Is it possible to change the stroke width of a stencil line draping feature at run-time? If possible, I'd like to be able to decrease the width of the line as the user zooms in so that it doesn't become this big fat line close to the surface.
The way Google Earth does their roads is a good example of the effect I'm looking for.
Well, it's *possible*, but probably inadvisable depending on how much data you have. In the stencil driver, the stroke width translates into the width of the stencil volume cap, which is constant. If you change the style the symbolizer will have to regenerate all the stencil volumes - kind of a heavyweight operation.
