Lesson 4 Map Artwork to 3D Objects ILLUSTRATOR 11-39 Art dialog box, shown in Figure 70, you must first choose which surface you intend to map the art to. When you click the sur- face buttons, the active surface is shown in red wireframe on the 3D object. In this example, we are mapping the wrapping paper to surface 1 of 4, which is shown in Figure 71. The grid pattern represents the complete surface of surface 1 of 4. Understand that this means not only the surface that you see—the front surface—but the entire surface, all the way around. For this exercise, we’re interested in mapping the wrapping paper to the surface that we can see—the front surface. That area is defined by the curved lines, identified in Figure 71. FIGURE 70 Map Art dialog box FIGURE 71 Identifying the surface to be mapped Last surface button Previous surface button First surface button Next surface button Interior of curved lines represents visible surface (1 of 4) ILLUSTRATOR 11-40 Creating 3D Objects Once you have chosen the surface, you then choose the symbol to be mapped by clicking the Symbol list arrow and select- ing the appropriate symbol. When you do so, the symbol artwork is centered on the grid. In this example, the symbol is named Wrapping Paper. For this exercise, we drag the artwork so that it completely covers the curved lines that represent the front face, as shown in Figure 72. Once the artwork is mapped, it reshapes itself to the three-dimensional object, as shown Figure 73.

Open AI 11-7.ai, then save it as Tea Can. 2. Select all, click Effect on the menu bar, point to 3D, click Revolve, then click OK. Your artwork should resemble Figure 74. 3. Open AI 11-8.ai, select all, click Edit on the menu bar, click Copy, close the document, then return to Tea Can.ai. 4. Click Window on the menu bar, click Symbols, click Edit on the menu bar, click Paste, then drag the pasted artwork into the Symbols palette to create a new symbol. 5. Delete the pasted artwork from the artboard. 6. Double-click the new symbol in the Symbols palette, type Elephant Rectangle in the Symbol Options dialog box, then click OK. 7. Open AI 11-9.ai, select all, copy the artwork, close the document, return to Tea Can.ai, then paste the artwork. 8. Drag the pasted artwork into the Symbols palette to create a new symbol, then delete the pasted artwork from the artboard. 9. Name the new symbol Elephant Circle. You used the 3D Revolve effect to create the artwork to which the 2D artwork will be mapped. You then created two symbols, one for each part of the 2D artwork. FIGURE 74 Creating the “tea can” and “lid” ILLUSTRATOR 11-42 Creating 3D Objects Map rectangular artwork 1. Click the Selection Tool , click the silver- object, then press  eight times so that the silver artwork is fully “under” the purple lid. 2. Double-click 3D Revolve in the Appearance palette to open the 3D Revolve Options dia- log box, click the Preview check box, then click Map Art. 3. Note that the Surface text box reads 1 of 3 and that a red line indicates that surface on the object, as shown in Figure 75. 4. Click the Next Surface button two times, so that the Surface text box reads 3 of 3. The light gray areas of the layout grid repre- sent the visible area of the silver object at this viewing angle. 5. Click the Symbol list arrow, then click Elephant Rectangle. 6. Drag the top-left and bottom-right resizing handles on the symbol’s bounding box so that the artwork fits into the light gray areas of the layout grid, as shown in Figure 76.

Drag the bottom-middle resizing handle up slightly so that the silver “can” will show beneath the “elephant label.” 8. Click the Shade Artwork (slower) check box. 9. Click OK, change the ambient light setting to 65%, change the highlight intensity setting to 80%, change the number of blend steps to 128, then move the light to the location shown in Figure 77. 10.Click OK, deselect all, then compare your work to Figure 78. In the Map Art dialog box, you selected the symbol that you wanted to map and the surface that you wanted to map it to. You resized the symbol artwork so that it fit onto the surface properly, then you activated the shading option to make the artwork appear more realistic as a label. You modified surface shading settings and lighting to improve the appearance of the artwork.

