There are a couple of recipes that use an orthographic camera and more advanced
tricks to compose the final rendering:
• In this chapter, we explored how to set up THREE.OrthographicCamera
in the Using an orthographic camera recipe.
• In Chapter 4 , Materials and Textures , we'll show how you can use an HTML5
canvas and a HTML5 video as an input to a texture in the Using HTML can-
vas as a texture and Using an HTML video as a texture recipes.
• In chapter 6 , Point Clouds and Postprocessing , we show you how to set up a
more complex rendering pipeline in the Setting up a postprocessing pipeline
recipe.
