Cylinder with gluCylinder()
-
Well, what i'm trying to do is to draw a Cylinder using GLUquadricObj and gluCylinder, i don't get any code errors, compiles fine. However i don't see the cylinder.
@void GLWindow::paintGL()
{
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1,0,0);
glBegin(GL_POLYGON);
GLUquadricObj *obj = gluNewQuadric();gluCylinder(obj, 1.0, 1, 3, 30, 30); glEnd();
}@
So, the question is, how do i make the Cylinder appear at the middle of the screen?

Fixed. I was doing: glMatrixMode(GL_MODELVIEW); and glMatrixMode(GL_PROJECTION); in resizeGL() which seems to have caused this.

Hmm,
something else to try as I continue to learn both OpenGL and Qt!

Ok Blastcore,
Heres a question
I added your lines to my simple window layout and did a build which kindly reminded me I had forgotten the include <GL/glu.h>
But I still have issues so suspected the glu libs needed adding too. I tried LIBS += glu but this didnt get me anywhere.
I am using Qt5.0.1 and have no issues with using basic GL_POLYGON but couldnt get the it to build. ( yep I have googled it!)
would appreciated any guidance you can offer.
