Displace used to change the surface in the container
The Displace space warp acts as a force field to push and reshape an object's
geometry. Displace affects both geometry (deformable objects) and particle
systems. There are two basic ways to use the Displace space warp:
■ Apply the gray scale of a bitmap to generate the displacement amount.
Black areas of the 2D image are not displaced. Whiter areas push outward,
causing a 3D displacement of geometry.
■ Apply displacement directly by setting displacement Strength and Decay
values.
The Displace space warp works similarly to the Displace modifier, except that,
like all space warps, it affects world space rather than object space. Use the
Displace modifier when you need to create detailed displacement of a small
number of objects. Use the Displace space warp to displace particle systems,
a large number of geometric objects at once, or an object relative to its position
in world space.
For geometry, the detail of the displacement depends on the number of
vertices. Use the Tessellate modifier to tessellate faces you want to show in
greater detail.
