The DISPLAY OPTIONS window displays the current part and contains the
following commonly used functions, shown in Figure
1.10.1.
Figure 1.10.1 Display Options
1.
SHADE (toggle)
This command displays the elements as if they were illuminated by a light
source. Elements that are not directly exposed to the light source are
appropriately “shaded” to simulate the actual shading effect.
Eta/Post uses two methods for object shading: flat and smooth. Flat
shading shades each polygon upon the intensity of the light over a series of
polygons making the elements appear flat and angled.
2.
SMOOTH SHADE (toggle)
This function uses the Gourmand shading method to make the model appear
more smoothly. It interpolates shade across edges and reduces effect of the intensity
change. The feature angles between adjacent elements are smoothed by this
shading method.
NOTE: The SMOOTH SHADE option is only available when the SHADE option is on.
3.
MATERIAL COLOR (toggle)
If this function is toggled on, the model will be displayed in material
color. This function can only be used in SHADE mode.
4.
FILL COLOR (toggle)
This function toggles on/off FILL COLOR mode of the model. FILL COLOR
fills the displayed elements with their designated part color.
5.
ELEMENT EDGE (toggle)
This function can only be used in FILL COLOR mode. The outline of the
elements is plotted in white when the option is toggled on. The model can be
displayed without the outline by toggling off the option.
NOTE: The ELEMENT EDGE is only available when the FILL COLOR or SHADE option is on.
6. SHRINK (toggle)
SHRINK creates a plot with elements reduced in size by 20 percent. This
option allows the user to toggle the function on/off.
7. HIDDEN SURFACE
(toggle)
This function toggles on/off the model in HIDDEN SURFACE mode. HIDDEN
SURFACE hides the elements behind the elements viewed from the user’s point of
view.
8. PLATE NORMAL
(toggle)
This function toggles plate normal on and off. The plate normal is
shown with a vector drawn at the center of the element, and along the element’s
normal direction.
9. BACKGROUND
(toggle)
If this function is toggled on, the background color is set to faded
color (default). Otherwise, the default background color is black. The user may
open the Background Color menu in EDIT menu to adjust background color.
