Direct Known Subclasses:

MotionOrientationEvent

public class OrientationEvent
extends PolarityEvent

Represents an event with an orientation that can take 4 values.

Orientation type output takes values 0-3; 0 is a horizontal edge (0 deg), 1 is an edge tilted up and to right (rotated CCW 45 deg), 2 is a vertical edge (rotated 90 deg), 3 is tilted up and to left (rotated 135 deg from horizontal edge).

Field Detail

orientation

public byte orientation

The orientation value.

hasOrientation

public boolean hasOrientation

Defaults to true; set to false to indicate unknown orientation.

unitVectors

public static final OrientationEvent.UnitVector[] unitVectors

An array of 4 nearest-neighbor unit vectors going CCW from horizontal.

these unitDirs are indexed by inputType, then by (inputType+4)%4 (opposite direction) when input type is orientation, then input type 0 is 0 deg horiz edge, so first index could be to down, second to up so list should start with down

Constructor Detail

OrientationEvent

public OrientationEvent()

Creates a new instance of OrientationEvent

Method Detail

getType

public int getType()

Orientation type output takes values 0-3; 0 is a horizontal edge (0 deg), 1 is an edge tilted up and to right (rotated CCW 45 deg), 2 is a vertical edge (rotated 90 deg), 3 is tilted up and to left (rotated 135 deg from horizontal edge).
