Class: Filter

.plugin. Filter

Creates a new filter


new Filter(parameters)

This class provides the basic method for adding new processing functionalities to meshlabjs. The main idea is that a filter is a kind of blackbox processing function that take in input meshes (eventually none) parameters and give back processed meshes. When you add a filter to meshlab it will end up in the filter list tab. You have to redefine three functions:

  • the constructor
  • the _init where you define the parameters
  • the _applyTo where you define the behaviour of the function
Name Type Description
parameters Object

The object contains the initialization parameters to create filter plugin

parameters = {
  name: //the name of filter
  tooltip: //the filter description shown if mouse pointer is over its name
  arity: //An integer:
     //0 for a creation filter
     //-1 special value for the deletion filter, doesn't trigger      a layer update event      //1 for a generic single mesh filter, e.g. a filter      that takes a mesh, some parameters and modify just that single mesh.
     //2 for a filter that take one or more mesh and/or create other layers.      //3 for a filter that works on all visible layers.

defines its own meshes

Refine Filter

         iterWdg = builder.Integer({
