Percentage

The Percentage class is a simple class that allows to pass some parameters to filters as a Percentage of something (specified on the documentation of every filter). A Percentage object contains a single float value bounded between 0 and 100.

Here is a simple example of usage of the class:

ms = pymeshlab.MeshSet()
[...]
ms.generate_resampled_uniform_mesh(cellsize=Percentage(2.0), offset=Percentage(2.0))

In this case the filter will make an uniform resampling of the input mesh using a grid with a cell size of 2% of the diagonal of the bounding box of the mesh. This class is necessary to distinguish between relative Percentage values and absolute values (which are of type :ref:`absolute_value`).

Check the :ref:`apply_filter_parameters_percentage` tutorial for further examples.
