Displace fixed SOP Surface with SpringSOP
When you want to deform the interior points of a SOP while maintaining the position of its outer edges, we can use GroupSOP and SpringSOP. Here's a step-by-step approach:
-
Create a Point Group Use the
GroupSOP
to collect the points you want to fix. Set theGroup Entity
to points. -
Select Interior Points Use a bounding box to select all points except those on the outer edge of the shape.
-
Invert the Group In the Combine category, invert the group by setting
NOT
and assigning a new name like "dontmove". -
Apply Fixed Points in SpringSOP In the SpringSOP, navigate to the Nodes category and set the newly created group for the
Set Fixed Points
parameter.
This technique allows you to create controlled deformations while preserving the original boundary of your surface, giving you precise control over geometric transformations.
