This paper reports on the linguistic analysis of a tag set of nearly 50,000 tags collected as part of the steve.museum project. The tags describe images of objects in museum collections. We present our results on morphological, part of speech and semantic analysis. We demonstrate that deeper tag processing provides valuable information for organizing and(More)
In 1994, Witkin and Heckbert developed a method for interactively modeling implicit surfaces by simultaneously constaining a particle system to lie on an implicit surface and vice-versa. This interface was demonstrated to be effective and easy to use on example models containing a few blobby spheres and cylinders. This system becomes much more difficult to(More)
We describe a C++ class hierarchy to support the efficient implementation of implicit surface functions and algorithms. The structure of the hierarchy allows many methods to be defined automatically over a wide range of specific implicit surface types. This structure also provides the infrasture for integrating many various methods and models found in(More)
