# Incremental Delaunay Construction

Posted by Loren Shure,

I'm happy to welcome back Damian Sheehy as guest blogger. Last time Damian wrote about how Natural Neighbor interpolation addresses FAQs in scattered data interpolation. In this blog he will answer a FAQ on adaptively editing a Delaunay triangulation.... read more >>

# Natural Neighbor – A Superb Interpolation Method16

Posted by Loren Shure,

I'm happy to welcome Damian Sheehy as this week's guest blogger. Damian works on the development of geometry-related features at MathWorks. He will provide answers to two frequently asked questions; one on scattered data interpolation that he will cover in this blog and the other on Delaunay triangulation that he will cover in the next. Over to you, Damian...... read more >>

# Intersecting Lines (Part 2)2

Posted by Loren Shure,

Recently, Lucio and I wrote a post on detecting line segment intersections. We confessed in the post that we had not been exhaustive in our treatment. We also received many interesting comments. This post introduces a 3rd method, one that... read more >>

# Intersecting Lines18

Posted by Loren Shure,

Today I am writing this post in collaboration with my friend and colleague, Lucio Cetto. Ever need to know if two line segments intersect? There are lots of ways to do this, and I thought I would show a few solutions ... read more >>

# Calculating the Area Volume Under a Surface13

Posted by Loren Shure,

Recently there was an email making the rounds at MathWorks about how to calculate the area volume under a surface. Not surprisingly, there were several methods chosen, based on each sender's proclivities. Here are some of the ways. ... read more >>

# Points and Polygons12

Posted by Loren Shure,

Ever wanted to know if some points of interest were inside a region? You can answer that if the region is specified as a polygon in MATLAB. The key is the inpolygon function. ... read more >>

# A Clear Conundrum7

Posted by Loren Shure,

Ever been in the situation where you accidently used a variable named something else in MATLAB and it caused you a problem? Ever done it with a variable named clear? It can be devilish to get out of the mess. Here... read more >>
