3D Pattern Map
The 3D Pattern Map effect creates the impression of a textured surface by
applying a mathematical function you select to introduce colour variations.
You can use 3D Pattern Map in conjunction with one or more other 3D filter
effects. (See the
overview above for background and technical details on these
effects.)
2D Pattern Map
The 2D Pattern Map effect creates the impression of a textured surface by
applying a greyscale bitmap you select to introduce colour variations. You can
use 2D Pattern Map in conjunction with one or more other 3D filter effects.
Transparency
The uniform transparency of an object (with 3D filter effects applied) can be
controlled via the Transparency tab (see first example below). However, for
more sophisticated transparency control, especially for simulating reflective
lighting effects on glass objects, transparency settings can instead be set within
the 3D filter effects dialog (check the Transparency option). Transparency
can be adjusted independently for both non-reflective surfaces (typically an
object's edge shadows shown when side-lit) and top-lit surfaces (see second
example below).
3D Lighting
The 3D Lighting effect works in conjunction with other 3D effects to let you
vary the surface illumination and reflective properties.
