Point of view and rotation Two questions which cross over maths/3D imaging/computer science. I'm trying to describe a point of view of an item in a 3d space and subsequently its rotation in a paper I'm writing. Versions I've had read have confused readers.

The scene is as illustrated in the attached image - we are looking on as it were from the left-hand side of the scene.


How should I describe the view of the object from the eye symbol? I've termed it a "thirty degree elevated front view" - it's the 'front' that I think is most problematic.
Then if the object is rotated backwards along the x axis how do I describe that? I've said "transformation, specifically a rotation seventy degrees backwards along the x axis".


Are these the correct way of describing this point of view and rotation?
You could phrase it in terms of elevation away from various planes. So 30° above the x-z plane, and 0° from the y-z plane (or whatever it actually is). It's sort of like spherical coordinates where you'd have theta and phi.
