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.  
Animated models coarsening with local area distortion and deformation degree control (EI CONFERENCE) 会议论文  OAI收割

In computer graphics applications  mesh coarsening is an important technique to alleviate the workload of visualization processing. Compared to the extensive works on static model approximation  very little attentions have been paid to animated models. In this paper  we propose a new method to approximate animated models with local area distortion and deformation degree control. Our method uses an improved quadric error metric guided by a local area distortion measurement as a basic hierarchy. Also  we define a deformation degree parameter to be embedded into the aggregated quadric errors  so areas with large deformation during the animation can be successfully preserved. 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 sharp features can be generated at any given frame. 2010 SPIE.

This paper introduces that using digital potentiometers output 24-channel resistance to simulate the thermistors. Every channel has two digital potentiometers  one is low resolution and high value  the other is high resolution and low value. They are connected through Daisy-Chain and share chip-select. 24-channel digital potentiometers share the SPI's clock and SDI. Input the parameter in the computer and then send it to the single-chip microcomputer. The single-chip microcomputer receives the parameter and sends it to the digital potentiometers. After correcting the errors  the system meets the demands which are resistance range of 040K and maximum error of 15. The design can replace the traditional way in which the mechanical potentiometers are used to simulate the thermistors. 2010 IEEE.
