The PercentageValue 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 PercentageValue 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=PercentageValue(2.0), offset=PercentageValue(30.0))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 pure_value).
