File Exchange Pick of the Week

Moving 3D Objects Interactively

Jiro's pick this week is "Moving 3D Objects with Mouse" by Gang Wang.

I like this demo entry, because it shows you how you can interactively manipulate graphics object in MATLAB. Visualization is one of MATLAB's strengths, but not many people know that you can create interactive visualizations as well. The key is to make use of some of the callback functionalities, such as WindowButtonMotionFcn for a figure. Take a look at the subfunction "movit" in Gang's code. That's where all the magic happens.

I would also like to give mention to the 2D version (by Anders) that Gang was inspired by.

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
