Defines the properties of rendered surfaces. You can control different components of color as defined by reflectance, emissive, and attenuation properties of the surface of an object.

Diffuse

Displays the amount of light a surface reflects equally in all directions. Unlike ambient light, diffuse light also depends on the direction of the light source. When a point on a surface is perpendicular to a light source, the surface reflects the maximum amount of light. When a point on a surface is parallel to a light source, the surface reflects no color based upon the light. Diffuse color is the color of diffuse light reflection from a light source.

Specular

Displays the specular reflection. Unlike diffuse light reflection, specular reflection fully depends on the direction of the light source. Additionally, specular reflection depends upon surface finish or texture. Specular color is the color of specular reflection for a light source.

Ambient

Displays ambient light for the surface appearance. In some cases, a point on a surface is not illuminated by any light source. You can think of ambient light as a light source that illuminates all points on all surfaces equally. Therefore, ambient light defines a minimum illumination for all surfaces. The ambient color is the diffuse light reflected from the light source.

Emission

Displays the emission light for the surface appearance. Emission originates from the object surfaces, rather than reflecting off the surface from a light source. When you define an emission color, a surface appears to glow.

For guidelines for creating colors and lighting, see Style Command.

Copy From Edges Color

Defines the color either by copying the Diffuse color or by defining it using either the Red, green, blue or Hue, saturation, intensity color bars. In addition to defining the color of 3D curves, this property allows the color of a surface to differ from the color of its boundary curves.

Red, green, blue

Adjusts the amount of red, green, and blue. You can type a value in the box or use the sliders.

Hue, saturation, intensity

Adjusts the amount of color saturation and intensity. You can type a value in the box or use the sliders. The color and hue values must be between 0 and 1.

Shininess

Controls the amount of specular reflection from a light source. If the shininess value is high, the surface displays as a polished piece of metal or an object covered with high-gloss paint. If the shininess value is low, the object appears as a piece of paper or an object covered with flat paint.

Opacity

Controls the degree to which a surface is visible behind an obscuring surface. If a surface has high opacity and high shininess, it has the appearance of glass. If a surface is less shiny, it looks more like plastic.

The Preview options are defined as follows:

Preview render mode

Determines the physical appearance of 3D objects in the workspace. The options available are as follows:

Outline - Displays objects with edges as a single line and the surfaces solid. Edge lines and faces not within the normal view are hidden. This setting provides a fast and simple way to review spacing relationships between objects. Because this view involves hidden lines, the display is less cluttered.

Smooth Shaded - Displays objects in a solid format with smooth shaded surfaces.

Shaded with Enhanced Edges - Displays objects the same as the Smooth Shaded option but with a dark line emphasizing the edges of the objects.
