Where anatomically is the HEAD joint
Not much detail here:
https://developers.meta.com/horizon/reference/spatial-sdk/v0.7.0/root/com.meta.spatial.toolkit/body-joint/h-e-a-d
Is it directly above where the spine meets the skull and behind the eyes? i.e. the "head atlas"? Is this a good pivot point for billboarding view screens?

Hi!
The recommended way to get users head position for placing screens is via the AvatarAttachment component.
You can get the local head pose like so:// Function to get the pose of the user's head fun getHeadPose(): Pose { val head = Query.where { has(AvatarAttachment.id) } .filter { isLocal() and by(AvatarAttachment.typeData).isEqualTo("head") } .eval() .first() return head.getComponent<Transform>().transform }Yes, I have that exact code. But where is the head on the human body exactly? Is it the C1 vertebrae? Center of skull? midpoint between eyes?
Hi,
It is the location of the headset in 3D Space.
For rendering purposes, it is also the midpoint between both eyes.
