Rotate Current View 2D about Screen Z (Ruby solution)

[Gruff]

Okay I think I can attempt my first Ruby plugin with a little help.

I'm thinking that if I can get two points selected on screen and get the vector between them I can adjust my code below to rotate the SU view to a rotation about screen z.

Can someone give me a hand?

` model = Sketchup.active_model
view = model.active_view

Nab existing eye and target objects

eye = view.camera.eye
target = view.camera.target

Define a new camera object

newCamera = Sketchup::Camera.new

up = newCamera.up

Redfine Up vector, ignoring z (Last array element)

This should rotate the view about the screen center

Values should range from -1.0 tp 1.0 each I would imagine

up[0] = 1.0
up[1] = 1.0
up[2] = 0.0

Set new camera components

newCamera.set eye, target, up

Apply new view

status = view.camera=newCamera`
