(World Space) converts a
NURBS (page 1–1079)
objectintoamesh. Ifadisplacementmapis
applied to the object, the mesh shows the effect of
the displacement map in viewports. There are two
main reasons for using Displace NURBS:
• As a visualization aid to see the effect of a
displacement map in viewports
When you use Displace NURBS this way,
you usually delete the modifier once you’ve
obtained the effect you want.
• To obtain an editable mesh created from a
displacement map on a NURBS object

use the
Snapshot command (page 1–438) from
the Tools menu, and choose Mesh as the Clone
Method.
Snapshot creates a permanently displaced mesh.
As it does for other k inds of objects, Snapshot
also leaves the original, displacement-mapped
object in the scene. After applying Snapshot,
you can delete the or iginal object, or you can
keep it in your scene to use for other purposes.

The rollout for Displace NURBS lets you choose
which surface approximation settings are used to
produce the mesh.
Animated Displacement M ap—If you use an
animat ed displacement map on the mesh, turn
on this toggle to have the NURBS Modifier
correctly update the mesh as the displacement
map animates.
