Like most computer graphics programmers, I've always been fascinated by the different types of regular tilings of the plane. There was recently some very big news (NPR, the Guardian) in the tiling... 続きを読む >>

Implicit Surface IntersectionsWe talked about implicit surfaces here back in March. Recently, there was an interesting question about them on MATLAB Answers.Dr. Vyas has a surface which is defined by... 続きを読む >>

Patch WorkBack before the internet, programmers collected xeroxed copies of old notes and papers. We traded these with our friends and coworkers, like samizdat. I still have a large filing cabinet... 続きを読む >>

Implicit Curves and SurfacesIn some earlier posts ( part1, part2) we explored how to draw parametric curves using MATLAB Graphics. Now lets turn our attention to implicit curves.We know that the... 続きを読む >>

The ribbons we created last time are nice, but sometimes we want something a bit more solid. Something like a tube.... 続きを読む >>

Tie a Ribbon Round It (Parametric Curves: Part 1)Parametric curves are easy to draw in MATLAB. For example, we can use the parametric equation for a circle like so:t = linspace(0,2*pi,128); x =... 続きを読む >>

PretriangulationAn interesting question went by on MATLAB Answers the other day. I've simplified it a bit here, but it looked something like this:rng(0) cla nfaces = 5000; nsides = 6; nframes =... 続きを読む >>

What is a Surface?What exactly is MATLAB doing when we say the following?surf(peaks)The answer seems obvious. We're telling MATLAB to draw a continuous surface through the points which are defined in... 続きを読む >>

Bézier Curves and Kronecker's Tensor ProductLast time we talked about Martin Newell's famous teapot. Today we're going to talk about the curves which the teapot is made of. These are known as... 続きを読む >>

Welcome to our new blog. My name is Mike Garrity, and I work in the group which develops MATLAB's graphics system. In R2014b, we've released a new version which we've been working on for a while now.... 続きを読む >>
