Greetings All!
This I bet should be an easy one for you all!
I'm using the MVPW routine to convert a point 3D perspective so I can display a
marker on to my Ortho2D heads up display camera:
Code:
osg::Matrix MVPW( camera->getViewMatrix()*
camera->getProjectectionMatrix() *
camera->getViewport()->computeWindowMatrix());
osg::Vec3 posIn2D = postIn3D * MVPW;
Works Great as long as i don't resize the screen. When I do that the object
develops a delta that moves to the right when you stretch the view width and up
when you stretch the height down.
In case you’re wondering the resize routine looks like this:
Code:
osg::ref_ptr< osgViwer::GraphicsWindowEnbedded > _gw; // just so you know what
_gw is.
// this is the resize function. It works inside a child class of QGLWidget in
yep, good old QT!
void osgGenWidget::resizeGL( int width, int height )
{
_gw->getEventQueue()->windowResize(0,0,width, height);
_gw->resized(0,0,width,height);
resize(width,height);
}
Sorry for any code errors, I had to hand-jam this code segment in!
...
Thanks!
