This chapter discusses intersection of line segments. A problem is presented in which for given two line segments in two dimensional (2D) space, it is to be determined whether they intersect or not. If they intersect, then the point of intersection is also determined. The chapter presents an...
intersection_segmentscalculates the intersection point of two line segments, which are defined by their endpoints (Segment1Row1,Segment1Column1), (Segment1Row2,Segment1Column2), and (Segment2Row1,Segment2Column1), (Segment2Row2,Segment2Column2) respectively. The intersection point, if it exists...
1.The intersection of line and plane was studied by using concept of double image line,thecrossing pointof line and plane was that of double imag.应用重影线的理念对直线与平面相交问题进行研究,得出直线与平面相交交点就是平面内与直线投影重影的那条直线与已知直线相交,即重影线的交点;直线的可见性就是...

Compute the intersection between 2 line segments NameTypeDescription x00numberThe x coordinate of the first line's first vertex. y00numberThe y coordinate of the first line's first vertex. x01numberThe x coordinate of the first line's second vertex. ...
This chapter presents an algorithm to determine whether two line segments in 2-D space intersect or not and to determine the point of intersection. Rapid calculation of line segment intersections is important because this function is often called a primitive many number of times in the inner loops...
The function segment_intersect( line1, line2 ) tries to deal with the fact that line1 and line2 define line segments, and there may be no point of intersection between them even when they aren't parallel (i.e., when the intersection point between the infinite lines isn't part of (at...
