Creating new filters

New filters for ZeoGraph may be created in one of two ways:

1. Creating a ZFILTER text file to define the filter behaviour using scripts (see link for more info).
2. Creating a binary plugin using the Zeolite plugin API and the ZeoGraph wrapper classes, which are available on request.

The ZFILTER approach is generally recommended for creating new filters, as the text files are more easily created than binary plugins. However, such filters are restricted to using only the operations and calculations that are supported by L3DT or its plugins. Thus, creating filters via plugins is recommended for instances where new filters are required to perform calculations not already supported by L3DT or other plugins.
