I like this idea, but anyway it is implemented I think it would be a
good feature to have.
Beyond OSM, I have run into quite a few people that are generating data
sets with building outlines and some of them have height info. A lot of
this data is getting generated from plot plans and tax roles where the
number of floors is included which can be interpreted as height.

Probably a bit of overkill for what amounts to a visual effect. I was
thinking about this a bit more this evening and wonder if we could
use the GEOMTRANSFORM functionality and create an "extrude" geometry
transform. A little trickier than the ones currently supported since
this one would produce multiple shapes rather than a single
multi-polygon. Would be kinda neat though and totally self contained.
Think about turning a line into a curtain for instance.

Looks a bit like Sketchup. How about a driver for Sketchup 3D? It has
already input- en output facilities for DXF and DEM

I can't tell from the example but it doesn't look like the map itself
is oblique rather that the buildings are drawn in 2.5D.
If so, this probably can be reduced to a data pre-processing
exercise. I created a small test case (see attached) where a the
pieces of a cube are drawn by MapServer. It was quick and dirty but
it shows MapServer can possibly render like the example you
referenced. Key is producing the cube (sides, top, and bottom) data.
I would expect that could be done ahead of time via a script where
you offset the footprint in the y direction by a height value and
then compute the sides- each as a separate shape. I suppose it would
be possible to create a plugin layer for this type of data (footprint
+ height) but easiest route is probably data pre-processing....
Something to try anyway.

Your effect is shadow like effects, not the "cube" like effect.

Just found a web site today. The map looks pretty like Google map,
except that it's not on Google. Can map server do this? Or anyone has
any idea which application can render this kind of image?
I got a similar result using opacity and offset with MapServer. See
