Detailed Description

template<class UpdateMeshType>
class vcg::tri::UpdateQuality< UpdateMeshType >

Generation of per-vertex and per-face qualities.

It works according to various strategy, like geodesic distance from the border (UpdateQuality::VertexGeodesicFromBorder) or curvature ecc. This class is templated over the mesh and (like all other Update* classes) has only static members; Typical usage:

MyMeshType m;
UpdateQuality<MyMeshType>::VertexGeodesicFromBorder(m);

Member Function Documentation

FaceArea()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::FaceArea ( MeshType &  m )

inlinestatic

Assign to each face of the mesh its area.

FaceConstant()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::FaceConstant ( MeshType &  m, FaceQualityType  q  )

inlinestatic

Assign to each face of the mesh a constant quality value. Useful for initialization.

FaceNormalize()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::FaceNormalize ( MeshType &  m, FaceQualityType  qmin = 0.0, FaceQualityType  qmax = 1.0  )

inlinestatic

Normalize the face quality so that it fits in the specified range.

VertexClamp()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::VertexClamp ( MeshType &  m, VertexQualityType  qmin, VertexQualityType  qmax  )

inlinestatic

Clamp each vertex of the mesh with a range of values.

VertexConstant()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::VertexConstant ( MeshType &  m, VertexQualityType  q  )

inlinestatic

Assign to each vertex of the mesh a constant quality value. Useful for initialization.

VertexCurvednessFromCurvatureDir()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::VertexCurvednessFromCurvatureDir ( MeshType &  m )

inlinestatic

VertexCurvednessFromCurvatureDir Compute from the current Curvature Direction the Curvedness as defined by [Koenderink 1992] and store it in the per-vertex Quality. C = Sqrt((k1*k1+k2*k2)/2.0)

VertexNormalize()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::VertexNormalize ( MeshType &  m, VertexQualityType  qmin = 0.0, VertexQualityType  qmax = 1.0  )

inlinestatic

Normalize the vertex quality so that it fits in the specified range.

VertexSaturate()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::VertexSaturate ( MeshType &  m, ScalarType  gradientThr = 1.0  )

inlinestatic

Saturate Vertex Quality Saturate the vertex quality so that for each vertex the gradient of the quality field is lower than the given threshold value (in absolute value) The saturation is done in a conservative way (quality is always decreased and never increased)

Note: requires VF adjacency.

VertexShapeIndexFromCurvatureDir()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::VertexShapeIndexFromCurvatureDir ( MeshType &  m )

inlinestatic

VertexShapeIndexFromCurvatureDir Compute from the current Curvature Direction the Shape Index S as defined by [Koenderink 1992] and store it in the per-vertex Quality. S = 2/pi atan(k1+k2/k1-k2)

VertexValence()

template<class UpdateMeshType >

static void vcg::tri::UpdateQuality< UpdateMeshType >::VertexValence ( UpdateMeshType &  m )

inlinestatic

Assign to each vertex of the mesh the valence of faces.
