THE CREATION OF 3D SITES offers al l the chal lenges that come with 2D sites but with numerous addit ional dif f icult ies. When creating 2D sites using the methods described in the previous chapter, you don’t have to worry as much about things such as gaps or holes between different elements, facets appearing on the various surfaces, adjacent faces overlapping, or any number of other problems that 3D terrain modelers have to contend with on a regular basis. You also don’t have nearly as much site data to interpret, prepare, import, and manage. For moderately sized projects, things l ike cleaning and preparing poorly constructed topographical l ines could add hours to your work.
