Abstract
Official abstract text for this publication.
Methods and apparatus for interactive curve-based freeform deformation of three-dimensional (3-D) models may provide a user interface that allows a user to interactively deform 3-D models based on simple and intuitive manipulations of a curve drawn on the model (i.e., freeform deformation). The user may apply freeform deformations using touch and/or multitouch gestures to specify and manipulate a deformation curve. The deformations may be applied by deforming the space around a curve/sweep path and deforming the 3-D model accordingly. The freeform deformation methods are not dependent on manipulation of a fixed set of parameters to perform deformations, and may provide for both local and global deformation. One or more weights and user interface elements for controlling those weights may be provided that allow the user to control the extent (region of influence) of the freeform deformations along the curve and/or perpendicular to the curve.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: applying, by one or more computing devices, a deformation to a three-dimensional (3-D) model that is represented as a mesh comprising a plurality of mesh points, said applying the deformation to the 3-D model comprising: generating a curve as a polyline having an orthogonal frame attached at each of a plurality of points of the polyline, one or more of the mesh points of the 3-D model bound to each of the orthogonal frames, the one or…
