| 摘 要： | 提出了一种隐式曲面之间的求交方法,主要用于道路施工机械复杂曲面的求交计算.将其中的一个隐式曲面离散成许多三角面片,判断每个三角面片是否与另一个隐式曲面相交,求出交线,所有交线构成了隐式曲面之间的交线.此外还给出了一种交点的精确计算方法,使所得交线更加准确.

| Abstract: | The method for intersection between implicit surfaces which is used in highway equipment is presented. One of implicit surfaces is converted to many triangular patches. Another is determined whether to intersect with every patch. If intersected, find out intersections. All intersections form intersected curve between implicit surfaces. In addition, the method of finding precise point for intersection makes intersection more exact. |
