I have an old plotter that can't handle printing true spirals. I need help with developing an algorithm to approximate a spiral. Here's a LISP sub-script that I have written which uses semicircles ...
I have a rasterized image that contains two colors: white and black. The black portion is entirely connected and looks like a big blob. Is there a good way to estimate the length of the boundary ...
I'm trying to implement the version of Appel's algorithm for vector hidden line removal (i.e. I'd like to avoid any form of rasterization). I found the description of this algorithm here - ...
Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the ...
So, the title is a little awkward. I'll give some background, and then ask my question. Background: I work as a web GIS application developer, but in my spare time I've been playing with map ...
Does anyone know a good algorithm for drawing an ellipse from a bounding box? draw_ellipse(int s1, int s2, int s3, int s4, color c); I don't need something optimized to incomprehendable , ...
Since there is an algorithm to blur images, so that part of it cannot be recognised, can we reverse the algorithm and unblur part of than image? Is there a program that already does that, is that ...
