Point Surface Sub-Object

Point surface sub-objects are similar to object-level point surfaces. The points are constrained to lie on the surface.

• Select a NURBS object. > Modify panel > Create Surfaces rollout > Point Surf
• Select a NURBS object. > Modify panel > NURBS toolbox > (Create Point Surface)
• Select a NURBS object. > Modify panel > Right-click a viewport. > Tools 2 (lower-left) quadrant > Create Point Surface

Procedures

To create a point surface sub-object:

1. In the NURBS toolbox, turn on (Create Point Surface).
2. In a viewport, drag to specify the initial area of the point surface.
3. 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.
