Detailed Description

IntersectingElement.

Adress polygon inside of ExPolygon Keep information about source of vertex:

• from face (one of 2 possible)
• from edge (one of 2 possible)

V1~~~~~V2 | f1 /: | / : e1| /e2: | / : |/ f2 : V1'~~~~V2'

| .. edge / .. edge : .. foreign edge - neighbor ~ .. no care edge - idealy should not cross model V1,V1' .. projected 2d point to 3d V2,V2' .. projected 2d point to 3d

Vertex indexing V1 .. i (vertex_base + 2x index of point in polygon) V1' .. i + 1 V2 .. j = i + 2 || 0 (for last i in polygon) V2' .. j + 1

f1 .. text_face_1 (triangle face made by side of shape contour) f2 .. text_face_2 e1 .. text_edge_1 (edge on side of face made by side of shape contour) e2 .. text_edge_2
