Volume editing with moving least squares is one of the effective schemes to achieve continuous and smooth deformation of existing volumes, but its interactive authoring has not been explored extensively. We present a framework for interactive editing of volume data with free-form deformation, which provides intuitive and interactive feedback on the fly. Given control points, we extend moving least squares with their visual metaphor to further encompass non-spatial attributes including lightness, density, and hues. Furthermore, a full GPU implementation of our framework achieves with instant real-time feedback with quick-and-easy volume editing metaphor.
