Deke's Techniques #19: Splitting and modifying repoussé objects

Last week in Deke’s Techniques, lynda.com author Deke McClelland showed you how to take a flat pie graph from Illustrator and turn it into a 3D chart in Photoshop. And this week, we’ll see how that chart is taken to the next level—literally—as Deke demonstrates how to give each slice its own depth and color. The first step is to divide the pie into individual slices, creating a 3D mesh for each object so that you can apply attributes to each piece. And while you may not want to contemplate something as questionable as tuna fish pie, the technique you’ll see here can be applied to your own 3D objects and give your business graphics that extra flavor (as seen below on the right).

Deke starts where with the extruded pie he created last week (left), and colors each slice individually by changing their Diffuse colors in the 3D materials panel and then place them in 3D space with the 3D Mesh panel in Photoshop CS5 Extended. Although it sounds complicated (at least to my stubbornly 2D mind), watching Deke step by step can help you find your bearings in 3D space. And if you’d like to see more about the 3D capabilities of Photoshop Extended, Deke’s got a full-course menu of 3D courses available now inside the Online Training Library®. Photoshop CS5 Extended One-on-One: 3D Fundamentals covers the basic techniques for working with 3D in Photoshop, showing how to create textured type and drawing objects that can be manipulated in 3D space. The second course in the series, Photoshop CS5 Extended One-on-One: 3D Objects, covers how to draw six varieties of volumetric objects and manipulate them in 3D space. And stay tuned for more courses featuring Deke in 3D.

Every week, there’s a new free technique from Deke. And lynda.com members can see the entire Deke’s Techniques collection here, including exclusive members-only videos. In fact, this week, Deke reveals another cool feature inside Photoshop extended known by the fabulously whimsical name of Ground Plane Shadow Catcher, which allows you to create a versatile shadow for your 3D object, as you can see here:

And we’ll see you back here next week for another free technique from Deke!
