Modèle en 3D sketchup => 2D iso

Code :
=begin



The idea of this script is to get 8 view of a single objet, so as to snapshoot the image for a vidéo game in 2D isométric view.



In order to get my code functionnal :

1°/ first import one single modèle and select it.

2°/ then open ruby console. (menu > windows > ruby console)

3°/ write "middle" (to center the objet to the axis origin)

4°/ then write "aff" to get all view done with correct distance & angle

5-6-7..°/ then write i1, or i2, or i3 ... or i8 and snapshot the image, to get all 8 classical isometric direction for video game.



This was quickly done for Magdales.com game ... hope you'll enjoy. Please tell kéké at magdales@free.fr if you improve this script ^^.
