Overview
• 3D Effects
is a master switch, and its settings
of Blur and Depth make a great difference;
you can click the "+" button to unlink them
for independent adjustment.
• 3D Lighting provides a "light source"
without which any depth information in the
effect wouldn't be visible. The lighting
settings let you illuminate your 3D landscape
and vary its reflective properties.
To apply 3D filter effects:
1. Click
Filter Effects on the Attributes toolbar.
2. Check the 3D Effects box at the left. The 3D Lighting box is checked
by default.
3. Adjust the "master control" sliders here to vary the overall properties
of any individual 3D effects you select.
• Blur specifies the amount of smoothing applied. Larger blur sizes
give the impression of broader, more gradual changes in height.
• Depth specifies how steep the changes in depth appear.
• The
button is normally down, which links the two sliders so that
sharp changes in Depth are smoothed out by the Blur parameter. To
adjust the sliders independently, click the button so it's up.
• (Optional) If needed, expand the preview pane by clicking the
Show/Hide Preview button. When expanded, the effects are applied
only in the preview window. While the pane is collapsed (click the
button again), filter effects are applied directly to the object on the
page. The former approach lets you work on your effects in isolation
without other page objects interfering while fine-tuning your effects.
