Hi All,

There seems to be quite a few Renderer implementation , LiteRenderer, LiteRenderer2, StreamingRenderer .

StreamingRenderer appears to be the final "name". This is part of the end of series of LiteRenderer, LiteRenderer2. They are trying to set up a common API that "optimized renderers" (like ShapefileRenderer) can also support.

Am in the process of developing an application using GeoTools and confused as to which renderer to use.

Can someone please let me know which renderer is feature complete ?

Currently StreamingRenderer is your best bet, although for an interactive application the J2DRenderer is also a good choice. If you buffer your features into a MemoryDataStore you can obtain similar levels of performance from StreamingRenderer.

What kind of application are you making? The nicest system is something similar to uDig (or the GeoWidgets project) that makes the decision on which renderer to use based on area of interest and styling information.
