Parametric Fingerless Glove

Project developed during Rhino CAD 2 course, starting from a 3D scan of real objects.

FINGERLESS GLOVE

Parametric design of a fingerless glove using Grasshopper: leveraging this Rhino plugin, I developed a customizable system that automatically adjusts the glove size based on the user's specific measurements.

1. Sizing System

After removing the unwanted mesh parts, I based the model scale on the forearm and wrist circumferences. Using the Contour Node, I extracted the section curves and scaled the mesh points based on the centroids of these curves. To maintain a harmonious scale guided by two distinct parameters, each point's scale coefficient depends on its proximity to the two reference curves: this logic ensures results that preserve the natural proportions of the hand.

To implement the scaling system, I used the C# Script node (assisted by AI-generated code) to prevent program crashes. To further enhance the system, it would be necessary to add Z-axis scaling based on the distance between the middle fingertip and the palm-wrist junction, ensuring even more precise customization of the hand's longitudinal proportions.

2. Sizing System Visualization

Due to the heavy mesh geometry, real-time scaling visualization is difficult; below is the scaling visualization through contour curves.

3. Pattern

The image shows the mapping method for the surface pattern's origin points.

I was unable to apply the pattern directly to the mesh due to continuous Grasshopper crashes. I therefore had to bake both the pattern and the mesh (which I had previously offset by 2 millimeters). After baking, I converted the mesh to a NURBS surface using the MeshToNURB command, allowing me to perform the Boolean subtraction between the pattern cylinders and the glove.
