Thanks Nick, I implement it but some modifications caused another problem I don't understand.
In the old code I created a cross axes with size=1.5 for each axis. The ortho camera was defined as follows: camera->setProjectionMatrix(osg::Matrix::ortho2D(-1.7, 17.75, -1.7, 13.86)); Then I had to fix the resize problem as you suggested. So, on resize event I used the actual viewer width and height. Here is basically the call: camera->setProjectionMatrix(osg::Matrix::ortho2D(-axisSize, iWidth-axisSize, -axisSize, iHeight-axisSize)); but the axis size=1.5 was to small in this case and I had to increase it to 70 to be seen. Now the problem. On top of each axis an osgText to diplays the labels X, Y and Z. When an axis points towards out of the screen (more or less) the label disappears. In the previous implementation with axis size=1.5 it worked correctly. Can you please explain me why?
