14.7 Isosurface plot
An isosurface plot draws a surface through all the points of the model that have the same value. An isosurface plot can be added by selecting the Post/Isosurface plot from the menu. A new item will appear in the Model Viewer that the user can select to edit the surface plot's properties. The following properties are defined.
- Data field - selects the data field that will be used to calculate the isosurfaces.
- Allow clipping: If yes, iso-surfaces will be clipped by any active plane cuts.
- Gradient - sets the color gradient that will be used to color the isosurfaces.
- Slices - defines the number of isosurfaces to draw.
- Show legend - shows a legend bar for the isosurface plot.
- Smooth - when selected yes, the surfaces will be drawn using smooth shading. When selected no, the isosurfaces are drawn with flat shading. Note that when using smooth shading, additional calculations need to be performed which may slow down the rendering of the plot.
The isosurface plot is enabled by selecting the enable button on the Model Viewer panel. Similarly, disabling the plot can be done by pressing the same button again. You can delete the isosurface plot by pressing the delete button on the Model Viewer panel.
Since the isosurface plot is drawn inside the model, it is advisable to hide it. You can hide the model by hiding each individual material, or by clicking the enable button when the model is selected in the Model Viewer.
