webGLContext.UNSIGNED_SHORT, 0);

mvPopMatrix();

Finally, we increase the rotateCube variable so that the next time drawScreen() is called, the cube will be updated with a new angle. The code below adds 2 degrees to the rotation angle each time drawScreen() is called:

rotateCube += 2;

}

Example 11-1 gives the full code listing for CH11EX1.html. Notice that many of the code styles and constructs we have used over the past 10 chapters are still in place in this application. Besides the obvious inclusion of code related directly to WebGL, this application operates essentially the same way as the other apps we discussed in this book.
