Point Surface Sub-Object 1181
Clo se Cols. —
Closes the surface by joining the ends
of its columns.
Rebuild—Displays the Rebuild CV Surface dialog
(page 1–1236), which lets you specif y how to
rebuild the surface. Rebuilding the surface can
change its appearance.
Reparameterize—Displays t he Reparameterize
dialog (page 1–1237). Reparameterizing a surface
changes the surface ’s parameter space (page 3–988)
to provide a better relation between control point
locations and the shape of the surface.
Tip: It is a good idea to reparameterize after you
have added CVs to the surface by refining or
inserting.

Point surface sub-objects are simi lar to object-level
point surfaces (page 1–1102).Thepointsare
constrained to lie on the surface.

Procedure
To create a point s ur fa ce s ub-object:
1.
InaNURBSobject,turnonPointSurf
on the Create Surfaces rollout or Create Point
Surface in the toolbox.
2. In a viewport, drag to spe cify the initial area of
the point surface.
3. Adjust the point surface’s creation parameters.
Interfa ce
The parameters that appear when you create a
point su rface sub-object differ from those you see
when you modify it as a sub-object.
Point Surface rollout (creation time)
Lengt h—The length of the surface in c ur rent
3ds Max units.
Width—The width of the surface in current
3ds Max units.
Length Poi nts —The number of points a long the
length of the surface. In other words, the initial
number of point columns in the surface. Range=2
to 50. D efault=4.
Width Points—The number of points along the
width of the surface. In other words, the initial
number of point rows in the surface. Range=2 to
50. Default=4.
Genera te M apping Coordinates—Generates
mapping coordinates so you can apply mapped
materials to the surface.
Flip Normals—Turn on to reverse the direction of
the sur face normals.
