In this experiment, I’m trying to use data recorder to change components on a surface. The component part is a standart triangular construction, but the attractor points are defined by a 2D slider that is connected to a data recorder. Data recorder remembers last 15 points, while you move the 2d slider, last 15 points are projected on the base surface. This creates an illusion as if a “snake” game on a surface. Definition then uses the closes point distance method to calculate a parameter and uses it to amplify normal vectors at each subdivision of base surface. Drawing the component is based on the standart data list matching. You may check the definition here [GHX: 0.8.0066]. Of course the base surface is also associative, may be any shape, you have to define the “base surface” input first.
