Abstract: We present an interactive mesh deformation technique based on parametric curve manipulation. A set of lines sketched over the projection of the mesh model is used to create parametric curves, which can be interactively manipulated, thus deforming the associated surfaces. Such curves can be further combined to create skeletons in a simple way, providing some extra control over the deformation process. Additionally, parametric curves can be automatically extracted from suggestive contours, allowing the deformation to be performed directly on visually-important details of the model. A major advantage of our technique is that it requires no preprocessing, allowing users to immediately produce visually-pleasing mesh deformations while using an intuitive interface. This makes it a good choice for artistic prototyping, as well as for casual users. We demonstrate that, despite its conceptual simplicity, it is quite general, producing results that are visually similar to the ones obtained with more sophisticated and computationally-intensive mesh deformation and skinning techniques.
