Re: [Geotools-devel] Geometry transformations ready to roll

The are more things that can be done creatively using the
existing filter functions, and many more that can be done implementing
your own new functions, but I hope this shows the potential of this
new development.

Speaking of other stuff that can be done with transformations, what
do you think of the attached trick? ;-)

First the base is drawn, then an isometric extractions of the wall is
painted, and then a lighter rooftop is added using offset.
I've tried to use a single function but the root needs to be a different
color, so no go.
If I add the ability to specify an extrusion angle other than 90° I 
guess it will be better to have two functions, isometric_walls and
isometric_rooftop to extract the root without having to compute
the offset with trigonometric functions.

Cheers
Andrea
