Editable Mesh (Object) controls are available when no sub-object levels are active. These controls are also available at all
sub-object levels, and work the same at each level, except as noted in Edit Geometry Rollout (Mesh).
Surface Properties rollout
Specifies surface approximation settings for subdividing the editable mesh. These controls work like the surface approximation settings for NURBS surfaces. They are used when you apply a Displacement map to the editable mesh.
The Surface Properties rollout is available only for editable mesh objects; it does not appear in the Modify panel for an
object to which the Edit Mesh modifier is applied. With Edit Mesh-modified objects, you can use the Disp Approx modifier
to the same effect.
- Subdivision Displacement
When on, faces are subdivided to accurately displace the mesh, using the method and settings you specify in the Subdivision
Presets and Subdivision Method group boxes. When off, the mesh is displaced by moving existing vertices, the way the Displace modifier does. Default=off.
- Split Mesh
Affects the seams of displaced mesh objects; also affects texture mapping. When on, the mesh is split into individual faces
before it is displaced; this helps preserve texture mapping. When off, the mesh is not split and an internal method is used
to assign texture mapping. Default=on.
This parameter is required because of an architectural limitation in the way displacement mapping works. Turning Split Mesh
on is usually the better technique, but it can cause problems for objects with clearly distinct faces, such as boxes, or even
spheres. A box's sides might separate as they displace outward, leaving gaps. And a sphere might split along its longitudinal
edge (found in the rear for spheres created in the Top view) unless you turn off Split Mesh. However, texture mapping works
unpredictably when Split Mesh is off, so you might need to add a Displace Mesh modifier
and make a snapshot
of the mesh. You would then apply a UVW Map modifier
and then reassign mapping coordinates to the displaced snapshot mesh.
Subdivision Presets group & Subdivision Method group
The controls in these two group boxes specify how the displacement map is applied when Subdivision Displacement is on. They
are identical to the Surface Approximation controls used for NURBS surfaces.
