VRML Coloring Options
Select the type of coloring with which the VRML surface should be colored.
- Shading: Colors the plot with n shades of one color. The base-color is
specified by the amount of red, green and blue it contains; enter these values
in the labeled input fields (range: 0.0-1.0). The number of shades used, n,
can be defined in the Shade Count input field.
- Flat Color: Colors the plot with a single, flat color. The base-color can
be specified in the red, green and blue input fields (range: 0.0-1.0).
- Rainbow: Colors the plot with a rainbow of color, ranging from purple for
the minimum intensities to red for the maximum intensities.
Color Spread, Color Shift and Peak Highlighting are only important/valid when
Rainbow or Shading have been selected.
- Color Spread: Defines the percentage of the intensity range
over which the colors/shades should be spread evenly. By default, the colors
are spread evenly from the minimum intensity to the average intensity; all
points above average are colored with one color. (range: 0.0-1.0)
- 1.0 means spread the colors/shades evenly over the full intensity range.
- 0.5 means spread the colors/shades evenly over half the intensity range.
- Color Shift: Defines the percentage by which the even color
spread should be shifted up or down on the plot surface. (i.e.- 0.5 means
start the even color spread at the minimum intensity value plus half the
intensity range; below that point, all points will be one color/shade.)
- Peak Highlighting: This option is useful for adding contrast
to the surface. When checked, the peaks of the plot will be colored with the
darkest color in the shade or rainbow color-array.
Use the Light Intensity input field to enter the amount of light
to put on the surface; a simple, VRML spotlight-node is used to produce this
light.
