Over the next week, we’ll be taking a behind-the-scenes look of the incredible CGI in the film Alice in Wonderland (2010). In these videos, we learn about the enormous complexities of creating the mischievous Cheshire Cat.
During 2009-2010 SPI made transition from traditional biased, multi-pass rendering system to a largely singlepass, global illumination system incorporating modern ray-tracing and physically based shading techniques. They have achieved that with Arnold Renderer, an unbiased stochastic ray tracer, which is used in Alice.
Animator Ryan Page speaks in more detail about animating the cat’s expressions in the video below.
