title: What is a linear / angular deflection in OpenCASCADE's Incremental Mesh?
body: <p>Lately I've been using OpenCASCADE (PythonOCC, to be precise) for some CAD operations, including meshing shapes, and stumbled upon this class: 
  <a href="https://cdn.rawgit.com/tpaviot/pythonocc-core/3ceb6b92/doc/apidoc/0.17.3/OCC.BRepMesh.html?highlight=incrementalmesh#OCC.BRepMesh.BRepMesh_IncrementalMesh" rel="nofollow noreferrer">BRepMesh_IncrementalMesh</a>.</p>
  
  <p>I didn't find any hints on what the <code>theLinDeflection</code> and <code>theAngDeflection</code> parameters mean - and would like to know more about this.</p>
  
  <p>I would appreciate any reading materials / hints / explanations on this subject.</p>
