摘要

This paper describes a greyscale "painting system" that enables the physical reproduction of digital texture maps on arbitrary 3D objects by selectively exposing "pixels" of photographic emulsion with a robot mounted light source. The system requires no bespoke production tooling and fills an automation gap in rapid prototyping and manufacturing technology that is currently occupied by hand painting. After reviewing existing methods of "decorating" 3D components, the properties of photographic emulsion are introduced and the nature of the rendering process' pixels discussed. A proposed path planning algorithm, used to derive both the robot's movement and the exposure times directly from a VRML representation, is then presented. Next, there is a description of the system's implementation and a discussion of the results obtained from rendering images on the surface of a test object. Finally, a discussion of the system's potential and limitations is given.
