Deform Teeter 365

Using t w ist to deform the lofted roadway

These are the properties of Twist deformation

cur ves:

• A single red curve determines shape rotation

about the path.

• The default curve value is 0 degrees of rotation.

• Positive values produce counterclockwise

rotation, when viewed from the start of the

path.

• Negative values produce clockwise rotation.

•Bothtwistdeformationandbankingproduce

rotation about the path. Twist rotation is added

to a shape after the banking angle is applied.

You can use Twist deformation to exaggerate or

reduce the amount of banking.

See Deformation D ialog (page 1–368) for specific

information on the dialog controls.

Procedure

To use Twist deformation:

Select a loft object.

2. Click Loft in the modifier stack dis play.

3. Click Twist on the Deformations rollout.

4. Editthesingledeformationcurvetospecify

rota tion about the path.

Teeter deformation rotates shapes about their local

X axis and Y axis. Teetering is what 3ds Max does

automatically when you select Contour on the Skin

Parameters rollout. Use Teeter deformation when

you want to manually control contour effects.
