Summary

In this chapter, we learned about the basic concepts of rendering, rasterization, and shading, including light source models, the Lambertian shading model, and the Phong lighting model. We learned how to implement rendering, rasterization, and shading using PyTorch3D. We also learned how to change the parameters in the rendering process, such as ambient lighting, shininess, and specular colors, and how these parameters would affect the rendering results.

We then learned how to use the PyTorch optimizer. We went through a coding example, where the PyTorch optimizer was used on a PyTorch3D mini-batch. In the last part of the chapter, we learned how to use the PyTorch3D APIs for converting between the different representations or rotations and transformations.

In the next chapter, we will learn some more advanced techniques for using deformable mesh models for fitting real-world 3D data.
