Research methods and technical routes of the opening report (1) Research methods and steps The research of this project mainly uses methods such as action research, experimental research, and evaluation research. For large-scale experimental research on teaching design and teaching mode，will use action research methods. For individual innovative，small-scale teaching research，that can provide important insights，by establishing scientific hypotheses，using experimental research methods. The evaluation of the teaching model and the analysis of the teaching effect， use the evaluation research method. The research steps are as follows ： May XX-August XX ， data collection ， model building XX September XX-January XX ，Development software February XX-August XX ，teaching experiment ，evaluation revision XX September 2019-December XX ， Expansion Test ， Summary (2) Key Technologies 1.

Line and line segment intersection problem (example: POJ3304)
Judging whether a straight line intersects a line segment Judging whether a straight line intersects a line segment，This is not on Liu Rujia’s board，but you can get it after a little analysis，This is a simplified version of the intersection of line segments. // Obviously only need b1, b2 on both sides of a1, a2 ， no need to judge Whether a1 and a2 are on both sides of b1 and b2// where a1 and a2 are straight lines ， b1 and b2 are line segments bool SegLineInt(Point a1,Point a2,Point b1,Point b2) {double c1 = span> Cross(a2-a1,b1-a1), c2 = Cross( a2-a1,b2-a1);return dcmp(c1)*dcmp(c2)<&# 61;0;} Segments Time Limit: 1000MS Memory Limit: 65536K Total Submissions: 19074 Accepted: 6019 Description Given n segments in the two dimensional space, write a program, which determines if there exists a line such that after projecting these segments on it, all projected segments have at least one point in common. Input Input begins with a number T showing the number of test cases and then, T test cases follow. Each test case begins with a line containing a positive integer n ≤ 100 showing the number of segments. After that, n lines containing four real numbers x1 y1 x2…
