红宝书中有一节关于"缓冲区对象中的顶点数组"。
OpenGL VBOs specification. VBO is based on the vertex array(which has three steps:enable/define/draw array). 将array data放到server side, 并可以通过mapping得到buffer object的指针进而修改server side那边的data. 最后带有Usage Examples.

“VBOs are intended to enhance the capabilities of OpenGL by providing many of the benefits of immediate mode, display lists and vertex arrays, while avoiding some of the limitations. ”
