basic qt opengl problem

[kingslee]

Hallo people,
I have a array list of an object and I showing it in a screen and rotating.
When I rotate it it goes wavery. some files work normaly.

void GLWidget::paintGL()
{
    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );
 
    glPushMatrix();
 
    glTranslatef(0.0, 0.0, -10.0);
    glRotatef(xRot/16, 1.0, 0.0, 0.0);
    glRotatef(yRot/16, 0.0, 1.0, 0.0);
    glRotatef(zRot/16, 0.0, 0.0, 1.0);
    glCallList(1);             // call display list
    glPopMatrix();
 
 
}
 
 
void GLWidget::resizeGL(int width, int height)
{
 	GLfloat w = (float) width / (float) height;
	GLfloat h = 1.0;
 
	glViewport( 0, 0, width, height );
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
 
	glFrustum(-w, w, -h, h, 5.0, 60.0);
 
	//glOrtho(-1.5, +1.5, +1.5, -1.5, 4.0, 15.0);
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
	glTranslatef( 0.0, 0.0, -10.0 );
 
}

void GLWidget::paintGL()
{
    glClear( GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT );

    glPushMatrix();
  
    glTranslatef(0.0, 0.0, -10.0);
    glRotatef(xRot/16, 1.0, 0.0, 0.0);
    glRotatef(yRot/16, 0.0, 1.0, 0.0);
    glRotatef(zRot/16, 0.0, 0.0, 1.0);
    glCallList(1);             // call display list
    glPopMatrix();
 
  				 
}


void GLWidget::resizeGL(int width, int height)
{
 	GLfloat w = (float) width / (float) height;
	GLfloat h = 1.0;

	glViewport( 0, 0, width, height );
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
	
	glFrustum(-w, w, -h, h, 5.0, 60.0);
	
	//glOrtho(-1.5, +1.5, +1.5, -1.5, 4.0, 15.0);
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
	glTranslatef( 0.0, 0.0, -10.0 );

}

To copy to clipboard, switch view to plain text mode 

but for some objects its working fine.
i dont know whats wrong in this.

Is there anything wrong with my question or something unclear.

[jacek]

some files work normaly.

Then maybe the problem lies in those other files?

[kingslee]

Do you think the code can be used for any object array list?

I thaught the problem with the glrotate part , as its rotating in a circle.

[jacek]

Do you think the code can be used for any object array list?

What do you mean by "object array list"?

I don't see any problem why this code shouldn't work, provided that xRot, yRot and zRot variables have some normal values.
