On my 10.7 machine the default site location is at /Library/WebServer/Documents/index.html.en You should be able to edit this file and see that http://localhost/ changes.

Now, we’d like to have an arbitrary folder contain our website, so I’ll use ~/Documents/IGL-website. Copy your websites source or put some source in this folder.

Now we setup the redirect necessary to send some local domain name (we’ll use localigl to our website at ~/Documents/IGL-website. Open up the file /private/etc/hosts and add the line:

127.0.0.1       localigl

Now you should see that going to http://localigl/ also directs to /Library/WebServer/Documents/index.html.en

Now edit the file
/private/etc/apache2/users/YOURUSERNAME.conf
and add the following:

NameVirtualHost *:80

<Directory "/Users/YOURUSERNAME/Sites/">
    Options Indexes MultiViews Includes
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot /Users/YOURUSERNAME/Sites/
</VirtualHost>

<Directory "/Users/YOURUSERNAME/Documents/IGL-website/">
    Options Indexes MultiViews Includes
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

<VirtualHost *:80>
    ServerName localigl
    DocumentRoot /Users/YOURUSERNAME/Documents/IGL-website/
</VirtualHost>

You’ll need to add executable permissions to the path preceding your website, so for my example this means:

chmod +x ~/Documents

To get php scripts working correctly, in /private/etc/apache2/httpd.conf uncomment the following line to look like this:

LoadModule php5_module libexec/apache2/libphp5.so

Now, you must restart your apache server. The easiest way is to toggle System Preferences > Sharing > Web Sharing.

With all this, you should now be able to go to http://localigl/ and see your (possibly php-based) webpage.

Finally instead I found the way to quickly change the URL at the top of the web search to switch it to a scholar search. If this is your web search url:

http://www.google.com/search?hl=en&client=safari&rls=en&q=Fast+Automatic+Skinning+Transformations&oq=Fast+Automatic+Skinning+Transformations&aq=f&aqi=p-p1&aql=&gs_l=serp.3..35i39.2032.2203.0.2388.2.2.0.0.0.0.70.124.2.2.0...0.0.wzP9uU0hsCc

just replace search with scholar

http://www.google.com/scholar?hl=en&client=safari&rls=en&q=Fast+Automatic+Skinning+Transformations&oq=Fast+Automatic+Skinning+Transformations&aq=f&aqi=p-p1&aql=&gs_l=serp.3..35i39.2032.2203.0.2388.2.2.0.0.0.0.70.124.2.2.0...0.0.wzP9uU0hsCc

My colleagues, Ilya Baran, Ladislav Kavan, Jovan Popović, Olga Sorkine, and I have just submitted the camera ready version of paper “Fast Automatic Skinning Transformations” to be presented at ACM SIGGRAPH 2012. I’ve put up a fast automatic skinning transformations page where you can find the preprint version of the article, videos and more to come.

Abstract

Skinning transformations are a popular way to articulate shapes and characters. However, traditional animation interfaces require all of the skinning transformations to be specified explicitly, typically using a control structure (a rig). We propose a system where the user specifies only a subset of the degrees of freedom and the rest are automatically inferred using nonlinear, rigidity energies. By utilizing a low-order model and reformulating our energy functions accordingly, our algorithm runs orders of magnitude faster than previous methods without compromising quality. In addition to the immediate boosts in performance for existing modeling and real time animation tools, our approach also opens the door to new modes of control: disconnected skeletons combined with shape-aware inverse kinematics. With automatically generated skinning weights, our method can also be used for fast variational shape modeling.

Update: The full resolution version of the above teaser.

Update: The accompanying video (with narration)

ids = mod(indices,n)+1

Which plotted as a function of the indices looks like a sawtooth wave:

Another way to get non-repeating numbers, with near-equal distribution is to use a triangle wave, counting up to n and then back down to 1 and repeating:

ids = abs(mod(indices,n*2-2)-n+1)+1

which looks like:

D = whos();
D = D(arrayfun(@(d) strcmp(d.class,'yourclassname'),D));
clear(D.name)

convert screencapture-*.tga screencapture.gif

This made an animated gif with transparency, but each frame showed the previous frames behind it. Resulting in something like this:

The magic keyword seems to be “dispose” and calling the following fixed my problem:

convert -dispose 2 screencapture-*.tga screencapture.gif

which results in:

Then I can underlay a background image and get something like:

Abstract
By embedding images as surfaces in a high dimensional coordinate space defined by each pixel’s Cartesian coordinates and color values, we directly define and employ cotangent-based, discrete differential-geometry operators. These operators define discrete energies useful for image segmentation and colorization.
