I\'ve been experimenting with this and I haven\'t been able to come up with an adequate solution. Hoping one of you Mathletes can point me in the right direction.I\'m building a Snow Globe in ActionSc
I have some map files consisting of \'polylines\' (each line is just a list of vertices) representing tunnels, and I want to try and find the tunnel \'center line\' (shown, roughly, in red below).
I\'d like to be able to extract the geometry for each letter in a TrueType font file. Each letter would have a set of coordinates, assuming each letter is in its own grid.
I\'m trying to implement Jarvis\' algorithm for finding the convex 开发者_如何学Chull of a set of points, but for some reason it doesn\'t work. This is my implementation:
I need to calculate a chord`s starting and ending point, now I have the starting point which lies on the circumfrence of the circle and I also have the angle between starting point and ending point, b
If I get a line segment which was long enough to cross a given polygon, which could be concave or convex poly开发者_如何学Pythongon. How did I find the all the intersected light segments which was con
I\'m not sure what mathematical concept this is to support my question. ^^ Let\'s say we have PointA as the reference. The problem is to find the points around PointA within a g开发者_JAVA技巧iven ra
I have coordinates for 4 vectors defining a quad and another one for it\'s normal. I am trying to get the rotation of the quad. I get good results for rotation on X and Y just using the normal, but I
