Abstract: Surface pasting is a composition method that applies features to base surfaces to provide details on the base surfaces. The location and size of a feature are determined by the transformations of the feature's domain. By modifying the domain layout of pasted surfaces, we can manipulate the appearance of a feature interactively in a Domain Space User Interface. However, this domain user interface is inconvenient because the user cannot interact with the three-dimensional model directly. In this paper, we describe a World Space User Interface that maps actions on the three space surfaces to two-dimensional domain operations.
