In computation of swept volume approximation, an improved technique to generate the swept volume approximation for arbitrary meshes is presented by introducing generator simplification and path resample using frenet moving frames along the discreted sweeping trajectory. other steps, such as a directed distance field computation on a uniform grid based on the hardware accelerated computation technique and iso - surface extraction using marching cubes algorithm, are also included in this algorithm. in addition, the simplification scheme and smoothing technique are applied to the swept volume generated from iso - surface extraction
本文的主要貢獻在於：在掃描體逼近計算方面，在原有任意多邊形網格模型沿任意路徑運動生成掃描體逼近演算法的基礎上，提出了加入對掃描母體簡化的預處理和用活動標架對掃描路徑進行重采樣等過程，演算法的其它過程還包括：計算掃描體中幾何基元的排列，用硬體加速構造無符號的有向距離場，將無符號距離場轉化為有符號距離場，從有符號有向距離場提取等值面等。 -
The improvements in the iaga contained adding strengthen operator, improving evaluation index of premature, etc. multi - phase homing project, making use of the flight properties of parafoil system in gliding and turning, was simple in control and facile in practice. based on frenet frame, the linear time - variable error equations of parafoil system were built
基於frenet坐標系推導和建立了翼傘系統線性時不變的誤差方程，並運用「投影點」的思想來獲得frenet坐標系下偏差量的解析近似表達式，從而設計了用於翼傘系統航跡跟蹤的傳統pd控制器和增益調節型模糊pd控制器。 -
We first set up the hiberarchy of the nmm ’ s visualization and focus on the study of pem ’ s visual process. then the coupling equation of pem is deduced and a rapid algorithm for solutions of bordered tridiagonal linear equations is put forward. in the last of the thesis, elementary system of deformation geometry unified for manifold ’ s structure is studied primarily via the idea of unified modeling and some theoretic results for analytical visualization are given out under the system of frenet frame of arbitrary parameters
