Animation and level of detail are well explored fields but little has been done to generate level of detail automatically for dynamic articulated meshes. ...
Taking into account the aspect ratio of triangles helps to select operations that improve mesh quality. A flat triangle has a compactness near zero and should be decimated in priority (Figure 9 ). ...
