that plays a larger role in cameras that record video. This camera is reading spatial data. And the mixed reality objects are being rendered by shaders which don't care if the objects are one color or many colors. I could be wrong though.
