The most recent Dreamworks film to be released; ‘Up’, is abundant in its believability and realism with every movement mimicking life flawlessly. Not only is it honed down to every last detail it is also a stunning thing to witness. Watching the behind the scenes of most Dreamworks films you see that before they start to animate they film every sequence in real life with real people in order to trace the movement with CGI. For a section of the opening sequence where the main character's wife fixes a series of different neck ties, everything right down to the material is lifelike. They study the movement of fabric, the manipulation of the material's pattern as the movement is carried out, every cloth dip and shadow all so they can apply this to the animation.



I have been explained to about how, in animation, even the simplist movement needs to be carefully considered extensively in order to seem realistic. A prime example of this fact is the bouncing of a ball. An animator would have to consider the energy gained and lost with every ball's bounce, every little contraction and expansion of the ball itself as it hits and leaves the ground, the ball's material and how it would react to the movement...all thing
