Question: What do u mean computer graphic for movies

Ian Stephenson answered on 19 Jun 2014:

On a modern movie pretty much every frame is modified by a computer.

On a fully animated movie (like Frozen, Shrek, Toy story) that starts with modelling, where someone creates a sculpture of the object on a computer. Then someone puts bones inside the model (this is called rigging), so that an animator can then move the bones, to move the character like a puppet. Once the animation is complete the scene is rendered, which is where the positions of all the objects are used to create an image.

While a lot of these tasks are done by artists, they’re supported by a massive team of TD’s (technical directors) who write the software they use. TD’s also handle the more technical parts of the animation, like “simulation” of cloth, water, explosions,hair and fur fires, and a whole much of other things. Computational Fluid Dynamics (CFD) for example is the maths and programming being how liquids move. It’s used to design cars and planes, by figuring out how the air will move over the surfaces, but its used in movies to make waves in oceans, or nice looking flames.

My personal area of work is in rendering, where we look at how light moves round the scene to create an image. We also have to consider how light interacts with surfaces. While we don’t have to be quite as precise as “real”scientists – after all it just has to look good, we use the same techniques.
