Although animated meshes are frequently used in numerous domains
only few works have been proposed until now for simplifying such data. In this paper
we propose a new method for generating progressive animated models based on local feature analysis and deformation area preservation. We propose the use of solid angle and height value for a non-hyperbolic vertex to define the local feature parameter. This local factor is embedded to the vertex quadric error matrix when calculating the edge collapse cost. In order to preserve the areas with large deformation
we add deformation degree weight to the aggregated quadric errors when computing the unified edge contraction sequence. Finally
a mesh optimization process is proposed to further reduce the geometric distortion for each frame. Our approach is fast
easy to implement
and as a result good quality dynamic approximations with well-preserved fine details can be generated at any given frame. 2010 IEEE.

In computer graphics
animated models are widely used to represent time-varying data. In this paper
we propose an improved method to generate multiresolution animation models. We use a curvature sensitive quadric error metric (QEM) criterion as our basic measurement
which can preserve local features on the surface. We append a deformation weight to the aggregated edge contraction cost for the whole animation to preserve areas with large deformation. At last
we introduce a mesh optimization method to deal with the animation sequence
which can efficiently improve the temporal coherence and reduce visual artifacts. The results show our approach is efficient
easy to implement
and good quality progressive animation models can be generated at any level of detail. 2009 IEEE.
