Summary

In this chapter, we first learned how to set up our development environment. We then talked about the most widely used 3D data representations. We then explored some concrete examples of 3D data representation by learning about the 3D data file formats, the PLY format and the OBJ format. Then, we learned about the basic concepts of 3D coordination systems and camera models. In the last part of the chapter, we learned how to build camera models and convert between different coordination systems through a hands-on coding example.

In the next chapter, we will talk about more important 3D deep learning concepts, such as rendering to convert 3D models to 2D images, heterogeneous mini-batching, and several ways to represent rotations.
