Labels (control panel)
The
control panel Labels contains settings for labelling of
Isolines
and of the Colorbar
Labels of Isolines are placed over Isolines shown
over the
slice planes X/Y/Z or over
component's surface.
Show labels |
Turns labelling of isolines on or off
|
Distance along line |
The distance between labelling points along each isoline (staring
at the middle of each polyline of each isoline)
The initial value of the distance value is calculated based on the median
extent of the component modelled (1/3 of it). |
Proximity |
The minimum distance between any two labelling points.
|
Font size [pts] |
Size of letters used for labels.
The actual size scales with the height of the 3d view. |
Decimal digits |
Number of decimal digits after decimal comma to show on
isoline labels. |
Remark: In general it is advisable to keep the distance along line
at 1/3 of the component's extent. The proximity is commonly changed
together with the font size. Generally the Proximity is always
smaller then Distance along line.
Remark: Visibility of each separate label is checked against all opaque
surfaces and objects within the view. Transparent surfaces and do not obscure
labels.
Remark: Labels of isolines shown with
active isoline option "Bold n-th" are
shown on emphasized isolines only.
The tricky algorithm positioning the labels can be described as follows:
- Each isoline is represented by a polyline - under certain circumstances
there will be many polylines for the same isoline value generated (sections of
isolines).
- The initial labelling point is set at the middle of such polyline (very
short polylines are skipped).
- Starting from that initial point, in both directions of the polyline,
further points will be placed - repeatedly at each
distance along line.
- After all points are set for all polylines the distance of each pair of
points is tested against proximity - one of the points is removed if
the distance is less then the set proximity value. This avoids overlapping of
labels placed too nearly (below the value of proximity) to each other.
- All labelling points are tested for their visibility - this highly depends
on the orientation of the 3d view. Points obscured by opaque surfaces are
removed.
- All points still on the list are used to place labels in requested font
size. The size and orientation of labels is independent of the current 3d
transformation.
Value labels of the
colorbar are placed at one side of the coloured
bar.
Remark: When Results3D is showing a periodic evaluation at some time point, the title of the colour bar will
display that value.
