Some future Wip! :)
To evolve this surface modeling tool into a more comprehensive industrial solution, here are several key features that would provide significant added value:
1. Surface Analysis & Quality Control – Normal Inversion: A button to visualize and flip the orientation of surface normals. Draft Analysis: A color-coded shader (false-color mapping) to verify if the surface can be demolded along a specific axis. Curvature Display: A visualization mode using curvature combs on isoparametric curves (U/V) or a mean/Gaussian curvature map.
2. Advanced Editing & Manipulation – Mirroring: A button to duplicate control points across a plane ($XY$, $XZ$, $YZ$) for real-time symmetrical part design. Smooth / Relax: A function to refine the distribution of selected control points and eliminate local bumps. Numerical Input (Inp3D): A panel for directly entering exact coordinates ($X, Y, Z$) for selected control points.
3. Continuity & Topology – Continuity Management (G0, G1, G2): Automatic constraints on point rows to ensure tangent ($G1$) or curvature-continuous ($G2$) connections between surface patches. Dynamic Creation: The ability to add or insert new profile curves directly from the interface without reloading a JSON/IGES file.
4. Ergonomics & Workflow – Snapping: Snap control points to a 3D grid or align them along axes (X, Y, Z) with a single click. History (Undo/Redo): A state manager (Ctrl+Z / Ctrl+Y shortcuts) for safe point manipulation. Scene Hierarchy: A collapsible list displaying each curve and its points, allowing you to hide, lock, or rename them.
