Wheels & Wires

So on Thursday I had my last lecture for 3 weeks - short summer holiday here we come! Aside from a dissertation to start, house move to commence, various paying jobs that need to be started and lots and lots of reading to catch up on there is also that tiny compositing project I have going on..

So over the past week I've managed to squeeze in a few hours of compositing for Dark Side Of The Earth, so I'll give a quick update as to the progress of the shot I have been focusing on (which is still very far from being 100% finished, but I will get there soon!)

This particular shot is a little trickier than the last shot I covered as it is roughly twice as long (at 113 frames) and the characters manage a 360 degree turn around eachother as they fight. But, the bigger the challenge the more satisfying the solution, take a look:

The Original Shot

Obviously a few things need to change - namely the puppeteers need to vanish, the ceiling element and ropes must be added in and the whole thing has to match up and play smooothly (to simplify!)

The Current Shot

So this is where the shot is now - puppeteers have been successfully removed (apart from in the spokes of the swordsman's wheels - barely visible here but a real issue when he turns sideways) and the ceiling element has been added into the background. Next I need to clean up the masks that have brought back in character elements (such as The Swordsman's shield and arms) so that they move a little smoother, and correct the edges of the ceiling element so that it seamlessly connects to the background. In order to finish the shot I'll need to add in some convincing rope elements and light them accordingly to make them fit the shot. At least its on its way!

Finally, take a look at the script behind this 113 frame (around 4.7 seconds) shot:

Node Tree

Put simply each 'node' is a single action, mask or object - when interconnected they can work together to mask out characters, bring objects back in and add entirely new elements to the scene. Quite a lot going on but its a lot of fun when things are working properly.

Next time I'll update with a rundown of a completely different shot, in which we had to almost entirely rebuild The Swordsman himself!
