The Appearance Menu
Appearance | Style
Appearance | Materials
Choosing "Appearance | Appearance" from the iSight menu opens the Appearance panel.
The Top button bar chooses the appearance mode, with buttons "1 2 3 4 B V". By default, these map to the following appearance attributes:
The Model options menu chooses the way in which the surface color is mapped. If you choose "Gaussian curvature" from the "Appearance | Color" panel, "Ambient and diffuse", for example means that the color by Gaussian curvature is interpreted as ambient and diffuse light.
