Steve,
I like this idea. I opened an enhancement request against 6.0, I realize
it probably will not make the freze, so push it to future or whatever.

Maybe this is a GEOMTRANSFORM function in 6.0 speak? You could do
something like:
GEOMTRANSFORM (extrude(some view parameters, [height]))
Where the first few arguments define a view position and the last
argument is height. Neat thing about this approach that height could
be a constant or a bound to an attribute. The extrude function would
generate the sides, top and bottom based on view parameters and a
height. It could even (perhaps) create multiple features mirrored on
the outline but with extended attributes that would define things
like top vs. side vs. bottom, or whether a facet side is visible or
not.
If done outside of STYLEs (e.g. a layer-level GEOMTRANSFORM) then one
could draw things differently based on these pseudo attributes (e.g.
if a side and visible do this).

Hi all,
Has anyone been able to render 3D building with mapserver?
I have a polygon layer with the building outlines and a height
attribute.
Any thoughts on how to render nice buildings like Google does?
I can preprocess the data and extrude it into 3D shapes, but I'm not
sure that gets me anywhere.
My one thought was to draw the polygon, then draw it again with an
xy offset based on a function of the height. But this does not
generate the vertical edges of the building.
I suppose I could generate all the vertical faces and the top of the
build and then sort them all based on the z value of the centroid. I
could event remove all the back facing polygons faces.
It would be cool if mapserver had:
LAYER TYPE POLYGON3D HEIGHT [height] ... END
Thoughts? -Steve W _______________________________________________
