title: Analyze 3D objects by Voxels
body: <p>I plan to use OpenVDB to analyze 3D objects/meshes. The objective is:</p>
  
  <ul>
  <li>To detect object surface regions with a certain criterion, like slope</li>
  <li>Then manipulate those regions</li>
  <li>The manipulation might be adding other 3D objects to those regions, for example</li>
  </ul>

  <p>OpenVDB has some <a href="https://www.openvdb.org/about/" rel="nofollow noreferrer">tools</a> available:</p>
  
  <ol>
  <li>Conversion Tools</li>
  <li>Filters</li>
  <li>Topological Operations</li>
  <li>Level Set Tools</li>
  <li>Morphological Operations</li>
  <li>Geometric Transforms</li>
  <li>Compositing Tools</li>
  <li>...</li>
  </ol>
  
  <p>It is a large set of confusing tools to choose from. Does anybody with OpenVDB experience know:</p>
  
  <ol>
  <li>Is OpenVDB the proper library to achieve my objective</li>
  <li>If so, which OpenVDB tool best suits my needs</li>
  </ol>
