Syntax
public struct XrSingleEyePupilDataHTCConstructors
XrSingleEyePupilDataHTC(XrBool32, XrBool32, float, XrVector2f)
Declaration
public XrSingleEyePupilDataHTC(XrBool32 in_isDiameterValid, XrBool32 in_isPositionValid, float in_pupilDiameter, XrVector2f in_pupilPosition)Parameters
| Type | Name | Description |
|---|---|---|
| XrBool32 | in_isDiameterValid | An XrBool32 indicating if the returned gazePose is valid. Callers should check the validity of pose prior to use. |
| XrBool32 | in_isPositionValid | An XrBool32 indicating if the returned pupilPosition is valid. Callers should check the validity of position prior to use. |
| float | in_pupilDiameter | The diameter of pupil in millimeters. |
| XrVector2f | in_pupilPosition | The position of pupil in sensor area which x and y are normalized in [0,1]with +Y up and +X to the right. |
Fields
isDiameterValid
An XrBool32 indicating if the returned pupilDiameter is valid. Callers should check the validity of diameter prior to use.
