Hi, try to use like this

 

glMatrixMode(GL_MODELVIEW);

glPushMatrix();

glTranslatef(x,y,z);//x,y,z is your position

/*

Other Stuff

*/

gluDisk

 

glPopMatrix();

 

If you have massieve disk, I suggest you have a look at the glu source code, manually implement it, load the all vertex into a vertex buffer object, then draw, it will be much more efficient than OpenGL immediatly mode.

Subject: [cgal-discuss] help using gluDisk

Houston - got a trouble here...

Consider the small thread:
---------------------------------------

glColor3ub(0, 0, 0);

GLUquadricObj* quadricPtr;

quadricPtr = gluNewQuadric();

gluQuadricDrawStyle(quadricPtr, GLU_LINE);

gluQuadricNormals(quadricPtr, GLU_SMOOTH);

gluDisk(quadricPtr,10.0f,15.0f,5,1);

glFlush();

glutSwapBuffers();
---------------------------------------------

It works fine, draws a disk which the point coordinates of the center are (0,0), and that's okay.
Suppose now I need to draw a disk at any position (x,y), how do I implement it?

can you help me on this issue?

Best Cordial Regards,
m.s.l.f
