小球作圆周运动或者斜抛运动的模拟程序，openGL实现，运动时不出现闪烁现象，对初学者有很好的指引作用。-small ball circular motion ramps or parabolic movement simulation program, openGL realized, Movement does flicker, for beginners have a good role of the guidelines.

一段简单的OpenGL程序，主要功能是一个圆锥体在一个抛物线上运动-For a simple OpenGL program, the main function is a cone moving in a parabolic

利用opengl写的炮弹发射小界面，能连续发射子弹，抛物线轨迹等。-Use opengl write shells fired small interface, continuous firing bullets, parabolic trajectory.

展示一个小球的平抛轨迹，并增加小球撞击地面的形变。-It shows a small ball of flat parabolic trajectory, and to increase the ball hits the ground deformation.
