Normalize Spline Modifier 739
Procedure
To use the nor mal modifi er:
1.
Select an objec t , then on the Modify
panel, choose Mesh Editing > Normal from the
Modifier List.
The object appears to turn inside-out, since
FlipNormalsisonbydefault.
2. If the object has some faces pointing inward
and others outward, turn on Unify Normals to
mak e all the faces point similarly.
Tip: To flip or unify normals on portions of
objects, convert to Editable Mesh and select
Faces or Polygons. On the Surface Properties
rollout in the Normals group, use the Flip and
Unify buttons.
Inter face
Unify Normals—Unifiesthenormalsofanobjectby
flipping the normals so that they all point in the
same direction, usually outward. This is u seful
for restoring an object’s faces to their original
orientations. Sometimes normals of scenes that
have come into 3ds Max as par t of a DWG or DXF
file are irregular, depending on the metho ds used
to create the scene. Use this option of the modifier
to correct them.
Flip Normals—Reverses the direction of a ll the
surface normals of the faces of the selected object
or objects. Default=on.
Normalize Spline Modifier
Selec t a spline objec t. > Modify panel > Modifier List
> Normalize Sp l.
Select a spline object. > M odifiers menu > Patch/Spline
Editing > Normalize Spline
The spline on the left has been n or malized.
The Normalize Spline modifier adds new control
points in the spline at regular intervals. Use
Normalize Spline to produce splines for motion
paths that require constant velocity.
Note: This feature is not animatable.
Interf ace
Seg Length—Sets the length of the spline’s
segments, in 3ds Max u nits. The positions of the
original vertices are discarded, and vertices are set
to regular intervals. Segment length determines
how many cont rol points are added: shorter
segments result in more control points, longer
segments result in fewer. Default=20.0 units.
