在这一节中主要简单介绍下怎样给平面几何着色,以及怎样让绘制出来的几何图形旋转起来。在上一节OpenGL_Qt学习笔记之_02(绘制简单平面几何图形) 中已经介绍了如何利用opengl画一些简单的图像，那么这一节就在上面的基础上给它着色，且让他旋转。-The main brief in this section under how to plane geometry shader, and how to draw out geometry rotation. A OpenGL_Qt study notes _02 (draw a simple plane geometry) describes how to use opengl draw some simple image, then this section to it on the basis of the above, coloring, and let his rotation.