Click the purple “cover” object, double- click 3D Revolve in the Appearance palette, click the Preview check box, then click Map Art. 2. Click the Next Surface button once, so that the Surface text box reads 2 of 5. 3. Click the Symbol list arrow, then click Elephant Circle. 4. Point to the upper-right resizing handle until a rotate cursor appears, then drag to rotate the graphic to the position shown in Figure 79. 5. Click OK to close the Map Art dialog box, click OK again, deselect all, then compare your artwork to Figure 80. You mapped a circular piece of 2D artwork to an oval 3D object. FIGURE 79 Rotating the mapped art FIGURE 80 Viewing the mapped art Rotate cursor Lesson 4 Map Artwork to 3D Objects ILLUSTRATOR 11-45 Map texture artwork 1. Open AI 11-10.ai, select all, copy the artwork, close the document, then return to Tea Can.ai. 2. Verify that the Symbols palette is visible, click Edit on the menu bar, click Paste, then drag the pasted artwork into the Symbols palette to create a new symbol. 3. Delete the pasted artwork from the artboard. 4. Double-click the new symbol in the Symbols palette, type Cover Texture, then click OK. 5. Click the purple “cover” object, double-click 3D Revolve (Mapped) in the Appearance palette, click the Preview check box, then click Map Art. 6. Click the Next Surface button until the Surface text box reads 5 of 5. 7. Click the Symbol list arrow, then click Cover Texture. 8. Position the symbol artwork so that it covers the entire light gray area, shown in Figure 81. 9. Click OK to close the Map Art window, then drag the light to the location shown in Figure 82. 10.Click OK, deselect all, then compare your work to Figure 83. 11.Save your work, then close Tea Can. You mapped artwork to the front face of a 3D object to add texture. FIGURE 81 Positioning the artwork FIGURE 82 Relocating the light FIGURE 83 Viewing the finished artwork CHAPTER SUMMARY The key to creating 3-dimensional artwork is to understand the X, Y, and Z axes and be able to identify them on your illustrations. Then you can let the power of CS2’s 3D features do the work for you. By extending an object’s Z axis, you add three dimension to it. The 3D Extrude & Bevel Options dialog box allows you to add more detail to your object by choosing a bevel shape, adjusting the depth of extrusion, choosing a type of surface shading and manipulating light sources. You can also further adjust the X, Y, and Z rotations while previewing the changes you make. Revolving artwork is another way to create 3D art. Revolving artwork sweeps a path in a circular direction around the Y axis. Finally, mapping artwork is a way to “wrap” your illustrations around an object or shape. The Map Art button in the 3D Extrude & Bevel Options dialog box offers you a variety of ways to map your art to an object so that your artwork looks as if it’s wrapped around a 3D shape. Take time to experiment with the features in this chapter. You’ll be impressed with your results. What You Have Learned • How to extrude an object • How to extrude and rotate an object • How to extrude a compound path • How to apply a bevel shape to an object’s edge • Revolve an object • Revolve multiple objects • Revolve grouped objects • Offset a revolved object • Apply surface shading to a 3D object • Manipulate lighting controls • Manipulate light sources • Prepare a document for mapped artwork • Map rectangular artwork • Map round artwork • Map texture artwork Key Terms Two-dimensional object An object that has two axes: an X axis representing the width and a Y axis representing the height. Extrude To add depth to an object by extending it on its Z axis. An object’s Z axis is always perpendicular to the object’s front surface. Bevel The bevel is the angle that one surface makes with another when they are not at right angles. Revolving Revolving an object “sweeps” a path in a circular direction around the Y axis. Surface shading Surface shading controls how the object’s surface appears. When an object is revolved, four surface shadings are available: Wireframe, No Shading, Diffuse Shading, and Plastic Shading. Highlight Intensity Highlight Intensity controls how intense a high- light appears.
