Frozen is a computer-animated musical fantasy made in 2013. Frozen features realistic animation by giving inanimate objects life. The entire movie was created using animation software for example the main characters, settings. Within this film the animators also included 2D artwork within sequence of the film e.g Elsa’s magic and snow sculptures and also frozen fountains and floors.
The studio also created 7 new tools to help aid them in creation of the film, they used a software called Matthorn which helped them create the snow within the actual film, the animators wanted a tool that allowed them to create snow that gives off the same effect of real snow.
The producers and developers studied actual snow in order to capture the essence of snow, they wanted to create computer-generated snow that was just a real as the real thing, which was quite hard for the animators due to snow not being a liquid and not being a solid, the snow is a very big part within the film so they had to get it right, knowing this the effects team had to create a snowflake generator which then created 2,000 unique snowflake shapes. The team also struggled to get shots of heavy and deep snow that was believable .
Characters and faces are within the computer, it starts off with a simple face structure and the computer then adds similar overlays of muscle onto the face and once that has been carried out it then adds a layer of colour which would give off the effect of skin. Once the whole process is completed the muscle overlays are then programmed to replicate real muscles in order to give off the sense of realism.
To get all the body structures of the characters the animators would use a body tool which would then create bones and muscles which would be the main structure of most characters, using this tool allows Olaf and Elsa etc to flow more realistically, in order to gain this realism the animators would have to add interactive layers of fat, skin, muscles, hair and clothing.
Shaders normally handle shading, which can mean it can decide on the way different surfaces are affect to light. A shader can also make a rough surface to a smooth surface.
For some of the human characters, the animators frozen then used a complex shader that use such things called ‘flow controls’ which allows the animators to manipulate the direction and flow of the snow and grass, how it reacted to different conditions for example in snowy, windy day. Elsa’s hair contains 420,000 computer-generated strands; they used Tonic to carry out this task.
The productions also used spaces to help move around Olafs limbs and pieces, they would then use snow batcher to view the final look of the snow, they then would call upon Matthorn to assist in the capture highly detailed shots. They also used flourish to allow extra movement of twigs and leaves
