How can I test intersesion ray and triangle, and if it exist how to get distance from ray origin to intersection point?开发者_运维问答?
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 have x1,y1 and x2,y2 which forms a line segment. How can I get another line x3,y3 - x4,y4 which is p开发者_StackOverflow社区arallel to the first line as in the picture. I can simply add n to x1 and
Suppose I have two points, Point1 and Point2. At any given time, these points may be at different positions-- they are not necessarily static.
I am looking for an algorithm as follows: Given a set of possibly overlapping rectangles (All of which are \"not rotated\", can be uniformly represented as (left,top,right,bottom) tuplets, etc...), i
I have a small contest problem in which is given a set of points, in 2D, that form a triangle. This triangle may be subject to an arbitrary rotation, may be subject to an arbitrary translation (both i

In industry, there is often a problem where you need to calculate the most efficient use of material, be it fabric, wood, metal etc. So the starting point is X amount of shapes of given dimensions, ma
I have images which have line segments, rays etc. I am representing these line segments using Bresenham algorithm (means whatever coordinates I get using this algorithm between two points).Now I want
I\'m trying to auto-detect the axis of rotation on a 3d pointcloud. In other words, if I took a small 3d pointcloud, chose a single axis of rotation, and make several copies of the points at differen
