Member Function Documentation

normalizeAzimuth()

static float com.google.appinventor.components.runtime.util.OrientationSensorUtil.normalizeAzimuth ( float  azimuth )

static

Normalizes azimuth to be in the range [0, 360).

Parameters

azimuth

an angle in degrees, likely to be in (-360, +360)

Returns

an equivalent angle in the range [0, 360)

Definition at line 47 of file OrientationSensorUtil.java.

normalizePitch()

static float com.google.appinventor.components.runtime.util.OrientationSensorUtil.normalizePitch ( float  pitch )

static

Normalizes pitch to be in the range [-180, +180).

Parameters

pitch

an angle in degrees, likely to be in (-360, +360)

Returns

an equivalent angle in the range [-180, +180)

Definition at line 57 of file OrientationSensorUtil.java.

normalizeRoll()

static float com.google.appinventor.components.runtime.util.OrientationSensorUtil.normalizeRoll ( float  roll )

static

Normalizes roll to be in the range [-90, +90] degrees. The App Inventor definition of Roll in the documentation is:

0 degrees when the device is level, increasing to 90 degrees as the device is tilted up onto its left side, and decreasing to -90 degrees when the device is tilted up onto its right side.

After rotating the phone more than 90 degrees, Roll decreased. For compatibility, we are guaranteeing the same behavior.

Parameters

roll	an angle likely to be in the range [-180, +180]

Returns

the equivalent angle in the range [-90, +90], where angles with an absolute value greater than 90 are reflected over the x-axis; the value is not defined for inputs outside of [-180, +180]
