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.

Hello world

      Since this summer, I'm thinking that I could create a blog referencing the tools and the other things I created. This weekend, I thought that I must. If those tools have been useful for me, they can be useful for someone else. And, most of all, it makes no sense to try to improve something without sharing what you've done.

      I'm Simon Moreau, born in 1992. My first contact with visual effects was about 14 years old, with after effect, laser saber and making shitty movie with my brothers. You know what I mean !
      When I realized that I was able to spend hours on this more or less useless thing without getting tired, I understood that it could be my job.

      I did my studies in Montpellier, in ArtFX. I specialized myself in compositing. And made with a crazy team this amazing movie :

      Here is the link of the making of : https://vimeo.com/132258695

      Visual effect are magic tricks, as magicians we have to make the audience thinks that what they see is real. But in reality, we made it made it with cardboard and scotch-tape. Here is the fun ! :)

      I'm clearly more interested in the way of making something than in the result. It's like preferring building the model than playing with the Lego ! So I'have been digging in how all those things we use are working, in order to use them more wisely, and sometimes, to improve them.

      I learned scripting and every related things by myself, thanks to internet. Or should I say, thanks to the incredible amount of people sharing their knowledge. Thanks you humanity.

      I'm now working as Pipeline TD and Compositor artist in Automatik VFX in Berlin.
