Chapter 39. 3D LINGO > SHADERS AND TEXTURES

SHADERS AND TEXTURES

You can use Lingo to change the appearance of a surface in a 3D world. You do this by creating or changing shaders. A shader is what defines what a surface looks like. It can be a simple definition, like a color, or a complex one like a bitmap image.

Figure 39.5 shows a 3D world created in a 3D graphics program. The walls use a bitmap texture and there is a bitmap displayed on the television set and as a window. The floor has a repeating bitmap as well. The chair and table, however, have a simple color as a shader.
