Unlimited Camera Transition

http://www.nukepedia.com/gizmos/3d/fusioncam

This is actually the first interesting script I've done in nuke.
I wanted to improve the common expression used to make a camera transition :

1-sliderValue*Camera1.translate + sliderValue*Camera2.translate

In order to use it with an unlimited amount of camera, I modified a switch node : easy way to have an unlimited number of input branches.

Then the expression goes like this (gizmo is the created switch node) :

(1 - sliderValue - int(sliderValue)) * gizmo.input(int(sliderValue)).translate +
(sliderValue - int(sliderValue)) * gizmo.input(int(sliderValue) + 1).translate

Substracting the sliderValue converted in int conforms the sliderValue between 0 and 1, then the expression works the same but instead of Camera1 and Camera2, we have Camera(int(sliderValue)) et Camera(int(sliderValue) + 1) 

This expression doesn't work when sliderValue = int(sliderValue) so I had to add an exception :
if sliderValue == int(sliderValue) : gizmo.input(int(sliderValue)).translate

I'm not using the real nuke tcl syntax in order to explain it. You can find the full expression in the gizmo.

If you have any trouble installing, using or understanding this tool, please ask. I'll be very happy to help !
