Detailed Description

template<class TriMeshType, class PolyMeshType>
class vcg::tri::PolygonSupport< TriMeshType, PolyMeshType >

This class is used convert between polygonal meshes and triangular meshes.

This class contains two members that allow to build a triangular mesh from a polygonal mesh and viceversa. In a trimesh, the generic polygons with n sides are codified represented by tagging the internal edge of the face as 'faux' with the SetF.

static void vcg::tri::PolygonSupport< TriMeshType, PolyMeshType >::ExtractPolygon	(	typename TriMeshType::FacePointer	tfp,
		std::vector< typename TriMeshType::VertexPointer > &	vs,
		std::vector< typename TriMeshType::FacePointer > &	fs
	)		[inline, static]

Collect tris and verts of a polygonal face marked by FauxEdges.

Given a face pointer, it builds a vector with all the face and vertex pointers around the polygonal face determined by the current FAUX-EDGE markings. It assumes that the mesh is 2Manifold and has FF adjacency already computed per face visited flag cleared. NOTE: All the faces touched are marked as visited and it assumes that you do not call this function on a visited face.

Import a trianglemesh from a polygon mesh

static void vcg::tri::PolygonSupport< TriMeshType, PolyMeshType >::ImportFromTriMesh	(	PolyMeshType &	pm,
		TriMeshType &	tm
	)		[inline, static]

Import a polygon mesh from a triangle mesh.

It assumes that the mesh has the faux edges bit set for a polygonal mesh and that have the FFAdjacency already computed.

static void vcg::tri::PolygonSupport< TriMeshType, PolyMeshType >::MergeFlatFaces	(	TriMeshType &	tm,
		double	tolerance = 0.1E-4
	)		[inline, static]

Given a tri mesh (with per-face normals and FF connectivity), merges flat faces into larger polygons. The merging is done only by setting the faux bit
