                    WARNING     Anyone well acquainted with computer graphics can spot specific pieces of entourage
                       that seem to get used over and over again by beginners. Chances are, any free entourage you can find
                       on the Web has been used countless times by others looking for an easy way to dress up their ren-
                       derings. Your best bet is to either make or buy quality entourage. Your renderings will appear more
                       professional.

                    Entourage in Autodesk VIZ
                    Using entourage in a 3D program is simple in concept, but often difficult in practice. We will look at
                    the procedure for setting up entourage in Autodesk VIZ 2005. The steps are similar in other versions
                    of VIZ and 3ds max. The concepts you learn here will apply in other 3D programs, although the steps
                    may be different, depending on the features of the software.
                       The main idea is that you take the photographic entourage you create in Photoshop and use it in
                    a material that you design in VIZ. This material defines the surface qualities of a 3D object and uses
                    both the color pixels and alpha channel of the entourage file. You map this material to the surface of
                    plane geometry to create the illusion of a 2D cutout in a 3D scene.

                    Creating Entourage Geometry
                    The first order of business is to make a flat object onto which you’ll later map a material. Although any
                    flat geometry will do, an object that has the correct orientation and pivot point location for ease of
                    manipulating the object in a 3D scene is better. Follow these steps:
                       1. Launch Autodesk VIZ 2005. Choose Customize   Units Setup to open the Units Setup dialog
                          box (see Figure 4.36). Click the US Standard radio button; select Feet w/Fractional Inches in the
                          drop-down, select 1/8 in the precision drop-down, and click the Feet radio button to set
                          Default Units. Click OK to close the Units Setup dialog box.
