Island Analysis and Voxel Visualization

Island analysis identifies disconnected or unsupported regions across layers.

What the feature does

• Scans transformed model geometry layer-by-layer.
• Labels island regions per layer.
• Builds 3D voxel visualizations from scan labels.

Voxel visualization notes

• Each island can be rendered as instanced voxels instead of a smooth mesh overlay.
• The voxel approach maps directly to the labeled scan grid, which keeps the display faithful to the underlying data.
• Useful color schemes include unique colors, lifecycle coloring, and height gradients.

Visualization modes

• Unique colors: each island gets a distinct color.
• Lifecycle: differentiates merged vs active islands.
• Height gradient: visual grouping by vertical position.

Interaction

• Select islands for focused inspection.
• Filter merged islands when debugging structure.
• Adjust opacity for clarity in dense scenes.

Coordinate behavior

Scan outputs are derived from transformed world-space geometry. Rendering follows the scan positioning policy to avoid double-applying rotation/lift transforms.
