Re: Star Wars Blu-Ray set could be in the works
The problem with computer graphics is this: they are perfect by default. In real life, you can't get objects anywhere near absolutely perfect (in shape and color, etc) especially not with the inherent graininess of real or digital film. With CG you always have to add imperfections for realism (like dirt on a clone trooper, or pock-marks in someone's face), and of course the CG is being rendered on the computer rather than captured through a lense and burned onto a piece of film (or saved to a cassette/memory card). Making real and CG blend perfectly is nearly impossible without heavy amounts of work towards details and imperfections. And no one wants to add slight graininess to their perfect high-def CG Yoda.
Also, lighting for 3D graphics is always simulated, and can never match perfectly with light in the real world. In theory, simulated light should work the same as real light based on mathematical formulas and calculations, but it still isn't real light. Usually simulated lights don't refract through the air as in real life, and it's quite possible that photons are pulled toward the earth by gravity and the computer doesn't replicate that. There are just so many possible variables that the computer probably isn't thinking about.
Things in CG are composed of tiny triangles that are stuck together, they have no substance and are entirely 2 dimensional (if you have a single 3D polygon and you look at it the edge, it will disappear. To make a true 3D model, you need multiple polygons). Polygons have no substance. They aren't composed of atoms or cells interacting with each other, so CG can never look entirely real until we can perfectly replicate something in a computer. That would mean, for example, making each and every individual atom inside each cell of a character's face in 3 dimensions, with bone cells underneath a layer of skin cells, with light refracting through the air and then through individual skin cells themselves. Each pore on the character's face would have to be replicated in 3 dimensions as well. Modern computers just don't have the processing power to do this efficiently.
CG can look pretty damn close to reality, but it will always be what it is: a simulation.
So of course the real puppet will look more real than a digital model, because it is actually there in real life interacting with light the same as the rest of the scene that it's in made out of substantial atoms being moved in real time by a real live person.
