MATLAB 2012 COLORBAR TITLE CODE

In my introductory post last week, I showed you a few visualization examples using jet, and I asked you some questions about them. Here is jet, the MATLAB version: showColormap( 'jet', 'bar')

Multiple methods exists for constructing rainbow colormaps, so they don't all look alike. Biv' for remembering the order of colors: red, orange, yellow, green, blue, indigo, and violet. Some of you might know the mnemonic 'Roy G. A rainbow colormap is based on the order of colors in the spectrum of visible light. This week I want to explain some of the motivations for replacing jet. Parula has replaced jet as the default colormap in R2014b, which was released earlier this month. And copying on top of /Applications/MATLAB_R2011b.app/sys/fonts/ttf/cm/mwa_ week I showed you the new MATLAB colormap, parula. I fixed this by finding cmss10.ttf on the web.

Then choose Select > Same > Stroke Weight. Select one of the РІР‚СљdotРІР‚Сњ markers (especially visible if any of your lines were very small). Inevitably, matlab will have saved much more than just the line segments. HereРІР‚в„ўs my updated pipeline for making nice images of vector field using MATLAB and Adobe Illustrator. This is fine for prototyping, but not great for making nice images. This function creates РІР‚СљarrowsРІР‚Сњ using three line segments.

Is much slower to render and interact with than to just draw a bunch of degenerate triangles using: trisurf(,N(:,1),N(:,2),N(:,3)) set(gcf,'Renderer','OpenGL') Р”Р„wkwardly, plotting a bunch of (disconnected) line segments from vertices in N and edge indices in E in matlab using something like: plot3(',',','k') Whereas first setting the renderer to the GPU renderer 'OpenGL' is much faster. Where X and so on are very large can take a long time (say 1 minute).

Matlab seems to default to its CPU renderer 'painters' when creating new figures with scattered dots or lines. Tags: 3d, ambient occlusion, geometry, gptoolbox, lighting, matlab, plot, rendering, shading

If the code for my research is already written in MATLAB then one huge advantage is that every image in my paper can have a *.m script that deterministically generates the result and the corresponding image with user intervention. This started as a way to just make images from research prototypes more palatable, but eventually became the usual way that I render images for papers. Over the years, IРІР‚в„ўve developed a way of creating plots of 3D shapes in MATLAB using a few extra functions in gptoolbox. Other tools like Mitsuba can create beautiful pictures, but can feel quite cumbersome for rendering pure geometry rather than the physical scenes their designed for. However, the learning curves for most commercial rendering tools are quite steep. MATLAB is not a great tool for creating 3D renderings.
