3D Rendering

[Stu123]

Hi everyone just read that Wreck it Ralph wasn't made with a 3D camera but Rendered in 3D. Anyone care to explain what that means.

Since it wasn't live action it was never shot with any camera. Thus, created and rendered in 3D in a computer.

Yeah but i've been looking on wiki and they've described Despicable me as Digital 3D so what's the difference.

None

Anyone can wiki but few have background to be considered an authority on the topics they wiki on.

A little more detail on the topic:
Most 3D computer animated movies will render two cameras parallel next to each other. One camera can be considered the Lead camera (Right side), which will be the default for the 2D version, and the other camera could be considered the Left View Camera. In a computer generated world, you can squeeze the cameras as close together or as far apart as you need.

Parallel 3D cameras in computer animation are ideal to avoid certain disadvantages if a converged camera rig had been used, which is generally two cameras separate, but both pointing and angled in to a single target point, as is often done with live action in the real world, since parallel cameras might not be practical considering the massive distances the cameras might need to be separated.

To sum it up, for stronger 3D, separate the cameras further apart, but consider the foreground, mid and background objects and how they fit into the frame in a stereo 3D realm. Once that's all figured out, then render each camera "Eye", and then in a post editing 3D program, blend the two together so adjustments can be made, such as converging the dual images so the image pushes INTO the frame instead of sticking out of it.
