Description
If the returned isValid
is XR_FALSE
, then it indicates that the
face tracker failed to track or lost track of the face, or the application
lost focus, or the consent for face tracking was denied.
If the returned isValid
is XR_TRUE
, the runtime must return all
weights (or all weights except eyes related weights, see
isEyeFollowingBlendshapesValid
).
If the returned isEyeFollowingBlendshapesValid
is XR_FALSE
, then
it indicates that the eye tracking driving blendshapes with prefix
XR_FACE_EXPRESSION_EYES_LOOK_*
lost track or the consent for eye tracking
was denied.
