Using Textures, Patterns, and Weaves72
Low Thinness settings show the fractal as
streaks. Use the Angle slider to change the
direction of streaking.
Corel Painter uses four channels to
store graphic information: Red,
Green, Blue, and Alpha.
You can place information other than
color values in these channels.
Channel options allow you to
visualize this information in new and
different ways.
• Height as Luminance displays
pseudo-height information as
luminance. Images generated with
this option are useful in
conjunction with the Apply
Surface Texture effect. White areas
are represented as peaks, and dark
areas become depressions.
• Gradient Bearing uses the Red
channel to display the bearing of
the down angle of a height field.
• Surface Normal uses the Green
and Blue channels to represent the
X and Y components of the surface
normal (angle perpendicular to the
surface at a given point) of the
height field (Green=X, Blue=Y).
These two latter options for viewing a
fractal texture are offered for purely
aesthetic reasons. One way to take
advantage of them is to create color
variations of the texture with the
Adjust Colors feature.
To create fractal patterns:
1 On the Patterns palette, click the
palette menu arrow and choose
Make Fractal Pattern.
2 In the Make Fractal Pattern dialog
box, adjust the fractal options.
Changes you make appear in the
Preview window.
3 When you are satisfied with your
selections, click OK.
Give Corel Painter a little time to
create your new pattern file. When
Corel Painter is finished, your
pattern file is displayed in its own
document window.
Tips
•
To colorize a fractal pattern, choose an
appropriate gradient and use the Express
in Image feature.
•
You can also create interesting patterns
by choosing a colorful gradient and using
the Express in Image command on the
Gradients palette.
Using Weaves
The Weaves palette is, in effect, a
virtual loom that you can use to create
weaves to use as fill patterns.
Libraries of weaves are included with
Corel Painter. You can modify a weave
by changing the way it displays the
scaling and thickness of its threads, or
its color. You can also create and save
weaves of your own. You can preview
your changes before you apply them.
