I have two rays on a 2D plane that extend to infinity, but both开发者_开发技巧 have a starting point. They are both described by a starting point and a vector in the direction of the ray extending to
Given four points in the plane, A,B,X,Y, I wish to determine which of the following twoangles is smaller ∢ABX or ∢ABY.
Greetings, I am trying to bin an array of points (x, y) into an array of boxes [(x0, y0), (x1, y0), (x0, y1), (x1, y1)] (tuples are the corner points)
I\'m playing with XNA. When I click the left mouse button, I record the X,Y co-ordinates. Keeping the mouse button held down, moving the mouse draws a line from this origin to the current mouse positi
I\'m not a genius in geometry, I\'d like to find a point in as3 with the radius and a angle but I don\'t remember the rule, I know th开发者_JAVA技巧is should be simple!
I have n=10000 10-dimensional vectors. For every vector v1 I w开发者_JAVA百科ant to know the vector v2 that minimizes the angle between v1 and v2.
Problem Users can provide up to four latitude and longitude coordinates, in any order. They do so with Google Maps. Using Google\'s Polygon API (v3), the coordinates they select should highlight the
The problem of finding the intersection/union of \'N\' discs/circles on a flat plane was first proposed by M. I. Shamos in his 1978 thesis:
I\'m drawing a 3D pie chart that is calculated with in 3D vectors, projected to 2D vectors and then drawn on a Graphics object. I want to calculate the most left and right point of the circle after pr
By using left hand rule, I rotate one object left and right using y axis, and rotate up/down using x axis.
