This Geometry Nodes setup performs adaptive subdivision on a base mesh based on drawn surface curves. Users can control the subdivision density through a threshold value and utilize a distribution parameter to manage the spread of the subdivision levels. The tool includes controls to offset the curves from the mesh normals, alongside settings to compress or extend the nearby mesh geometry using linear or powered falloff shapes. The project includes two versions: one tailored for Blender 3.6 supporting up to six levels of subdivision, and a Blender 4.0 version that leverages the Repeat Zone node to allow for unlimited subdivision levels.
