seampoints expression function
Lists all seam points in a surface node.
Replaced by: hou.Geometry
This function returns a string containing an ordered list of all seam points in the specified surface node. Seam points are created using the Cloth Seam surface node, and are identified by seam attributes on the points.
The whichside argument specifies which side of the seams we are interested in. The value can be either zero or one.
Calling this function once with a whichside parameter of zero, and once with a whichside parameter of one, will provide two lists of points where tying each point to the corresponding point in the other list fully describes all seams on the geometry.
