Hi all,

Well I am trying to setup some radio buttons to allow some preset views of my model (e.g. top, right, left, etc.). I have managed to get all the views to work except one, the back/rear view. Here is what I have for the others:

1. // top view
2. scene.camera().setOrientation(0,0);
3. // front view
4. scene.camera().setOrientation(0,HALF_PI);
5. // left view
6. scene.camera().setOrientation(HALF_PI,-HALF_PI);
7. // right view
8. scene.camera().setOrientation(-HALF_PI,-HALF_PI);
9. // perspective view
10. scene.camera().setOrientation(new Quaternion(new PVector(-HALF_PI-QUARTER_PI, QUARTER_PI, -HALF_PI-QUARTER_PI),1));

I still don't quite get the orientation properties and that is why I am having problems with the back view. If I use:

1. scene.camera().setOrientation(0,-HALF_PI);

I'll get an upside-down back view!

Can someone explain to me how the orientations work?

Regards,
Ali
