The way you construct this test harness, and hence the way you approach OpenGL, is different in release 1.1 and 1.5. The 1.0 release approach is the same as release 1.1 as release 1.1 is a fix release for 1.0. As we realized there may be programmers out there using all three releases we will show you the test harness implementation using 1.0 and 1.1 in this chapter. And we will reimplement this OpenGL test harness again in chapter 13 using 1.5 SDK. Even if you are programming in SDK 1.5 you may want to read this section to understand how SDK 1.5 would have implemented the underlying abstraction. So this chapter is certainly a prerequisite for chapter 13.

This approach is similar to the approach taken by Android in SDK 1.5. In this approach we will cover how this can be done with in the confines of 1.0 and 1.1 releases. In Chapter 13 we will cover how SDK 1.5 gives almost all of this out of the box. Reimplementing this test harness using SDK 1.5 becomes very very simple. Even if you care only about 1.5 we strongly recommend that you atleast read this section to understand the motivation for the test harness.

If you are coding in SDK 1.5 do read chapter 12 and chapter 13. Chapter 12 covers the introduction to 1.5 and chapter 13 covers the simplified approach to OpenGL. However the first two sections of this chapter are still applicable and mandatory reading even under SDK 1.5
