Detailed Description

Merge connected coplanar faces into a general polygon face.

Todo

Support faces with holes (i.e., polygons with multiple contours)

Member Function Documentation

apply()

void apply	(	SurfaceMesh *	mesh,
		float	angle_threshold = 1.0f )

Merges connected coplanar faces into a general polygon face.

The result is a general polygonal mesh.

Parameters

mesh	The input surface mesh. Upon return, the mesh will be modified.
angle_threshold	Two faces sharing a common edge are considered coplanar if the dihedral angle is smaller than angle_threshold (in degrees).

Attention

The current implementation doesn't support polygon faces with holes.

merge_colinear_edges()

void merge_colinear_edges	(	SurfaceMesh *	mesh,
		float	angle_threshold = 1.0f )

Removes 2-degree vertices.

For every 2-degree vertex, if the angle between its two incident edges is smaller than a threshold, merge the two incident edges by removing this vertex.

Parameters

mesh	The input surface mesh. Upon return, the mesh will be modified.
angle_threshold	Two edges sharing the same vertex are considered colinear if their angle is smaller than angle_threshold (in degrees).
