Final Project

The effect I was going for is that I have Hiro Protagonist ,from the novel Snowcrash, entering the storage shed to practice with his samurai sword online. He has goggles that he puts on and this enters him into his online space in the dojo. So he enters the storage, puts on the goggles and his background changes as the dojo is loading into his goggles; next his new appearance begins loading and finishes, leaving him with a sword and ninja outfit; finally the dojo finishes loading up and fully appears. After this he begins practicing.

To achieve this effect I created two different masked images and masked them together with a separate mask. First I masked out the backgrounds to put the subject in the two different places. Next I took the moment the backgrounds were transitioning and created a mask for the foreground, so only the subject would be masked but the background would not.

The effect still needs some polishing and I believe the fault is that lighting for this effect should be more consistent for the right amount of color to be removed. I faced certain time constraints for my filming schedule but I will continue to work on this effect as I feel it has the possibility to turn out quite cool.

Here's the Code I used for the Final Project:
