trim curve meaning in English

剪切曲线
配平曲线

After analyzing general data structure of curved solid modeling , it proposes a boolean operation algorithm for motional curved solid modeling , the goal of algorithm is to ensure effectively robustly and accurately . the topology and geometry of solid is represented by trimmed curve surface and half - edge data structure . it applies the continuous ssi mentioned above to motional solid boolean operation , and uses the similarity of intersect curve to simplify ssi problem , it can save computation time
结合前面提到的连续变化曲面求交算法，在原有雕塑实体布尔操作的基础上，把连续变化曲面求交技术应用到运动雕塑实体布尔操作中，利用连续运动中曲面交线相似性进行求交简化，加快布尔操作计算时间，加入对连续运动实体的特殊处理，提升了运动雕塑实体布尔操作的计算效率。
