Members

Member	Description
points	The two points of an edge in paint order
normals	Vertex normal if from a closed primitive boundary, averaged if appropriate, otherwise 0,0,0
texture_coord	The texture coordinates corresponding to 'points'
vertices	The corresponding vertex numbers if 'edge' is non-zero, otherwise 0
edge	The corresponding edge number, if appropriate, otherwise 0
winding_order_index	A pseudo primitive-local vertex id, or count.
boundary_id	Top-level containing the primitive's id. A change indicates going from a closed primitive's boundary to a hole, or from one hole to another.
edge_rgb	The edge color of the facet.
edge_type	The line width and style index of the facet.
