Description:
This 60-second spot opens with a germinating shoot breaking through the tarmac of a London street. Saplings and larger trees are then shown sprouting and growing in various locations around the city. Trees appear inside glass office buildings, lining the streets inOxford Circus, shooting from an underground platform, growing under the Centre Point tower, some complete with roots dangling beneath a nearby bridge. The Moving Picture Company also created CG forest in front of Battersea Power Station. The three main tree references were the Norwegian Spruce, the Scott’s Pine, and theSilver Birch.
MPC’s 3D department produced 25 shots over a six-to-eight-week period. The team created models of each of type of tree and then used BioNatics, software designed specifically to simulate the movement of growing trees. They also developed existing propri-etary technology to simulate the wind moving through the leaves and branches. This model reconstructs the dynamic effects of factors such as turbulence and wind on a body to give a natural look. Aspart of the process of compositing the CG trees into shots, digital matte painting techniques were used, for example, to add cracks in pavement around the trunks.
