Shading a Surface
To produce a shaded surface in the WzSurface Tool, you can specify a shading algorithm, or you can drape an image over a surface to produce shading effects.
Specifying a Shading Algorithm
The following algorithms can be used to shade surface data: None (no shading), Gouraud, Elevation, and From Variable.
To specify a shading algorithm, follow these steps:
1. Choose Attributes=>Surface Attributes to bring up the Surface Attributes dialog box.
2. Click MB1 on the Shading list button and drag to select the algorithm you prefer.
3. Click OK or Apply in the Surface Attributes dialog box to apply the shading to the surface.
Specifying a Shade Variable
A shade variable is the name of the variable that contains the shading information.
To specify a shade variable, follow these steps:
1. Choose Attributes=>Surface Attributes to bring up the Surface Attributes dialog box.
2. Click MB1 on the Shading list button and select the From Variable function.
3. Click MB1 in the Shade Variable text field, then type the name of the shade variable you want to use.
4. Click OK or Apply in the Surface Attributes dialog box to apply the shading to the surface.
