Additional topics

In this chapter, we have considered some of the basic topics of 2D drawing. For reading further on openFrameworks 2D capabilities, we suggest the following topics:

• Drawing text using the function ofDrawBitmapString() or the class ofTrueTypeFont. See the openFrameworks example examples/graphics/fontShapesExample.

• Drawing filled shapes using the functions ofBeginShape(), ofVertex(), and ofEndShape() . See the openFrameworks example examples/graphics/polygonExample.

• Creating PDF files with openFrameworks drawings. Such files will contain vector graphics suitable for high-quality printing purposes. See the openFrameworks example examples/graphics/pdfExample.

For deeper exploration of the world of 2D graphics, we suggest the following topics:

• Using Perlin noise for simulating life-like motion of objects. See Appendix B, Perlin Noise.

• Using the algorithmic method of recursion for drawing branched structures like trees.
