One challenge rising in 3DCG product visualization consists off accurately converting a CAD file to its mesh based polygon version. While CAD software do use common graphic library API for real-time display in their viewport, their export function often lacks of consistency and produce undesired noise.
Camera Mapping is a neat technique to fake 3D out of a photograph. It’s already been used in the game industry for awhile to give life to illustration and 2D game assets. The technique itself is fairly simple, but mastering it requires a special set of skills that are more about art and sense of motion than CG modelling.
All the 3D around the web is low-resolution, low-polygon, low-antialiasing based solution. In an other side off line CG rendering is all about high-resolution hight spec image processing. Between those two limits nothing exist. Well, not exactly,
