This chapter will describe the EnSight User Defined Reader Version 2.0 API. It was designed to be considerably more efficient than the 1.0 API and has a number of new features that later versions of EnSight can take advantage of.

If you are producing a new reader, or considering upgrading an existing version 1.0 API reader, please see the discussion on the philosophical differences between the two API's in User Defined Reader APIs

If you wish to convert an existing 1.0 API reader to the 2.0 API, see Converting a 1.0 API Reader to a 2.0 API READER.

The process for producing the dynamic shared library is described in How To Produce A User Defined Reader.
