Intuitive volume eraser

We present the intuitive volume eraser, an interactive volume rendering tool, to aid direct volume data visualization and Transfer Function (TF) design. Our system adopts sketch-based editing interface which enables interactive exploring and editing operations in an intuitive and natural manner. The data features can be enlightened interactively as user desired. The editing results are saved faithfully with the What You See Is What You Get (WYSIWYG) scheme. We also provide a coupled transfer function editor for users who are used to the traditional TF editing interface. The result of experiments on various data demonstrates the effectiveness of the proposed intuitive volume eraser. The comparison of user experience also shows that our tool outperforms the state-of-the-art approaches in friendliness and efficacy.
