The Make Fractal Pattern command is a pattern generator that creates interesting landscapes. These topographic patterns can be filled with color, or even embossed using a paper texture.
When you create fractal patterns, the following options allow you to fine-tune your creation:
• Size sets the exact size of the tile you are creating. If your computer has a lot of memory, you can make a large file with a high resolution. Depending on how much memory your computer has available to Corel Painter, some of the size options may not be available.
• Power controls the intricacy of the pattern's definition, as if you were "zooming" in and out on a textured surface with a microscope. Move the Power slider to the right to zoom out and see many small patterns. Move the Power slider to the left to zoom in and see fewer large patterns.
Feature Size defines the number of prominent features within the tile. Moving the slider to the left increases the number of repetitions per tile.
The Feature Size slider determines the number of repetitions per tile. Left=90%, Right=20%.
Softness adjusts the edge softness of the pattern.
Angle changes the direction from which you view the fractal.
• Thinness emphasizes the direction suggested by the lines of the fractal pattern. Thinner lines produce a more linear look.
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 different ways.
• Height as Luminance displays pseudo-height information as luminance. White areas are represented as peaks, and dark areas become depressions. Images generated with this option can be used with the Apply Surface Texture effect.
• 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.
You can also turn a fractal pattern into a paper texture that will be saved to the Paper library.
