The Edit Each/All/On's option menu allows one to edit just the current object, all objects at once, or just the objects that are currently turned On. Features that can be edited in tandem for many objects include: point size, line width, material properties, and drawing data type and style. Line color can also be changed in tandem if a separate check box is selected.
The name of each object can be edited using the text edit box.
The numbered check boxes allow one to conveniently turn selected objects on and off. When an object is turned on, it becomes the current object. Only 48 checkboxes will be displayed here; if you have more objects, use the Edit - Object List menu entry to bring up a complete Object List window.
The Draw Data Type option selects which type of data to draw. You can select to draw contour data, mesh data or no data at all.
The Drawing Style option selects the drawing style. You can select between drawing points, lines, filled or filled outline.
To select which parameter group is displayed in the panel in the lower right
part of the window,
use the mouse to select one of the entries in the list box in the lower left.
The controls in each group are listed below.
Line color
Use the Red, Green, and Blue sliders to adjust the
line color of the current object. This also sets the
fill color unless a separate color is selected in the Fill Color panel.
The Transparency slider selects object
transparency. Transparency is only an approximation and can
easily generate artifacts. To minimize these artifacts, the back
face of the object will not be displayed unless the
Light Both Sides button is selected in the
Material panel. Try it both ways to see which looks best.
By default, color changes will be applied to only one object in one
model. Check Change multiple objects to modify more than one object
at a time. The setting of the Edit combo box and the Edit
radio buttons in the Model Edit window will then control which objects
are changed together with the current object.
Fill color
Use the sliders to adjust the fill color of the current object.
Select Use fill color to have this color used instead of the line
color whenever the object is being displayed as filled. Select
Use for spheres to have the fill color used just for display of
spheres. This would allow you to have a surface of one color studded with
spheres of another color at selected points.
Material
The Ambient slider adjusts ambient, or non-directional, light
hitting the object.
The Diffuse slider adjusts light hitting the object from the
light source, which then diffuses in a direction-dependent way.
The Shininess and Specularity sliders together adjust the
shininess or highlights of the object.
Select Light Both Sides to have the object
lit on both its outside and inside surfaces. If you just want to have the
inside surface show up less dark than it does by default, try increasing the
Ambient value and decreasing the Diffuse value to compensate.
Points
This panel controls the rendering of spheres that are displayed at individual
points. The sphere radius can be incremented, decremented, or typed
into the spin box. Note that setting the radius non-zero will cause
points to be displayed at each point, even for open and closed contour
objects. The quality of the spheres is controlled by the
two quality spin boxes, one to set the quality for the particular
object, and one to set the overall minimum quality for all objects.
The display quality for an object is the maximum of its own
quality setting and the global setting (range 1 - 4). The global
setting can also be controlled by the g and G hot keys.
Lines
The 2D Line Width slider changes the line width used when drawing the
model in image display windows in 3dmod. The 3D Line Width slider
changes the line width used to draw
draw the objects in the model view window.
The Anti-alias rendering check box
selects anti-alias rendering for lines.
Lines will look smoother with this option on; however,
some artifacts may be noticed. The Thicken current contour check
box can be used to highlight the current contour by drawing it thicker
than other contours. This will
have an effect only for objects whose drawing style is Lines.
This feature is most useful when using the third mouse button to select
contours.
Values
This panel controls the display of values that have been stored in the
model in one of two ways. Some programs will now store values for
each contour or point using the fine-grained storage capabilities.
The sda program stored surface density values in the mesh as the
magnitude of the surface normals. The radio buttons at the top allow
you to select whether to Show stored values or to
Show normal magnitudes.
The Black and White sliders adjust the contrast range of the displayed values, and False color will display the values in false color rather than as an intensity modulation of the object's color. The intensity ramp can be inverted by setting the Black slider higher than the White one. The Turn off Low and High buttons can be used to turn off the drawing of contours or points whose stored values fall below the lower of the Black and White levels or above the higher of the two levels, respectively. This feature does not work for mesh displays.
Note that once the drawing of stored values is turned on, it is applied
to model features drawn in the image display windows, if any.
Clip
These controls allow you to set up clipping planes for an
individual
object as well as global clipping planes that will be applied to all
objects. The position and orientation of a plane is adjusted by
holding down the Ctrl key and doing the same operations that would
ordinarily move the model.
Use the Object and Global radio buttons to select whether to adjust global planes or planes for the current object. If you want the current object to be clipped only by its own planes and not by any global planes, turn on Skip global planes. The spin box allows you to select the current plane, the one that is adjusted by the remaining controls. Use Clipping plane ON to toggle the current clipping plane on or off.
The Reset button moves the plane back to its default location and orientation through the middle of the object or model. The Invert button inverts the direction of the clipping plane. Turn on Adjust all planes to operate on all of the object or global planes at once; these operations include moving, rotating, and turning on or off. This option is useful if you have set up several planes to enclose a box and want to shift or rotate the box as a unit.
Once the current plane is turned on, hold down the Ctrl key to move and rotate the plane instead of the model. Use the left mouse button or the arrow keys to move the plane, and the middle mouse button or the keypad keys to rotate the plane.
Up to 6 clipping planes may be defined for each object, as well as 6
global planes. However, the OpenGL implementation on your machine
limits the total number of planes that can be applied to an object.
There are guaranteed to be at least 6 but probably are only 6. If this
limit comes into play, object planes count first toward the limit.
Move
This panel allows one to view orthogonal faces of the model.
Each column of buttons will move by 90 degree rotations about
one of the three axes.
The Center on Object button will center the display on the
current object.
Subsets
This panel allows one to view the current object, surface or
contour of the model, if one is selected. Current Surface
Only or Current Contour Only will show only the current
surface or contour in the current object. Surface & Other
Objects or Contour & Other Objects will show the current
surface or contour in the current object, plus all other objects
that are turned on.
Meshing
This panel allows the current object to be meshed if it is an open or closed
object. The various controls correspond to options in
Imodmesh; see that man page
for more details. If the object has been meshed before, the
parameters for that meshing will be used to set these controls. In addition,
any parameters set through Imodmesh but not appearing here, such as X or Y
limits or lists of Z values to not cap to, will still be
applied when remeshing through this interface. The controls are:
