The Hook and Snake tools, for instance, enable you to pull, stretch, and literally "snake" any part of your image in any direction and depth. You can then isolate any object and further modify it using the painting tools by pulling and stretching the object's surface. For instance, you can place primitive objects, such as spheres and cylinders, in your image one by one. In addition to painting, you can use ZBrush as a basic modeling application. It would be nice if ZBrush also supported different mapping types as well as the ability to use texture maps, however. The software also includes stock materials that you can modify by changing parameters such as ambient, diffuse, specularity, transparency, and reflectivity. Materials also are supported, and you can modify them after you apply your brush strokes to radically change the look of your image. This gives you a great deal of freedom in determining how your final image will look. ZBrush has a basic lighting palette that enables you to change parameters such as color, intensity, and direction of light sources. All these tools make ZBrush rather addictive.īecause the images created in ZBrush have a 3D component, you also can affect their lighting. The software also features several brushes geared specifically for 3D, such as a brush that makes a surface bumpy, and an alpha channel brush for painting transparency. By opening up the Brushes palette, you soon realize that you can paint with a number of 3D objects in addition to spheres, including basic primitives such as cylinders, cones, and toruses.ĭelving deeper, you'll discover that even features such as the Smudge tool work in 3D, actually distorting and blending the 3D surfaces of objects. Instead of a normal glop of paint, ZBrush lays down sphere-like objects that have shading, texture, and depth. After you begin painting, however, you start to notice the difference between regular 2D painting programs and ZBrush. The software provides a number of floating palettes for picking brushes and color, which should seem familiar to anyone who has ever used a paint application. ZBrush's interface doesn't use familiar Windows or Macintosh menus and toolbars, but it nonetheless makes painting in 3D fairly easy.ĭigging into the application, I found myself able to immediately use the paint tools. I found it fairly easy to learn the interface and become productive with the software. Keeping the images against black is a good idea, as it gives users a clearer view of what their final art will look like. Upon launching, the software presents the user with a mostly black screen, with white and gray icons and floating palettes. Instead, Pixologic has developed its own look and feel for the application that reminds me a bit of high-end Unix systems such as Discreet's Flame. Unlike most Windows applications, for instance, ZBrush has no standard toolbar or drop-down menus. The product's interface is not standard to either platform. The software runs under Windows, but a Macintosh version is currently in beta. By keeping objects in three dimensions, ZBrush also allows for the creation of lighting and material effects. This means that each pixel also carries depth information, which makes it easy to place objects in front of or behind other objects. In fact, ZBrush brings a whole new way of thinking to the digital painting process.Īt the core of ZBrush is a technology called Pixol, which interprets each pixel in an image three dimensionally. This makes ZBrush innovative and fun to use. In practice it lies somewhere between a 2D painting package and a 3D modeling program in that you use a traditional 2D brush to paint with fully rendered 3D objects. Pixologic's ZBrush is the first new painting application I've seen in a long time.
