Hi, Don Murray,
The following two JPG file is the streamline with the previous
version(stream-1.jpg) and the new version(stream-2.jpg).
FlowControl cFlow = (FlowControl)streamUMap.getControl();
cFlow.setStreamlineDensity( 1.0 );
cFlow.setStepFactor( 0.5 );
The stream-1.jpg is what I want, but I have no idea about the stream-2.jpg
When I run the following code, there is something wrong. I paste the code and
errors:
