How to control Anemone Curve Growth?

Hello everyone,

I am currently working on a project to create “growing clothing” using the Anemone plugin. The definition uses Newton’s First and Second Laws to simulate the growth of curves.

As a Grasshopper beginner, I built most of this logic by following YouTube tutorials, but I have hit a wall and would appreciate some guidance.

The growth starts from the waist. My goal is to design a dress (although the mannequin in the file is male for now). The current Anemone loop consists of complex vector calculations.

My main question is: How can I control the overall silhouette of these growing curves?

I want to achieve the following controls:

  1. Collision Avoidance: The curves must not penetrate the human body mesh.

  2. Shape Control: I want to guide the growth into specific shapes, such as an hourglass (cinched waist), a straight column, or a wide-spreading skirt.

Since I am a beginner, I am finding it very difficult to control the global direction of the vectors to achieve these forms.

Any advice, keywords, or simple examples from the experts here would be greatly appreciated.

I have attached the Grasshopper file which includes the mesh mannequin.

Thank you in advance!
