Copyright Goodheart-Willcox Co., Inc. 470 AutoCAD and Its Applications—Advanced The properties in the Transforms and Position categories are the same as described for a marble map. Refer to the Marble section for details on these properties. Speckle A speckle map is a 3D map based on a random pattern of dots created from two colors. This map is very useful for textured walls, sand, granite, and so on. When you specify Speckle as the map for a property, the texture editor displays the properties for the map, Figure 17-32. The settings for a speckle map are very simple. In the Appearance category, pick colors for the Color 1 and Color 2 properties. You cannot use maps, only colors. To swap the color defi nitions, pick the button next to the properties and select Swap Colors from the drop-down list. The Size property controls the size of the speckles. The properties in the Transforms and Position categories are the same as described for a marble map. Refer to the Marble section for details on these properties. Waves A waves map is a 3D map in a pattern of concentric circles. Imagine dropping two or three stones into a pool of water and watching the ripples intersect with each other. A number of wave centers are randomly generated and a pattern created by the overlapping waves is the result. As the name implies, the waves map is usually used to simulate water. When you specify Waves as the map for a property, the texture editor displays the properties for the map, Figure 17-33. In the Appearance category, pick colors for the Color 1 and Color 2 properties. You cannot use maps, only colors. To swap the color defi nitions, pick the button next to the properties and select Swap Colors from the drop-down list. The Distribution property can be set to 2D or 3D. This setting determines how the wave centers are distributed on the object. Selecting 3D means that the wave centers are randomly distributed over the surface of an imaginary sphere. This distribution affects all sides of an object. On the other hand, selecting 2D means that the wave centers are distributed on the XY plane. This is much better for nearly fl at surfaces, such as the surface of a pond or lake.
