Examples of java.awt.Graphics2D.rotate()

java.awt.Graphics2D.rotate()
Concatenates the current Graphics2D Transform with a rotation transform. Subsequent rendering is rotated by the specified radians relative to the previous origin. This is equivalent to calling transform(R), where R is an AffineTransform represented by the following matrix:
```
 [   cos(theta)    -sin(theta)    0   ] [   sin(theta)     cos(theta)    0   ] [       0              0         1   ] 
```
Rotating with a positive angle theta rotates points on the positive x axis toward the positive y axis. @param theta the angle of rotation in radians

                g2d.translate((fo1.getPosition().x*scaleFactor-viewCoordUL.x), (fo1.getPosition().y*scaleFactor-viewCoordUL.y));
                g2d.rotate(theta);
                g2d.scale(scaleFactor, scaleFactor);
                g2d.drawPolygon(ship);
