Over the years I have worked out various convoluted ways of creating a depth image of our eyeTricks 3D Stereograms logo mostly using a blend clipped inside a shape and other methods. All of which were less than perfect.
But this is the simplest and most effective solution that uses an Art Brush and a continuous path shown in blue in the Reveal image. The brush is a simple rectangle with a white to 80% black linear fill with a black and white shape on top to make the brush rounded. These two shapes where made into a bitmap (the art brush does not support Multiply transparency) and the bitmap made into a brush.
The line was changed to 72px wide then the brush applied to create the smooth blending.
The iris part of the eye is a gradient filled vector shape.
Eternal gratitude to Acorn for suggesting this Art Brush solution years ago.
