vtkBinnedDecimation is claimed to be a polygon mesh decimator with similar results to vtkQuadricClustering, but much faster and with a smaller memory footprint. It already appears in documentation ([https://vtk.org/doc/nightly/html/classvtkBinnedDecimation.html](https://vtk.org/doc/nightly/html/classvtkBinnedDecimation.html)). However, it’s not in the VTK 9.0.1 download. Does anybody know if and when it will be released?

Thanks!

The Nightly Documentation refers to the VTK master. `vtkBinnedDecimation` was first released on 2 June 2020 and VTK 9.0.1 was released on the 25 June so it may be that these files never made it into the release since a release is usually branched off the master at an earlier date. Unfortunately I am not sure when the branching happened.
