Public static functions

GetHeadForward

Vector3 GetHeadForward()

Gets the forward vector relative to the headset's rotation.

Details
Returns	The forward vector relative to the headset's rotation.

GetHeadPosition

Vector3 GetHeadPosition()

Gets the head's position.

Details
Returns	The head's position.

GetHeadRotation

Quaternion GetHeadRotation()

Gets the headset's rotation.

Details
Returns	The headset's rotation.

GetRayIntersection

float GetRayIntersection(
  GvrBasePointer.RaycastMode mode
)

Gets the distance at which the Direct and Camera raycasts intersect.

This is the point at which Hybrid mode will transition from Direct (closer than the intersection) to Camera (further than the intersection) mode.

Details
Parameters	mode The RaycastMode for which to get the intersection distance. Only returns non-zero when this is RaycastMode.Camera.
Returns	The distance at which the Direct and Camera raycasts intersect.

GetRecommendedMaxLaserDistance

float GetRecommendedMaxLaserDistance(
  GvrBasePointer.RaycastMode mode
)

Gets the recommended max laser distance, based on raycast mode.

Details
Parameters	mode The RaycastMode for which to get the recommended distance.
Returns	The recommended maximum laser distance for the given mode.

GetShrinkLaser

bool GetShrinkLaser(
  GvrBasePointer.RaycastMode mode
)

Returns a value indicating whether the laser is visually shrunken.

Details
Parameters	mode The RaycastMode for which to check behavior.
Returns	Returns true if the laser is shrunken, falsea otherwise.

GetViewportCenter

Vector2 GetViewportCenter()

Gets the center of the screen or eye texture, in pixels.

Details
Returns	The center of the screen, in pixels.
