How to design a thinning algorithm to find the center-line of a 2-dimensional long region, for instance a river in a geological map? or is there any other method to find the center-line of an irregula
OK I\'m definitely overlooking something painfully obvious but here\'s the problem: In my project I\'m using two types of collision: sphere to sphere and box to box.
I have three intersecting circles with inaccurate radii. How can I determine three out of six intersection points which form the intersection area? I w开发者_如何学JAVAas initially thinking of simply
I need to generate n random points in general position in the plane, i.e. no three points can lie on a same line. Points should have coordinates that are integers and lie inside a fixed square m x m
This should be a simple matter, but for some reason I can\'t grasp it. I have a parallelogram, defined as four points (in anti-clockwise order, but apart from that I do not know which corner is which
I would really like to know is there some tutorial or example on how to draw the blue circles that appear in the google maps app (the one that show you where u are). I would also like to know how when
In 3-D space I have an unordered set of, say, 6 points; something like开发者_运维百科 this: (A)*
is there a method for scale a set of points drawed in a m x n Canvas and then, redraw a equivalent set of points in 开发者_如何学JAVAa p x q canvas, where p < m and q < n? I know that the method
Maybe it is a silly questi开发者_开发百科on, but I couldn\'t find the answer in the handbook of ggplot2 nor with \"aunt\" google...
I have a UserControl that is 45x45 (hardcoded size - it\'s part of a grid of items). When a certain property has a value I want to show a \"clip\" in the upper right-hand corner indicating this. The v
