3D Effect for 2D Building polygons
I am trying to recreate the effect that is shown in the attached file. The buildings appear to be "floating" which simulates a somewhat 3D effect but also there is a gradient of color based on the roof line. That is, on one side of the roof the color is slightly lighter as compare to the other side of the roof.
Mapping Center Answer:
There is quite a bit going on in the referenced illustration that acomplishes the building effect. First is the drop shadow and for that we already have document on Mapping Center that you can use the same steps to make a dropshadow for you buildings. The one caveat is that ArcMap cannot yet do the fuzzy transparent drop shadow without a lot of extra work.
Next there are several effects with gradients being used on the roofs. In a few cases it is just a simple circle style gradient. For the yellow roofs that show the hip joints, you will need polygons for each facet on each roof--code them by which side they are on and then you can assign a color to each side to create the effect.
Some of the burgundy roofs are using a blend effect to diffuse the change in color in middle. You will need to use a three polygon approach (like the yellow roofs) except that the three polygons will be set up such that two wider polygons sandwich a narrower polygon. The wide polygons get solid fills, while the narrower polygon gets a gradient fill that blends between the two wider polygon's colors.
