Lesson 3 Adding Color

本文链接地址: Lesson 3 Adding Color

Expanding on the second tutorial I will teach you how to create spectacular colors in OpenGL with very little effort. You will learn about both flat coloring and smooth coloring. The triangle on the left uses smooth coloring. The square on the right is using flat coloring. Notice how the colors on the triangle blend together.  

Color adds alot to an OpenGL project. By understanding both flat and smooth coloring, you can greatly enhance the way your OpenGL demos look. 本作品采用知识共享署名 4.0 国际许可协议进行许可。

Using the source code from the first tutorial, we will now add code to create a Triangle, and a Square on the screen. I know you’re probably thinking to yourself “a triangle and square… oh joy”, but it really is a BIG deal. Just about everything you create in OpenGL will be created out of triangles and squares. If you don’t understand how to create a simple little triangle in Three Dimensional space, you’ll be completely lost down the road. So read through this chapter and learn. 本作品采用知识共享署名 4.0 国际许可协议进行许可。

Lesson 1 Setting Up An OpenGL Window

本文链接地址: Lesson 1 Setting Up An OpenGL Window

In this tutorial, I will teach you how to set up, and use OpenGL in a Windows environment. The program you create in this tutorial will display an empty OpenGL window, switch the computer into fullscreen or windowed mode, and wait for you to press ESC or close the Window to exit. It doesn’t sound like much, but this program will be the framework for every other tutorial I release in the next while. It’s very important to understand how OpenGL works, what goes into creating an OpenGL Window, and how to write simple easy to understand code. You can download the code at the end of the tutorial, but I definitely recommend you read over the tutorial at least once, before you start programming in OpenGL.本作品采用知识共享署名 4.0 国际许可协议进行许可。
