The following examples focus on using built-in lighting models, and for examples of how to use custom lighting models, see surface Shader Lighting Examples.SimpleWe will start with a very simple shader, and gradually improve on this basis. The following shader will place the surface color "white". It uses the built-in Lam
I was asked what is the best way to learn a new library? My answer is to use it in the actual project. There are a variety of requirements in a real project that will encourage developers to explore and study the new library. In short, only the task itself will really motivate you to explore and learn. The new date and time API for Java 8 is the same. To learn about this new library of Java 8, here I have created 20 task-oriented examples. Let's start
