Making stereographic 3D with the Node Editor

You've already used the Node Editor when you created depth of field in the previous chapter. Now, it's time to get a little bolder and use it to create stereographic 3D images, which will use the Node Editor's ability to modify an image.

Since red-cyan anaglyph glasses are an inexpensive way to get the 3D separation when viewing an image, you are going to turn the right and left eye images into a red image and a cyan image and then composite them.

Note

The stereographic images were created with the boat and oars that you made in Chapter 6, Making and Moving the Oars. They were recorded with a stereo rig adapted from the one you made in the bonus chapter, Chapter 6A, Using Stereographic Cameras and were then dropped into the world created in Chapter 10, Modeling Organic Forms, Sea, and Terrain.
