<h2>Generating curved fingerprint model<a class="headerlink" href="#generating-curved-fingerprint-model" title="Permalink to this heading">#</a></h2>
<p>It is possible to generate stl model using the <cite>–stl</cite> switch. This requires more parameters, first of which is the type of generated fingerprint.</p>
<p>If the mode is set to <cite>c</cite>, the output model will be a curved finger model, with optional parameters following the filename controlling its shape.</p>
<p>First optional parameter is papilar line height <cite>height_line</cite>, second is thickness of the model <cite>height_base</cite>,
third the rate of curvature along x axis <cite>curv_rate_x</cite> and the third is the rate of curvature along y axis <cite>curv_rate_y</cite>.</p>

<h2>Mapping fingerprint to existing finger model<a class="headerlink" href="#mapping-fingerprint-to-existing-finger-model" title="Permalink to this heading">#</a></h2>
<p>Using <cite>m</cite> mode modifies the preexisting finger model to contain fingerprint.
First optional parameter is papilar line height <cite>height_line</cite>, second is the number of iterations <cite>iter</cite> to make the finger mesh denser. Higher number of itertions results in denser finger mesh and better result.
The last three parameters are axis offsets for the finger, <cite>finger_x</cite>, <cite>finger_y</cite>, <cite>finger_z</cite>.
These control the location of the finger. They need to be set only if the user wants to move core of the print closer to the center of the finger.</p>
