快速成型中CLI模型的真实感图形研究

Research on true-color graphics of CLI models in rapid prototyping field

对CLI模型的真彩可视化问题进行了一定的研究。提出在OpenGL编程环境下 ,模型真彩可视化的关键在于三角形重划分。作者根据CLI模型的特征 ,将三角形重划分过程分为顶平面、底平面和侧面三个部分 ,并对顶平面和底平面应用Delaunay准则 ,对侧面应用最短距离算法。这种三角形重划分方法在快速成型软件应用中取得了卓有成效的效果。

Some research work has been carried out on the problem of the true-color visualization of CLI models,and an conclusion is summarized in this paper:under OpenGL environment,the key of models'true-color visualization is re-triangulation.The author refers to the characters of CLI models,divides the process of re-triangulation into threes parts;top plane,bottom plane and side surface.Moreover,Delaunay principle is implemented into top plane and bottom plane,while the shortest distance algorithm is implemented into side surface.As the result,distinguished effects are reached at rapid prototyping software's application.
