Hi,<div><br></div><div>What you want to do is derive a new class from vtkGeometryRepresentation and than override the member variable Decimator with your own LOD algorithm. You will than need to change all objects to use your new representation, or create a new view where this representation is used.<br>

Instead of modifying the underlying LOD algorithm, what about turning<br>
off the LOD, and create a new type of representation for your data<br>
with the small vtkUnstructuredGrid? and of course, you have to change<br>
the representation to this new type during mouse interaction.<br>
