The Water Refraction Effect creates a pattern resembling light refracting through water.|
The Water Refraction Effect ignores Color 1 and Color 2 and provides its own color for the water, which you can adjust.
The Water Refraction Effect is time sensitive and can use a Clock or Clock Modifier (available in the Water Refraction Options) to modify the Effect over time.
If you enable the Fit To Brush Option you will paint with the Water Refraction Effect sized to your brush.
The Water Refraction Effect has the following Options Pane:|
|Clock:||This Effect can change over time. This control lets you select which of the four Clocks to use (Clocks are assigned in the Brush Pane). Any Green Colored Clock is the one currently in use. Tap the reset button and a Pop Up will appear that lets you reset any of the four Clocks to their initial value. Yellow colored clocks are not in use. Note that you can turn Clocks off by tapping a Green Clock turning all of them yellow.|
|Clock Modifier:||This value is added to the current Clock. You can use this to change where in time this Effect is, relative to the Clock (this allows different Effects to use the same Clock with different offsets).|
|Water Color:||This is the color that will be used for the basic water color. Tap the color to change it. Note that because the refraction is added to the base color, darker base colors work better than lighter colors.|
|Scale:||This value controls the size (zoom or scale) of the refraction Effect. Values closer to zero zoom in. Values farther from zero zoom out.|
|X Offset:||This value controls the position of the refraction pattern in the X (horizontal) direction.|
|Y Offset:||This value controls the position of the refraction pattern in the Y (vertical) direction.|
|Refraction:||This value controls the amount of refraction in the water. Values nearer to zero have less refraction. Values farther from zero have more refraction.|
|Fit To Brush:||If set to a Red X the Effect spans the screen such that as you paint you reveal the Effect. When set to a Green Check Mark the Effect is sized to the brush such that as you paint the entire Effect is within the brush itself.|
|Output Color 1:||By default this is set to REPLACE which means that the set color will be output to Color 1. You can change this as explained in Options Pane Color Mixers.|
|Output Color 2:||By default this is set to IGNORE which means that the Color 2 will be ignored (the original Color 2 will be kept). You can change this as explained in Options Pane Color Mixers.|
The following image shows the Water Refraction Effect with its default settings:|
In this next image, we have set the Scale to 3.0 to produce far less refraction Effect:
The next image shows the Scale set to the maximum. Note how the pattern is more regular and repeats. The large white disturbance in the lower right corner is part of the algorithm that makes the refraction. If it is undesirable, use the X and Y Offset to move the pattern:
In this next image we use the default values but set the Refraction to 1:
And finally we have the Refraction set to the maximum:
