| Abstract: | In this paper, a dual-resolution modeling framework for a sketch-based animation editing system is presented. For the easy-to-use purpose, a sketch-based user interface is often used for editing a skeleton-based animation model. However, due to the loss of relationship information about the details of the model, a shape deformed from the skeleton in some cases will produce unexpected artifacts. To reduce these artifacts, in our system, we first generate a coarse mesh as an abstract layer from the input model based on quadratic error metrics while considering the skeleton constraints. Then, the original model is projected to the abstract layer to construct a displacement map to preserve the difference between the original model and the simplified one. Hence, when we apply a Laplacian-based smoothing operator to reduce the deforming artifacts, the smoothing operator can only be applied to the coarse mesh and provide the corresponding changes to the original model to obtain a smooth but feature preserved editing result. |
