Edit Miscellaneous Properties Help
This widget lets you change some miscellaneous properties.
Currently this does not work. Eventually it will let you change
the z magnification (z spacing) interactively instead of
only on the command line (-z option).
When an object is displayed in wireframe mode, usually every
wireframe contour is displayed. If this is set to 2, then every other
wireframe contour is displayed. A setting of 3 means display every
third contour, etc. This is useful if the display is too cluttered
with contour lines. This can also be done on the command line with
the -g option.
Wire Cross-Hatch Increment
In addition to displaying contour lines, you can also
display lines "along the length" of the objects (i.e., perpendicular
to the contour lines). Thus the object surface appears to be
cross-hatched. This option lets you control how many of these
lines you see (in the same manner as the Wire Increment specification).
Pressing the H key (capital H) when the cursor is in the main
display window turns the cross-hatch mode on and off.
Cross hatches will look very strange unless there are the same
number points in each contour. By default, DAVE resamples each
contour specified in a pts file to have the same number of points
(see the -n command line option).
This option controls which data volume z planes are displayed.
The specification is the same as for Wire Increment. This option
only works (I think) when you are displaying data volumes in planes
mode and by z planes. Normally, when in planes mode, DAVE picks
which planes it shows (x,y, or z planes) depending upon orientation.
You should lock DAVE into zplane mode before using this option.
This is done by selecting the Volume Debugging widget from the
menu in the Edit Volume widget. Then click on the Z button and
the Override button. Note: setting the plane increment to something
other than 1 before you have done this may crash the system.
Line Width of Wireframe
This lets you specify the width of all of the wireframe
lines (and boxes) in the display window. Alternatively, pressing
the L key when the cursor is in the display window will toggle through
a bunch of line thicknesses. This makes the lines seem a little
brighter. Thicker lines may also be easier to see if you take
a picture (a slide or a print) or if you are using stereo glasses
which tend to cut out some light.
This sets the number of degrees that the image will rotate with
each update. It is simply a more precise way of setting the
rotation angle than by clicking on the rotation angle slider in the
DAVE Master widget. Setting a precise angle is particularly important
if you want to make a movie and you want to rotate (in small steps)
precisely 360 degrees. In that circumstance you need to specify a
rotation angle which is an exact divisor of 360.
Note: this entry does not change when the rotation angle is modified
by clicking on the rotation angle slider. Also, its entry is not
sent to DAVE unless a new number (which may be the same as the previous
number) has been entered. Thus just pressing "return" will not
resend the current entry. It must be re-entered.
