Projects
To finish up this chapter, we’re going to make a couple of small
projects that use what we’ve learned about processing the depth data to
create actual fun applications. Each builds on the techniques you’ve
already learned: looping through the depth map to find the closest pixel, persisting data across multiple runs of
the draw function, and using that
data to provide an actual user interface.
For each of the applications, we’ll start with a basic version that just takes a small next step beyond the code we’ve already seen. Once we have that working, we’ll add a few refinements and advanced features and then conclude with a discussion of future possibilities that you can explore yourself.
First, we’re going to build an “invisible pencil” ...
