Summary
In this chapter we explored some example programs that leverage the power of the Raspberry Pi 2's GPU.
Following this we delved into the framebuffer. Using the C programming language, we wrote a number of applications that used the framebuffer and memory to paint the screen a different color and to render lines upon it.
We ended with a brief discussion on polygons and methods for rendering both 2D and 3D shapes.
In the next chapter we will experiment with the Raspberry Pi's GPIO pins and learn how we can interact with other electronic components connected to our device.
