VS2012下基于Glut OpenGL显示一些立体图形示例程序(vs2019怎么用gets)

转自： Glut下提供了一些现成的绘制立体的API，如glutWireSphere绘制球，glutWireCone绘制椎体，glutWireCube绘制立体，glutWireTorus绘制甜圈，glutWireTeapot绘制茶壶，glutWireOctahedron绘制八面体。

推荐整理分享VS2012下基于Glut OpenGL显示一些立体图形示例程序(vs2019怎么用gets)，希望有所帮助，仅作参考，欢迎阅读内容。

Demo程序利用这些API绘制相应的立体，单击鼠标右键在弹出的菜单里可以选择需要绘制的立体以及是wire还是solid填充的，按键盘的UP、DOWN、LEFT、RIGHT按键可以旋转坐标系。由于Glut提供的多面体API默认半径是1.0f的，我使用glScalef对其进行了放大。示例效果如下：
