Capture: Allow the addition of an annotations without rendering to screen #1866

Closed gabrielDiaz-performlab closed 4 years ago

gabrielDiaz-performlab commented 4 years ago

The intention here is to facilitate writing out time-synchronized data programmatically from Unity. The issue is that large annotations including the positions, matrices, of several objects will tax the GPU and clutter the experimental screen. This seems a nice alternative to writing out my own data in my own format from Unity, only to have to later deal with issues related to synchrony.

Please, correct me if I am making oversimplifying assumptions about synchrony. I assume that every annotation would have an accompanying unity timestamp, and the conversion/synchronization with gaze data (and PLabs timestamps) would have to occur offline.

Or, perhaps PL team has already imagined a better path forward for the annotation of data captured in VR.

@performlabrit My apologies for this very delayed response. Yes, using annotations is a good way to store custom data within a Pupil Core recording. Based on our motivation for Pupil Core v2, we will not change any features in the near future. Instead, I would recommend using this custom plugin that does not log the incoming annotations.

Thanks very much, Pablo! I'll be sure to have a look once I get 2.1 working on my machine.
