Java 2D Graphics Angle

Description

Click the following links for the tutorial for 2D Graphics and Angle.

1. Calculates twice the area of a triangle for points specified in counter-clockwise order (if the points are specified in clockwise order the result will be negative).
2. Returns absolute angle form point to target
3. Returns the angle between the two vectors.
4. angle Between Oriented
5. simplify Angle
6. subtract 180 Angle
7. Returns the input angle put into the 360 degree range centered on the input center, [center-180, center+180)
8. Returns the input angle put into the 2pi radian range centered on the input center, [center-pi, center+pi)



9. Given an input angle in radians, return an equivalent angle constrained to lie in the range (-pi, pi].
10. angle for a point
11. opposite Angle
12. Return the angle to turn of to go from an angle to the other
13. Normalize an angle so that it belongs to the [0, 360[ range.
14. is Ordinal angle
15. Returns true whenever the angle is between min Angle and max Angle, false otherwise.
16. Increments current Angle by angle, truncating at desired Angle.



17. Returns the difference between two angles in degrees between -180 and 180
18. Normalizes an angle value between a given range
19. point To Angle
