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.
4. Check a 3D effect in the 3D Effects list which reflects the 3D effect
you can achieve.
