解釋
表面顯示演算法-
In chapter 3, we discuss surface restoring method based on ct data which uses the intersection algorithm between spline curve and radial to resample the section curve, then works out surface controlling point array ; take opengl to display the surface with reality and the lighting, coloring effect
第三章討論了基於ct數據的曲面重構方法，利用樣條曲線與射線的求交演算法對截面曲線進行重新采樣，並反算曲面控制點陣；在其後的顯示過程中，利用opengl實現曲面的真實感顯示，包括顏色、光照的變化等。 -
Aiming at the existed problems in reverse engineering techniques concerning triangulation method for scattered data points, display technique of three dimension model based on mesh simplification, and redesign technique for re - constructed surface etc., this paper studies and proposes the relevant solving schemes, key algorithms and realizing technologies. the chief contributions acquired by this paper include : ( 1 ) an effective 3d triangulation algorithm for scattered data points is put forward. this algorithm solves the problem that data points must be partitioned for multi - projection realized by traditional 2d triangulation methods, and can also triangulate the scattered data points of trimmed surface and concave boundary surface
