- Surface Color: The surface color of an object in Red, Green, and Blue
- intensities. The range of each color is 0.0 to 1.0. A
- value of 0.0 means that there is no color and 1.0 means
- there is the maximum amount of the color.
-
- Red: This is the red color intensity of the surface.
- Green: This is the green color intensity of the surface.
- Blue: This is the blue color intensity of the surface.
-
- Surface Properties: This is the physical properties of the objects surface.
-
- Ambient Lighting: The intensity of light reflected from the
- object. This is a generic way of simulating
- ambient light. (Ambient light is light that is
- everywhere in the scene it doesn't come from any
- light source objects. don't mistake this property
- for diffuse lighting.) A value of 0.0 means that
- the ambient light is to dim to see. A value of
- 1.0 means the object is saturated by ambient
- light.
-
- Diffuse Lighting: The intensity of light reflected from the object,
- this light comes directly from all light source
- objects. A Value of 1.0 is full intensity. A
- value of 0.0 no diffuse light is reflected. NOTE:
- specifying a diffuse value will not light the
- surface alone you need a light source object
- that has an unobstructed path to the object.
-
- Specular Highlights: This is the intensity of specular highlights.
- A specular highlight is a bright patch of
- light that is the color of the light being
- reflected. The rougher the surface the smaller
- the specular highlight will be. Note specular
- highlights are very directional. A value of
- 1.0 means that the specular highlight will
- be very bright, A value of 0.0 means no
- specular highlights will appear at all.
-
- Reflection: This is the reflectiveness of an object. A value of
- 0.0 means no reflections will appear on the object.
- A value of 1.0 means the object is totally reflective.
-
- Roughness: This is the roughness of the surface. A value of 1.0
- means totally smooth. A value greater than 1.0 means
- the object is rough the grater the value the greater
- the roughness.
-
- Brilliance: This is how brilliant the surface is. This value
- causes the diffuse light to form tighter color bands.
- A value of 1.0 produces large color bands. A value
- grater than 1.0 decreases the color bands. Try tracing
- two objects of the same color side by side and give
- one object a brilliance of 1.0 and the other a
- brilliance of 5.0. Then you will understand exactly
- what brilliance does.
-
- Surface Name: The name of the surface color and attributes.
- Add to Surface list: This will add the color to the surface list.
- After pressing the OK button this will store
- the surface attributes in the current surface
- file. If there is a surface that has the same
- name. A dialog will ask you if you want to
- replace the surface with the new surface you
- just defined.
-
- Surface List: This lists the surfaces stored in the surface file.
- Double clicking on a item in the surface list. Will
- set the surface color, properties, and name to the
- item you double clicked on.
-
- OK Button: Accept the color, surface properties, name, and if the add to
- surface list checkbox is checked it will store the new surface.
-
- Cancel: Cancel changes and if the add to surface list box is checked it,
- will not add the surface to the surface file.
