Keyboard Entry rollout
The Keyboard Entry rollout lets you create a
point surface by ty ping. Use the TAB key to move
betweenthecontrolsonthisrollout.Toclickthe
Create button f rom the keyboard, press ENTER
while the button is active.
X, Y, and Z—Let you enter the coordinates of the
center of the surface.
Length and W idth—Let you enter t he dimensions
of the surface in current 3ds Max units.
Length Points—Lets you enter the number of points
along the length of the surface (this is the initial
number of point columns).
Width Points—Lets you enter the number of points
along the width of the surface (this is the initi al
number of point rows).
Cr e ate —Creates the surface object.
Create Parameters rollout
Lengt h—The length of the surface in current
3ds Max units.
Width—The width of the surface in current
3ds Max units.
On the Modify panel, the Length and Width
spinners are no longer available. You can change
the length or width of the surface by scaling the
surface at the Surface sub-object level. Moving
point sub-objects also alters the length and width
of the surface.
Length Poi nt s—The number of points along the
length of the sur face. In other words, the init ial
number of point columns in the surface. Range=2
to 50. Default=4.
Width Points—The number of points a long the
width of the surface. In other words, the initial
number of point rows in the surface. Range=2 to
50. Default=4.
On the Modify panel, the point Lengt h and Width
spinners are no longer available. You can change
thenumberofrowsandcolumnsbydeleting
existing rows and columns, or by adding new rows
and columns using the Refine controls at the Point
sub-object level.
Genera te M appi ng Coordina tes—Generates
mapping coordinates so you can apply mapped
materials to the surface.
