isPointInPolygon
- 用射线法判断一个点是否在一个区域内,用c++写的,一个小程序,测试无误,大家可以交流下!-Ray method to judge whether a point is in a region with c++ write a small program, the test is correct, we can exchange the next!
D3CalCircleR
- 通过输入任意三点空间坐标自动判断三点是否在一条直线上,若不在则求三点外接圆的圆心位置和半径,计算精度可调节。解决了“知三点求圆心半径”程序对于某些点无法计算的缺陷。-Calculated the radium of circle on the base of three point space position.
isInAngle
- 判定某点是否在某一系列点围成的封闭多边形内-Determine a point surrounded in a series of closed polygons.

- 判断一个点是否在多边形内还是在多边形外-To determine whether a point is within a polygon
isinpolygo
- 判断点是否在多边形内,在VS2010能运行-To determine whether the point within the polygon, VS2010 can run
triangle-program
- 题目要求:首先由用户输入六个值,以作三角形的三个顶点坐标,构成一个三角形;然后由用户输入一个点坐标,由程序来判断该点是否在该三角形内,并输出结果,至此,程序运行结束! 算法思想: 1:判断用户输入是否为三角形是根据三角形三边关系(两边之和大于第三边,两边之差小于第三边)来判断。 2:判断点是否在三角形内:将所要判断的点的坐标和三角形一顶点坐标带入该顶点所对应的那条边所在的直线方程中,并将两结果相乘,循环判断三次(每
judge
- 判断一个点是否在两条线段(或是四个点)所包含的的区域内-Determine a point whether the two segments (or four points) are contained within the area

duobianxingnei
- 判断点是否在多边形内,算法经典,利用常用的射线法实现。-The code applys to judge whether the point is in the polygon.
find_in_tri
- 判定一个点是否在三角形里,这个函数我在各网站里都没有搜到,所以自己写了一个。函数运行耗费时间比较长,如果点太多的话,就不建议用这个函数了-Determine whether a point is inside the triangle, the function of the website where I have not found, so write one. Function takes a long time to run,
