Chapter 6. Fragment Shaders and Grab Passes

So far, we have relied on Surface Shaders. They have been designed to simplify the way shader coding works, providing meaningful tools for artists. If we want to push our knowledge of shaders further, we need to venture into the territory of Vertex and Fragment Shaders.

In this chapter, you will learn the following recipes:

• Understanding Vertex and Fragment Shaders
• Using grab pass
• Implementing a Glass Shader
• Implementing a Water Shader for 2D games
