3 Dimensions using opengl

[vermarajeev]

Hi aamer4yu,
Thanks for your reply

also saw the image u gave... well as far as i got it, u work in 2D and want to show them in 3D....

Yes you are in right path. I already have some 2D objects and want to show them in 3D.

well if u have fixes number of items, and know what items will be drawn, u can create a different view and add 3D objects to it

Is different view a QGlwidget???. If yes I tried it. But get only 2D view.
Now here is the main issue. How do I create a different view and add 3D objects to it. My sense says something like this

//GraphicsView

void graphicsView::paintEvent( QPaintEvent * event ){
    QPainter painter(this);
    paint( &painter );
}
 
void graphicsView::paint( QPainter* painter ){
     //Draw the object you want
}
 
void graphicsView::on3DViewerButtonClick(){
   m_glWid = new myGLWidget( this );  //here this is QGraphicsView
   m_glWid->show();
}

void graphicsView::paintEvent( QPaintEvent * event ){
    QPainter painter(this);
    paint( &painter );
}

void graphicsView::paint( QPainter* painter ){
     //Draw the object you want
}

void graphicsView::on3DViewerButtonClick(){
   m_glWid = new myGLWidget( this );  //here this is QGraphicsView
   m_glWid->show();
}

To copy to clipboard, switch view to plain text mode 

Now I got graphicsView object in QGLWidget. How do I proceed further. I know I need to override

paintGL() 
resizeGL()
initializeGL()

paintGL() 
resizeGL()
initializeGL()

To copy to clipboard, switch view to plain text mode 

I can even use paintEvent in GLWidget and the call paint member of GraphicsView like this

void GLWidget::paintEvent( QPaintEvent * event ){
    QPainter painter;
    painter.begin(this);
    m_graphicsView->paint(&painter);
    painter.end();
}

void GLWidget::paintEvent( QPaintEvent * event ){
    QPainter painter;
    painter.begin(this);
    m_graphicsView->paint(&painter);
    painter.end();
}

To copy to clipboard, switch view to plain text mode 

But now I get 2D on QGLWidget.
Did you mean something like this. Or Is there something else.

and yeah, is ur 3D view editable ??? i mean do u want items to be manipulated in 3D view, or just show a 3D view of the items ??

[/QUOTE]
Yes in some scenario. First I would be interested in representing a 2D object to 3D. If I succeed then move ahead for editing.

Hope I made some sense now. PLease let me know if still there is any confusion.

I'll go through the link you have given and see if I can get it.
Thanks
