Implicit Surface Intersections

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... read more >>

GraphicsSmoothing and AlignVertexCenters

GraphicsSmoothing and AlignVertexCentersIn R2014b we introduced a new property on the figure named GraphicsSmoothing. When this is set to on, all of the graphics drawn into that figure are drawn... read more >>

Stacked Bar3

Stacked Bar3MATLAB's bar3 command is kind of cool, but what if we have a 3D matrix like this?rng(0) array = randi(10,[4 5 3]); It might be nice to create something that was sort of a stacked... read more >>

Object Creation Performance

Object Creation PerformanceBack in January, we looked at the performance of creating a graphics object with a lot of data. Today we're going to look at what is basically the opposite problem. What... read more >>

Patch Work

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... read more >>

State Taxes

If you live in the US, you probably filed your taxes sometime in the last couple of months. If you're like me, that got you looking at data about taxes. One nice source of tax data is the US Census... read more >>

How the Tiger got its Stripes

But I think that my favorite Turing paper is one he wrote after the war called The Chemical Basis of Morphogenesis. It describes an idea he had for how all of the different patterns on the skins of various animals are formed. It's really a very simple idea. You have two chemicals which are distributed nonuniformly through the skin of the animal. They react with each other, and they each diffuse from areas with high concentrations to areas with low concentrations. It turns out that fiddling the reaction rates and the diffusion rates can yield all sorts of different patterns which look very similar to patterns you see in nature.... read more >>

Implicit Curves & Surfaces

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... read more >>

Area Scaling

Last time we looked at how the performance of MATLAB's graphics system scales with the number of data points. Another interesting lens to look at performance scaling with is the way that performance... read more >>
