This Example demonstrates various methods of working with polygon shapes and vertices.
This example covers the following functions:
* Different vertex types such as ofVertex, ofCurveVertex, ofBezierVertex
* Poly winding types using ofSetPolyMode
* Polygon building with ofBeginShape, ofEndShape, and ofNextContour
In the code, pay attention to:
* Different arguments for setting the poly winding type, such as ```ofSetPolyMode(OF_POLY_WINDING_NONZERO)``` and ```ofSetPolyMode(OF_POLY_WINDING_ODD)```.
* Methods for making closed and open polygons, using ```ofEndShape()``` and ```ofEndShape(OF_CLOSE)```
* Use of the struct ```draggableVertex``` in the ofApp.h
* Changing colors with ```ofSetHexColor()```
* Creating holes and constructive geometries with ```ofNextContour()```
* Toggling of shape fills, with ```ofFill()``` and ```ofNoFill();```.
* Rendering bitmap text to the screen, with ```ofDrawBitmapString()```.
### Expected Behavior
When launching this app, you should see a screen with
* 9 differently colored polygon shapes labeled (a) through (i)
