Description: 3D地形模拟2（带纹理）PocketPC版
依据一本OpenGL上的例子修改的，在OGLES上没有找到绘画QUAD的函数，就用了两个三角形来替代，主要用到的还有FOG等效果，其实在PPC上能够体现出来的性能极其有限了。
带纹理的，主要要用到glTexImage2D，效果如图。使用的时候将纹理文件tr.rgb放到根目录下即可。
运行时，按左右将重新生成随机地形，按下退出。

Description: The purpose of this demo is to create shadows using a technique called stencil
shadow volumes in a 3d scene. To do this we will not need the shadow matrix from
previous demo. In fact in order to perform this all we need is to render the
silhouette edges of an object (which are the outer edges of a object) extended in
a direction (which depends on the light position) into the stencil buffer twice. After
that we draw the scene twice, once for the dark parts of the scene (areas that are
shadowed) and once for the lit parts of the scene (areas that are not in a shadow).
With that you can create extremely realistic shadows in your scenes. At first glance
this sounds a lot more complicated than it really is. When it comes to the silhouette
edges we don t need to worry about that because the object casting a shadow in this
demo is a simple quad. So its outer edges are the same as every point that makes
it up.

Description: In the last tutorial I taught you how to display Triangles and Quads on the screen. In this tutorial I will teach you how to add 2 different types of coloring to the triangle and quad. Flat coloring will make the quad one solid color. Smooth coloring will blend the 3 colors specified at each point (vertex) of the triangle together, creating a nice blend of colors.
Using the code from the last tutorial, we will be adding to the DrawGLScene procedure. I will rewrite the entire procedure below, so if you plan to modify the last lesson, you can replace the DrawGLScene procedure with the code below, or just add code to the DrawGLScene procedure that is not already in the last tutorial. -In the last tutorial I taught you how to display Triangles and Quads on the screen.

MM54HC00/MM74HC00
Quad 2-Input NAND Gate
General Description
These NAND gates utilize advanced silicon-gate CMOS
technology to achieve operating speeds similar to LS-TTL
gates with the low power consumption of standard CMOS
integrated circuits. All gates have buffered outputs. All de-
vices have high noise immunity and the ability to drive 10
LS-TTL loads. The 54HC/74HC logic family is functionally
as well as pin-out compatible with the standard 54LS/74LS
logic family. All inputs are protected from damage due to
static discharge by internal diode clamps to VCC and
ground.
Features
Y Typical propagation delay: 8 ns
Y Wide power supply range: 2–6V
Y Low quiescent current: 20 mA maximum (74HC Series)
Y Low input current: 1 mA maximum
