Using Depth Cues in 3D Models

Rendering

Select a foreground from the browser. Once you have selected a foreground, it is displayed in the tree. If you have already added a foreground to the model, a new selection will replace the old foreground.

  1. Select the perspective viewing angle for the model.
  2. On the tab, in the Environment group, select Foreground/Fog.
  3. Select the General folder in Vertex Library.
  4. Double-click the Depth Cue icon in the browser.
  5. Visualize the view by pressing Shift+P to preview the depth cue.
    • If the model is entirely covered in fog, the distance between the fog and the viewing point is too small.
    • If all of the fog is far beyond the model, the distance is probably too large.
  6. Select the foreground from the tree, and then select the context-sensitive function Edit Values.

    The Foreground Editing dialog box opens.

  7. Click the Near depth cue parameter.
    • Enter a suitable distance from the viewing point to the fog starting plane in the Properties field in millimeters.
    • Click the Set button.
  8. Click the Far depth cue parameter.
    • Enter a suitable distance from the viewing point to the plane of completely opaque fog in the Properties field in millimeters.
    • Click the Set button.
  9. Click the Background Color depth cue parameter.
    • Click the Browse button, and select a color for the fog in the window.
    • Click the Set button.
  10. Select OK.
  11. Visualize the view by pressing Shift+P.
Note:
  • The browser shows the My Library (user's foregrounds) and Vertex Library (software supplier's foregrounds).
  • You can delete a foreground from a model by selecting the Foreground symbol from the tree and then selecting the context-sensitive function Delete.
