Very good TIG!!! Could it project on other objects too or only on ground floor?

[RPNZ]

Hey TIG, this is all great information,
is there a way of projecting on the ground and onto a vertical surface ? ie onto a street and onto a building across the street? So the "object is projected on the flat and vertical surfaces in the same drawing?
thanks..

Do you know these painters, drawing a painting on the floor in a pedestrian area? Some of these paintings use a fantastic trick, so that if you stand at one specific point you will see a hole in the ground or similar. They do it via perspective distortion.

Julian Beever is probably the most famous. http://www.julianbeever.net/index.php?option=com_content&view=article&id=1&Itemid=1

Here is a basic tutorial http://www.instructables.com/id/3D-Anamorphic-Street-Art/

Heres mine: Nancy with a basketball, in scene 1 the ball looks normal. In scene 2 you can clearly see how the ball is flat and distorted by using the scale tool and how long the anamorphic images have to be to get the desired effect.

eye = [1000,1000,1000]
target = [0,0,0]
up = [0,0,1]
my_camera = Sketchup;;Camera.new(eye, target, up)
Sketchup.active_model.active_view.camera = my_camera

Vary the eye and target as desired...

@RPNZ:
Try my Projections extension, I think it can do it

It works! Thank you.
The shadows can be easily redrawn by hand.
