Create Point Surface
Point surface sub-objects are similar to object-level point surfaces. The points are constrained to lie on the surface.
Procedures
To create a point surface sub-object:
- In the NURBS toolbox, turn on
(Create Point Surface).
- In a viewport, drag to specify the initial area of the point surface.
- Adjust the point surface's creation parameters.
Interface
The parameters that appear when you create a point surface sub-object differ from those you see when you modify it as a sub-object.
Point Surface rollout (creation time)
- Length
-
The length of the surface in current 3ds Max units.
- Width
-
The width of the surface in current 3ds Max units.
- Length Points
-
The number of points along the length of the surface. In other words, the initial number of point columns in the surface.
Range=2 to 50. Default=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.
- Generate Mapping Coordinates
-
Generates mapping coordinates so you can apply mapped materials to the surface.
- Flip Normals
-
Turn on to reverse the direction of the surface normals.
Point Surface rollout (modification time)
The close controls let you close a surface. They appear on the Point Surface rollout while an independent point surface sub-object
is selected. They have no effect if the surface is already closed in that direction.
- Close Rows
-
Closes the surface by joining the ends of its rows.
- Close Cols.
-
Closes the surface by joining the ends of its columns.
