Please look at the picture (sorry, new users can\'t insert an image directly into post). Lines ar开发者_开发技巧e drawn semi-transparent colors (alpha = 0.5).
I have chosen a stack based traversal algorithm (Recursive Ray Traversal Algorithm), and I am having a little trouble understanding it.
We have a situation in which user will be drawing many lines on the screen and we 开发者_如何学编程need to find out the crossing lines and get intersection point.
What is, and is there, a fast way to check where in the plane my line will intersect, if i know the plane is always in the same z-axis (so it cannot be rotated), and its width/height is infinite? Also
I have been looking at posts about determining if a point lies within a polygon or not and the answers are either too vague, abstract, or complex for me.So I am going to try to ask my question specifi
i have a 3d world where i have several 2d circles laying on the开发者_运维百科 ground facing to the sky.
I h开发者_开发知识库ave two points in space, L1 and L2 that defines two points on a line. I have three points in space, P1, P2 and P3 that 3 points on a plane.
Lets say I have this data set... var a = [5,6,7]; var b = [9,8,6]; Imagine that those values were plotted the y in a (x,y) coordinate pair, and the x was开发者_StackOverflow中文版 the array index, h
How would I use numpy to calculate the intersection开发者_如何学JAVA between two line segments?
I\'m trying to write line intersection code to detect if two lines intersect. the form i have stuff in is there are O objects that can have Lo(l subscript O) lines, each line has 2 points and each poi
