Unlike smoothing, Relax works by only averaging the largest surface
anomalies so that the overall shape is maintained.
■ The Erase operation eliminates the effects of the other four operations.
The Erase operation works up to the last time you saved the scene or
clicked the Update button to the right of Erase Surface.
2 Experiment with each of the five operations on the surface. Don’t be
concerned with the results. Just become familiar with the response to
your mouse strokes.
By default, Push and Pull strokes deform the surface in a direction normal
(perpendicular) to the surface. To create the resulting deformation more
accurately, use Push and Pull strokes in a front, side, or top view while
examining the results in a separate perspective view. Tumble the
perspective view regularly for the best visual feedback.
When you position the mouse pointer on the surface, it changes to a red
sculpt icon that shows an abbreviation for the name of the operation
you are performing. For instance, Ps stands for Push.
The red icon also displays the radius of the region affected by the stroke.
The Radius(U) value changes the radius.
3 Select the Erase operation and click the Flood button. This erases all your
changes.
4 Select the Pull operation and enter a Radius(U) of 0.25, then drag between
a pair of horizontal isoparms without crossing either.
This has no effect because the stroke radius didn’t make contact with the
CVs of either isoparm. Regardless of which operation you use, only CVs
are affected by the strokes.
5 Change the Radius(U) to 2 and repeat the prior strokes.
