Selection problems

I’ve got problems with object selection. I don’t now how can I choose objects made with glVertex i GL_SELECT render mode. Does anybody know the answer or know where can i find it?

Normally i apply GL_SELECT on the picking method…

#define BUFSIZE 1000
GLuint selectBuf[BUFSIZE];
glGetIntergerv(GL_VIEWPORT, viewport);
void glRenderMode(GL_SELECT);

try to find it in red book in page 541

Thanks for a tip but already solve that problem. But I’ve got another one. Is it possible to select object made with GLUquadricObj pointer??
