Colorize face properties

Colorize various properties of a surface consisting of 3d faces.

Access methods

8 Toolbar: Colorize_32x32.png

8 Menu: ComputationalCAD † Colorize faces

7 Command entry: CC:FACES:COLORIZE

Dialog

Select faces:
Select the 3dfaces defining the surface.

Specify target property [ARea/Center Z/minimum ANgle/MINimumZ/MAXimumZ] <ARea>:
Specify the property to colorize. Default is <ARea>.

Specify number of colors <6>:
Specify the number of colors to use Expects an integer between 2 and 32768. Default is <6>.

Specify lower cutoff percentage <0>:
Specify the the lower cutoff percentage. Default is <0>.

Specify upper cutoff percentage <100>:
Specify the the upper cutoff percentage. Default is <100>.

Note

The faces will be colorized in the order blue – cyan – green – yellow – red – magenta where the blue color value is assigned to the face(s) with the smallest selected target property value and the magenta color value is assigned to the face(s) with the highest selected target property value. The cutoff percentages allow specifying the color of the minimum and maximum target property values as shown in the first example.

The center Z, minimum Z and maximum Z target properties are best applicable to a terrain surface.

The minimum Angle property allows visualizing the triangulation quality.

The area property visualizes areas with high “density” of the faces defining a surface (densit plot).

 

Example

In below figure, following color schemes have been applied:

a)  6 colors, from 0% to 100%

b)  6 colors, from 0% to 100%, colors reversed

c)  100 colors, from 0% to 100%

d)  100 colors, from 20% to 80% (i.e. all values smaller than 20% of the value range are colored blue and all values greater than 80% of the value range are colored magenta)

e)  100 colors, from -20% to 140%. Specifying negative values for the lower cutoff value and values greater than 100% for the upper cutoff value, respectively, influences the colors for the minimum and maximum target property, respectively.
