Transparency
The Transparency subnode () adds transparency to 3D plots and to most 2D plots that use a Height Expression subnode. Add it to make the plot more or less transparent. In the Model Builder, right-click a plot node and select Transparency.
Transparency
From the Input list, choose Constant to specify a constant transparency for the whole plot or Expression to use an expression to control the transparency for each vertex in the mesh individually.
If Constant is selected from the Input list, in the Transparency field, or using the slider underneath, specify the transparency as a value between 0 (no transparency) and 1 (fully transparent).
If Expression is selected from the Input list, use the settings below to control the transparency:
•
Click the Replace Expression () button to select an expression for defining the transparency or enter an expression in the Expression field.
•
Select a Unit from the list. You can select from a predefined number of applicable units or enter any compatible unit in the text field.
•
From the Mapping list, choose Auto (the default) or Explicit. Select Auto to map the values of the expression to a transparency range, where 0 corresponds to no transparency and 1 corresponds to complete transparency. Select Explicit to use the values of the expression directly as transparency. When Auto is selected, you can control the mapping with these settings:
-
In the Minimum value field, specify a value between 0 (no transparency) and 1 (fully transparent) to map the minimum value of the expression to. The default is 0.
-
In the Maximum value field, specify a value between 0 (no transparency) and 1 (fully transparent) to map the maximum value of the expression to. The default is 1.
-
From the Scale list, choose Linear (the default) or Logarithmic.
-
Select the Reverse checkbox to reverse the mapping of the transparency; that is, the maximum value of the expression is mapped to the minimum value of the transparency range.
-
Select the Manual value range checkbox to replace the values in the Minimum and Maximum fields if desired.
In the Fresnel transmittance field, or using the slider underneath, specify the Fresnel transmittance as a value between 0 (no transmittance) and 1 (full transmittance). Fresnel transmittance results in that the transparency depends on the angle of incidence, which can improve realism.
