Isolinies / Isotherms (control panel)
The control panel Isolines is used to adjust parameters of isoline evaluations (isotherms, in the case of temperature is chosen for the active evaluation function).
Isolines are shown colorized. Actual colorizing follows values of currently active function (temperature, heat flux, surface humidity etc. - selected within General control panel) and currently selected Colour table.
The isolines (or isotherms) are drawn on component's surface or on slice planes, and are therefore only visible if these evaluations are active also. Settings chosen within control panels Slice X, Slice Y, Slice Z and Surface have thereafter an impact onto evaluation of isolines.
Which isolines are shown can be selectively chosen by setting the number of intervals (#Interv.) or by choosing the step value. Isolines will be created only for values within the interval Min and Max according to the input therein.
At initial view of isotherms the interval of 1°C, starting at 0°C is set and isolines shown.
Isolines can be labelled accordingly also and/or emphasized bolded (as a tube).
| Active, Opaque, Colorize | Decide about the visibility, colorizing and transparency of the lines shown |
| Min/Max | The values of Maximum and Minimum, shown at the top and bottom of the panel, display the current extent of selected evaluation function. This interval can be reduced by the input in the respective fields. The input can be performed either by the entry of numeric values into the respective input field or by moving the sliders between the extent values. |
| #interv. | Number of equidistant intervals dividing the extent between the input Min and Max values. The step will be calculated from these values. |
| Step | The value interval at which isolines shall be drawn. |
| Start at | The start value fro which (in both directions, towards Min and towards Max) the values of isolines to be drawn shall be calculated. |
| Bold n-th | Selected isolines (each N-th) will be shown emphasized (Bold n-th) - as a thick tube instead of a thin line. Isoline labels are shown only on bolded lines if the option "Bold n-th" is chosen. Remark: The tube itself if always partially transparent to allow proper display of isoline labels (visibility test) |
| Tube Radius | Emphasized isolines (switched on by "Bold n-th") are shown as a tube to better emphasize respective isolines (compared to single pixel thick line). The radius is entered in units of the coordinate system - i.e. millimetres. Setting the tube radius = 0 will show it as simple line. Remark: The number of sides rendered for the tube can be adjusted within application settings. |
Remark: It is advisable to adjust the surface "holding" the isolines (i.e. Surface or Slices) by showing it transparent or opaque.
Alternatively adjust colorizing of isolines or the surface "holding" them to dark or bright to receive the required contrast of the image.
Remark: Because slice planes, holding isolines, intersect with model's interior only it is advisable to either turn the view of the surface completely off or show it partially transparent (i.e. not opaque) or show it as wireframe only.
Remark: Isolines are lines shown and colorized by the constant value of the primary function chosen (Isotherms, lines of equal heat flux, lines of equal surface humidity, and so on). Isolines are displayed on construction's surface (Surface) and on slice planes (SliceX,Y,Z) (only if these are active). To show isolines only, without the surface "holding" them, turn that surface completely transparent (set opacity = 0). The selection of values at which isolines are shown is givien by the definition of a start value (Start at) and of a interval length (Step) (or number of intervals).
Remark: The visibility of isolines is directly dependant on the visibility of the surface object holding it:
→ Isolines on the component's surface are only visible if the Surface is also active. To get better view onto isolines turn the surface transparent – Surface→Opacity=0.0;
→ Isolines on slices (X/Y/Z) are only shown if the respective slice is also active. To get better view onto isolines turn the respective slice transparent – SliceX/Y/Z→Opacity=0.0
