WMS:Lighting Options

The Lighting Options option in the Display Options dialog can be used to set the light and shading of the image in the Graphics Window. When the Use light source option is selected, the image is shaded according to the intensity and lighting angle. When the Smooth features option is selected, the shading is smoothed. The image shows an example of a watershed that has color filled contours and the lighting and shading options applied. The default display mode for a TIN or 2D Grids in the Graphics Window is a wire-frame image. Color shading and hidden surface removal can be applied to either TINs or 2D Grids in order to generate a realistic image. Hill shaded images of DEMs can also be created with a DEM present. Images can be "draped" over a TIN if properly registered. This is controlled in the Image Display Options (found as a button on the Map tab in the Display Options dialog) by choosing to map the image to the TIN. If an image is mapped it will be draped and shaded over the TIN when using Lighting Options. Related Topics: Display Options Contour Options Lighting Angle
