658 Corel Painter X3 Getting Started Guide
A section of an image with Glass Distortion applied.
To create a Glass Distortion dynamic layer
1 Do one of the following:
• In the Layers panel, choose the Canvas.
• Choose a selection tool from the toolbox, and then drag in the document window
to select an area.
2 In the Layers panel, click the Dynamic Plug-ins button , and choose Glass
Distortion.
3 In the Glass Distortion Options dialog box, choose one of the following
displacement sources from the Using list box:
• Paper — uses the selected paper texture. Paper texture is good for creating the
pebbled glass effect. Unless you want frosted glass, you’ll probably want to
increase the scale of the paper.
• Current Selection — uses the currently selected area in the document window
• Image Luminance — uses the current document’s luminance
• Original Luminance — uses the clone source’s luminance
Image pixels are displaced, based on the light and dark areas of the source.
4 To modify the distortion effect, adjust any of the following sliders:
• Softness — controls the transitions between displaced colors. Increasing softness
creates more intermediate steps and produces a smoother distortion. If you
experience aliasing in a glass distortion, try increasing the softness.
• Amount — controls the degree of displacement. A higher amount leads to more
distortion.
• Variance — creates multiple variations in the neighborhood of the displacement.
The result of increasing variance depends on the type of image and other settings.
