GeoInspector is a professional mesh topology analysis add-on for Blender 4.x. It is designed specifically for 3D artists creating game-ready assets, providing real-time visualization and automated cleanup tools for common geometric issues.

KEY FEATURES

1. Comprehensive Geometry Detection

The add-on scans your mesh for several critical topology issues:

- N-gons: Faces with more than 4 vertices.

- Triangles: Exactly 3-sided faces.

- Non-Manifold Geometry: Edges shared by more than two faces or edges with inconsistent winding.

- Loose Geometry: Vertices not connected to any edges and edges not connected to any faces.

- Flipped Normals: Faces pointing inward, causing lighting and rendering errors.

- Near-Degenerate Triangles: Extremely thin triangles with area below a user-defined threshold.

- Non-Planar Faces: Faces whose vertices do not lie on a single flat plane.

- Degenerate Polygons: Zero-area faces or faces with duplicate vertices.

2. Real-time Visual Overlays

GeoInspector provides a high-performance GPU-accelerated overlay system:

- Color-Coded Highlights: Each issue type is assigned a unique, customizable color in the 3D viewport.

- Visibility Toggles: Easily hide or show specific issue types via the N-panel.

- Overlay Opacity: Adjust the transparency of highlights.

3. Integrated Cleanup Tools (Quick Fixes)

- Fix Flipped Normals: Automatically recalculates face orientations.

- Delete Loose Geometry: Instantly purges disconnected verts and edges.

- Triangulate/Flatten Non-Planar: Split non-planar faces or project them onto a flat plane.

- Fix Degenerate: Removes zero-area polygons and merges duplicate vertices.
