Overlapping Faces#

Description#

Overlapping faces visualization

Overlapping faces are two or more faces that occupy the same spatial region (coplanar or nearly coplanar and overlapping in projection).

Detection#

Detection Method: Spatial overlap detection using AABB and coplanarity checks

Algorithm:

  1. For each pair of faces: - Check if bounding boxes overlap significantly - Test if faces are coplanar (or nearly coplanar within tolerance) - If coplanar, check if 2D projections overlap

  2. Report overlapping face pairs with overlap region coordinates

Tolerance: Implicit (based on face planarity classification)

Auto-Repair#

Status: ❌ No automatic repair

Action: Detection and reporting only

Manual Fix / Avoidance#

In 3D Modelling tools (Before Export):

  1. Remove duplicates: - Delete obviously duplicate faces - If for example, a room floor overlaps with a sofa bottom face, remove one of the faces and connect the remaining face to the mesh properly
