<div dir="ltr">Hi Ric,<div><br></div><div style>you are correct those wiki example seems to be out of date specially since the modularization of VTK where all the libraries have been renamed and shift around. </div><div style>
<br></div><div style>The best place to look for up-to-date examples is in the vtk.jar itself which should contains a set of sample code with the proper usage of rendering and GC classes as well as the loading of the libraries. </div>

In the example Cone2.java, the loading of libraries is significantly different:</div><div style="font-family:Verdana,sans-serif"><br></div><div style><font face="Consolas"> // Load VTK library and print which library was not properly loaded</font></div>

As it turns out, only the example Cone2.java uses the "correct" method for loading the libraries. Am I correct in assuming that Cone 1 and Cone3-5 are simply out-of-date with respect to VTK 6.0.0? Or am I missing something?</div>
<div style="font-family:Verdana,sans-serif"><br></div><div style="font-family:Verdana,sans-serif">I also note that only the simple "Sample" folder with its Cone examples even has Java implementations. I guess I am on my own to convert the examples to Java myself (which is fine, that will be a good learning exercise) or will that be a Quixotic effort on my part, tilting at an incomplete Java windmill?</div>
