I try to draw a shpere by java, and refer to C. there is “GLUquadricObj *quadObj1;” in the C examlpe.I can
t find "GLUquadricObj" in the "eclipse.swt.opengl.GLU" which is a java for opengl jar. Even,I cant find it in OpenGL api doc,
but find it in glu.h with “typedef class GLUquadric GLUquadricObj;”. what is “GLUquadric”, how class will appear in the C language?
