public class XrFaceExpressionStatusFB extends org.lwjgl.system.Struct<XrFaceExpressionStatusFB> implements org.lwjgl.system.NativeResource
Describes the status of facial expression weights.
Description

If the returned isValid is 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 TRUE, the runtime must return all weights (or all weights except eyes related weights, see isEyeFollowingBlendshapesValid).

If the returned isEyeFollowingBlendshapesValid is 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.

  • Constructor Details

    • XrFaceExpressionStatusFB

      public XrFaceExpressionStatusFB(ByteBuffer container)
      Creates a XrFaceExpressionStatusFB instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

  • Method Details

    • sizeof

      public int sizeof()
      Specified by:
      sizeof in class org.lwjgl.system.Struct<XrFaceExpressionStatusFB>

    • isValid

      public boolean isValid()
      an XrBool32 which indicates that the tracked expression weights are valid.

    • isEyeFollowingBlendshapesValid

      public boolean isEyeFollowingBlendshapesValid()
      an XrBool32 which indicates if the 8 expression weights with prefix XR_FACE_EXPRESSION_EYES_LOOK_* are valid.
