Visualization of height field data with physical models and texture photomapping

This paper discusses a unique way to visualize height field data - the use of solid fabricated parts with a photomapped texture to display scalar information. In this process, the data in a height field are turned into a 3D solid representation through solid freeform fabrication techniques, in our case Laminated Object Manufacturing. Next, that object is used as a 3D "photographic plate" to allow a texture image representing scalar data to be permanently mapped onto it. This paper discusses this process and how it can be used in different visualization situations.
