Chapter 4. Surface Attributes > Surface Attributes

1. Surface Attributes

Set up surface attributes in the following sections. Creating objects that have a variety of surfaces is one of the many fascinating aspects of 3D computer graphics.

Process of Setting Up Surface Attributes

Although the entire object is now set up with surface attributes like white plastic or china, you can choose the color or surface appearance of the objects when you set the surface attributes on each component object. Open the “Browser Window” and select the specific component object whose surface attributes you want to choose.

Setting the Base Color

Set the color of the object first. In this case, set it by using Diffuse Color in the “Surface Window.” Maintain the whole balance with rough coloring.

Only Diffuse Color is set for the whole image.Since the same surface attribute applies to the whole image, it looks like a toy. The default surface attribute of Shade resembles plastic with a strong gloss.

Setting the Shading Parameters

Next, set the specular values, brightness, and transparency. Shade can express the surface qualities through a combination of parameters. The program sets many of them in the Basics section, and sets particular surface qualities in the Effects section.

Specular and Reflection are set up separately.Specular on skin and clothes is soft. Specular on coated surfaces like the can and buttons is strong. Setting various surface attributes enables you to move the image away from appearing like a toy.

Setting the Mapping Pattern

Patterns and images with different surface qualities can be applied to each part. This work is called Mapping.

Nine kinds of preset patterns or image files, such as Check and Moody, can be specified using the Mapping pop-up menu in the “Surface Window.”

Mapping is applied to various parts. Bump is applied on the denim and the stitches of the cap.All surface attributes can be found in the folder “Surface materials” on the CD-ROM. Use the Load button (see page 71) to apply these saved surface attributes to individual parts of Paint Boy.
