convert to HMD coordinates

[Shio]

Hi, I am using Tobii pro VR integrated +TobiiXRSDK, and I want to convert the coordinates of the target on the unity 3D model to HMD coordinates. I would appreciate it if you could tell me how to do this.

If you are using this method to retrieve a gaze ray:
https://vr.tobii.com/sdk/develop/unity/documentation/api-reference/core/#tobiixrgeteyetrackingdatatobiixr_trackingspace

the parameter TobiiXR_TrackingSpace.Local would give you the gaze ray in HMD coordinate space.

Hi Mattias, thank you for your help. I’ll try it.
