The None face style produces no shading, and displays only edges. Customize
edge settings to control whether facet edges or isolines are displayed.
Lighting Quality
Lighting quality determines the smoothness of shaded objects.
Faceted lighting computes a single color for each face. Individual faces appear
flat. Smooth lighting smoothes the edges between polygon faces by computing
the colors as a gradient between the faces’ vertices. This gives objects a smooth
appearance.
For the Smoothest option, the Per-Pixel Lighting setting must be enabled
under the Hardware acceleration option of -3DCONFIG. The colors are
computed for individual pixels, giving a smoother appearance. If not, the
Smooth setting is used instead.
Highlights
The size of an object’ s highlights affect the perception of shininess. A smaller,
more intense highlight makes objects appear shinier. The highlight intensity
that is set in a visual style does not apply to objects with attached materials.
