In-Depth Information
By changing the setting for the parallel seg-
ments to Knots (and selecting the curves in
the same order as we did in Figure 12-2),
the “long” curves now have their segments
weighted according to where the curve's
knots are. (This preserves the subtle slope
of the tip of our dingus.)
parallel segments, we can “sculpt” the
ways our segments lay over our surface.
(LightWave interpolates its segmentation in
a “connect-the-knots” fashion.)
Note
You've probably noticed that the direction in
which you select the curves (clockwise or
counterclockwise) determines whether the
normals of the polys that are created will be
facing toward or away from you. You've
probably also noticed that the convention
established by selecting points to make poly-
gons is reversed here when selecting curves
to make patches.
It's not really a big deal — just something
to be aware of.
Note
You add points to a curve or a polygon by
selecting it and then activating Multiply |
Subdivide | Add Points. A new point will be
added wherever you click on the selected
curve(s) or polygon(s).
