Abstract: Unlike generating reliefs from images and range data, this paper proposes an efficient method to generate both bas-reliefs and high-reliefs directly from three-dimensional (3D) meshes. To produce relief features that are visually appropriate, the 3D meshes must be scaled. In our proposed method, 3D unsharp masking is used to enhance the visual features in the 3D mesh. We compare average smoothing and Laplacian smoothing to achieve better smoothing results, and then employ a nonlinear

Using our method, relief models can be generated from arbitrary viewing positions with different gestures and combinations of multiple 3D models. The generated relief models demonstrate that our method is efficient and effective.
