Before I am getting too deep into AN, I would like find out if there is ability to offset perpendiculary original spline by one of planes(xy, xz, yz), by using same control points? Is there also ability to control(translate, rotate, scale) particular control point in spline?

  • $\begingroup$ Never used Animation nodes so can't answer there, but Blender's curves have builtin Offset property in the Object Data options. It is limited though, and wont affect all features. $\endgroup$ – Duarte Farrajota Ramos Mar 11 '17 at 20:11

You can offset the spline along whatever axis you want using the Transform Spline node, all control points are maintained.

Offset

To change the location of control points, use the Spline Info node to get the location of the control points, perform whatever transformation you want to do and create a spline from the result again using the Spline From Points node:

Transform
