The Direct Manipulation of Pasted Surfaces

Abstract

Surface pasting is a method for creating complex composite surfaces by adding local detail or feature surfaces to a base surface. Previous surface pasting editors enabled users to paste, translate, rotate, and resize feature surfaces, but none allowed users to directly manipulate a surface in the pasting hierarchy. In this thesis, I propose a multiresolution direct manipulation technique that allows the user to pick a point on a surface and move it to a new location and have the shape of the surface change appropriately. My method provides a more flexible modelling paradigm for pasted surfaces by allowing the user to pick both the new location of the selected point and the granularity of the change that is applied to the composite surface.
