<p>Libigl is a C++ library, but its functional interface make it very friendly to
wrapping individual functions for popular scripting languages like Python or
MATLAB. Since many libigl functions have the form &#8220;mesh in&#8221; &#8211;&gt; &#8220;mesh out&#8221; or
&#8220;mesh with scalar field in&#8221; &#8211;&gt; &#8220;scalar field out&#8221;, we would like to develop an
<em>automatic</em> routine for generating Python and MATLAB bindings for libigl
functions. This project has three parts: 1) determining the necessary mark up
(e.g. comments) inside libigl header files to determine the Python interface,
2) writing a program to parse this mark up and generate valid Python bindings
and compilation instructions, and 3) validating and testing these results on a
variety of functions in the library.</p>

<p>Libigl avoids complicated mesh data-structures to ensure that its interface is
clean and easy to port into users&#8217; existing projects. Our mesh format is a
simple list of vertices and list of face indices to those vertices: <code>V</code> and
<code>F</code>. We have a number of functions for <em>deforming</em> a mesh: that is, modifying
the entries in <code>V</code>, but currently lack functions for <em>modifying</em> the mesh&#8217;s
topology: that is, modifying <code>F</code> and/or modifying the <em>size</em> of <code>V</code>. This
project entails implementing <em>efficient</em> routines for: edge collapse, edge
splitting, and edge flipping. The project will culminate in a routine combining
these core functions for surface remeshing.</p>
