The metaio camera-COS is defined as follows: if the device is hold in
landscape mode with button to the right and the touch screen facing
you, then the positive X-axis points right, the positive Y-axis points
up and the positive Z-axis points to you | ________________________________ | | | | | | | ^ Y | | | | | | | |
| | | | | | -|--> X | O | | | \\ | | | | \\ | | | | v Z | | |
|________________________________| |
|________________________________________|This means: If device is hold: => then the gravity vector is:
landscape button right => 0 -1 0 landscape button left => 0 +1 0
portrait button down => +1 0 0 portrait button up => -1 0 0 lying
horizontal with screen facing up => 0 0 -1 lying horizontal with
screen facing down=> 0 0 +1Vector containing the last reading
The values can be used to set the OpenGL projection matrix according
to the camera parameters of the current camera.Currently you should use the left handed variant to work in
conjunction with getTrackingValues(float* matrix) as in the android
custom renderer example.
The methods returns the rendering performance as number of frames per
second.The mean rendering performance in frames per second over the last 25
frames.
The methods returns the image processing performance as number of
frames per second.The mean image processing performance in frames per second over the
last 25 frames.
It returns absolute translation of the geometry relative to current
LLA coordinates provided by the sensors' component.A 3D vector containing the translation in millimeters
See: setTranslation and getTranslation setTranslationLLA and getTranslationLLA
This transforms onTouch global screen coordinates into local view coordinate system,
while compensating for the visible window frame and local view dimensions.
