On the Recent Work page, and indeed right here, is a video of a few of the shots I worked on for Orbit: Earth’s Extraordinary journey.
The first and last shots featured are both from the same ‘journey’ setup that was used for many other shots too. The setup featured many different elements on their own passes, each passed into its own part of a Nuke composition. As the project progressed, both the 3d scene and the Nuke script needed subtle reworking.
The second shot is a pair of emFluid particle systems, whereas the third is a simple enough ICE simulation in Softimage. The particles in those two shots were rendered with beta versions of Exorcortex’s Fury rendering system which loads the particles onto the graphics card, rendering them in OpenGL. Without Fury the second shot would have been particularly time-consuming to render. It contains millions of particles and took many many hours to cache out.
This Sunday at 2100 on BBC2 sees the start of Orbit: Earth’s Extraordinary Journey, a 3-parter presented by Kate Humble & Dr Helen Czerski about the Earth, its orbit, its tilt and how these things affect us all.
It’s something of a VFX-laden job with the task of creating graphicky goodness falling into the capable hands of Lola, London. This included myself as a freelancer.
I worked on a handful of complicated shots for this including one where the hot air above india rises, sucking in cold air off the sea. That was a very dense particle system with a few caching issues, but we got there eventually.
The hardest thing with this show is there are a lot of shots which explain slightly different things but which share a similar 3D scene. Creating an appropriate camera move around what are essentially spheres in space should be a simple deal. One shot I was tasked with shows the Sun rising over the Earth. We pull back to see the Earth as a whole passing through space then follow it round its orbit. That was one camera move. Sometimes it’s the apparently simplest things that are actually the hardest. Moving the camera in such a way as to get the Sun to rise at a constant speed, then following the Earth at a reasonably constant distance, but continually orbit the Sun as well, took a lot of fiddling. We had a camera rig which worked really well for close to the Earth shots but not for wide shots. In the end it was hand-animated without a rig.
The second tricky thing with space is scale. We regularly had to move the Sun much nearer the Earth than it really is so it can be seen clearly as opposed to being a tiny insignificant dot with less drama than a wet tea towel.
