## Radial plotting algorithm

I have to write an algorithm in AS3.0 that plots the location of points radially. I'd like to input a radius and an angle at which the point should be placed. Obviously I remember from geometry coursework that ...Learn MoreGraphMathGeometryGraphics## Count number of points inside a circle fast

Given a set of n points on plane, I want to preprocess these points somehow faster than O(n^2) (O(nlog(n)) preferably), and then be able to answer on queries of the following kind "How many of n points lie ins...Learn MoreAlgorithmMathGeometry## Intersection of two lines defined in (rho/theta ) parameterization

Have created a c++ implementation of the Hough transform for detecting lines in images. Found lines are represented using rho, theta, as described on wikipedia: "The parameter r represents the distance betwe...Learn MoreMathGeometryimage-processing## wxPython Geometry problem

I'm trying to get the button to be right of the label. I set the tuple and am still not sure why it covers the label.

Freehand Drawing in Angular I wanted to something fun for the holiday season, so I decided to port a variable-width stroke from the Flex Freehand Drawing Library I created back in the early 2010’s. This stroke...Learn MoreJavaScriptNewsAngulartypescriptMathGeometry## Connect two Line Segments

Given two 2D line segments, A and B, how do I calculate the length of the shortest 2D line segment, C, which connects A and B? ...Learn MoreGeometry## Scripting A Hexagon Grid Add-On For Blender 2.91

This tutorial explores how to make a grid of regular convex hexagons in Blender with Python, then how to turn that script into an add-on. An example render made with the add-on looks like so: A grid rendered i...Learn MorePythonNewsGeometryBlenderCreative CodingHexagons## Nobody Is Brave Enough to Redesign the Waffle

In 1611, Johannes Kepler proposed a theoretical maximum density for packing spheres in 3D space.
