RegionBoundaryStyle
is an option for plotting functions that specifies the boundary style for the region over which the plot is being drawn.
Details

- RegionBoundaryStyle is typically used for plots that contain discrete elements, to better show the full region of the plot.
- The region being styled may come from a variable specification, RegionFunction or a combination of sources.
- The following settings can be used:
-
Automatic automatically style the region boundary None omit the region boundary style draw with specified graphics directives - With RegionBoundaryStyle->Automatic, regions that completely fill the plot will generally not be drawn.

Automatically style the plotted region:
Omit the boundary of the region:
Automatic will style the region in ContourPlot3D:
Scope (5)
Use a black boundary for the region:
Style the region from a region function:
By default, the boundary is not shown for full regions:
Specify an explicit boundary style:
Use explicit RegionBoundaryStyle in ContourPlot3D:
