Category:Data operations

In Polaris Viewer an algorithm to process a data object or geometry object is called a filter. This is the naming convention used in ParaView.

Data operation must be applied on one or several existing data objects (input to a filter). It then produces a new data object in most cases. To use filter, user shall first click on the input data object in the "Pipeline Browser", then choose the appropriate filter to apply. If a filter cannot be applied to the selected data object this filter will be disabled (not applicable).

The output of a filter is another data object which can be used as inputs to subsequent data operations/filters. Sometimes several filters are applied consecutively to get desired results. These filters and the original data objects forms a pipeline of data and operations.
