<p class="MsoNormal">Hi all.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Curious if there is any interest in supporting Leica PTX files in pdal. See more about the format here:
<a href="http://paulbourke.net/dataformats/ptx/">http://paulbourke.net/dataformats/ptx/</a> . It’s a plain text format with one or more header:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">number of columns<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">number of rows
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">st1 st2 st3 ; scanner registered position
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">sx1 sx2 sx3 ; scanner registered axis 'X'
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">sy1 sy2 sy3 ; scanner registered axis 'Y'
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">sz1 sz2 sz3 ; scanner registered axis 'Z'
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">r11 r12 r13 0 ; transformation matrix
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">r21 r22 r23 0 ; this is a simple rotation and translation 4x4 matrix
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">r31 r32 r33 0 ; just apply to each point to get the transformed coordinate
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">tr1 tr2 tr3 1 ; use double-precision variables
<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">followed by X, Y, Z and optional Intensity, R, G and B data. Similar to PTS.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m pretty sure this is an old out of fashion format, not sure many people would get use out of it. But since there is a PTS reader already I thought I’d maybe ask around.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We had a request to support it in our application and I rolled my own simple PTX reader plugin. I would give it some minor code clean ups first, but I’m happy to pull request it. I don’t have a writer though unfortunately
