<div dir="ltr">Hi Salazar,<div><br></div><div>Here are some steps to use it.</div><div><br></div><div>1). Load surface data.</div><div><br></div><div>2). If your surface consists of cells other than triangles, triangulate the data with a Triangulate filter.</div><div><br></div><div>3). Create a Poly Line Source. It will start with 2 points.</div><div><br></div><div>4). Place the points in the Poly Line Source on the triangulated surface. Select which point you want to place in the list by clicking its row, move your mouse cursor over the surface where you want the point to be places, then press the 'p' key. The selected point to jump to the surface point under the mouse cursor. Repeat for the second point.</div><div><br></div><div>5). Select the surface data source. Add a Geodesic Measurement filter. Set the Input to the triangulated surface data source and Endpoints to the Poly Line Source. Click Apply.</div><div><br></div><div>6). The geodesic path should be produced by the filter and can be visualized as any other poly data with line segments. In addition, the output has field data that contains the length of the path. You can view this by creating a SpreadSheet View and selecting the output of the Geodesic Measurement filter - Field Data in the spreadsheet view options.</div><div><br></div><div>HTH,</div><div>Cory</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Oct 11, 2016 at 5:18 PM, Salazar De Troya, Miguel <span dir="ltr"><<a href="mailto:salazardetro1@llnl.gov" target="_blank">salazardetro1@llnl.gov</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>Hello </div>
<div><br>
</div>
<div>I loaded the Geodesic Measurement plugin with the Plugin Manager, but I do not know how to use it. I see it as a filter option, but it is disabled even for point-based data. I haven’t been able to find an example either. I am interested in finding the
shortest path between two points in a surface.</div>
<div><br>

<div>Thanks</div><span class="HOEnZb"><font color="#888888">
