Detailed Description

template<typename BaseVecT>
class lvr2::Tesselator< BaseVecT >

Tesslation algorithm, utilizing the OpenGL tesselator to ease the reconstructed mesh. This algorithm is destryoing the mesh correlation between clusters, faces and vertices thus it is currently not suitable to run any algorithms requiring an coherent mesh.

Member Function Documentation

addTesselatedFaces()

template<typename BaseVecT >

static void lvr2::Tesselator< BaseVecT >::addTesselatedFaces ( BaseMesh< BaseVecT > &  mesh, ClusterBiMap< FaceHandle > &  clusters, DenseFaceMap< Normal< typename BaseVecT::CoordType >> &  faceNormal, ClusterHandle  clusterH  )

staticprivate

Adds the tesslated faces to the current cluster. Avoid any errors while adding duplicated vertices, it first removes all of the faces in the cluster, than removing the cluster itself and eventually creating an new one with the new tesslated faces.

apply()

template<typename BaseVecT >

static void lvr2::Tesselator< BaseVecT >::apply ( BaseMesh< BaseVecT > &  mesh, ClusterBiMap< FaceHandle > &  clusters, DenseFaceMap< Normal< typename BaseVecT::CoordType >> &  faceNormals, float  lineFusionThreshold  )

static

Retesselates the current mesh cluster by cluster.

beginCallback()

template<typename BaseVecT >

static void CALLBACK lvr2::Tesselator< BaseVecT >::beginCallback ( GLenum  type )

staticprivate

OpenGL callback, which is invoked by glBegin() to indicate the start of an primitiv.

combineDataCallback()

template<typename BaseVecT >

static void CALLBACK lvr2::Tesselator< BaseVecT >::combineDataCallback ( GLdouble  coords[3], void *  vertex_data[4], GLfloat  weight[4], void **  outData, void *  userData  )

staticprivate

OpenGL callback, which is called when the tesselator wants to create an new vertex on an intersection. This simply takes the coords and adds it as an new vertex to our interal list.

endCallback()

template<typename BaseVecT >

static void CALLBACK lvr2::Tesselator< BaseVecT >::endCallback ( void  )

staticprivate

OpenGL callback, which is invoked by glEnd() to indicate the end of an primitiv.

errorCallback()

template<typename BaseVecT >

static void CALLBACK lvr2::Tesselator< BaseVecT >::errorCallback ( GLenum  errno )

staticprivate

OpenGL callback, which is called on any error occurring while running the tesslation.

init()

template<typename BaseVecT >

static void lvr2::Tesselator< BaseVecT >::init ( )

staticprivate

Initalizes the tesselator object, deleting the old one if one is found and registering all necessary callbacks.

vertexCallback()

template<typename BaseVecT >

static void CALLBACK lvr2::Tesselator< BaseVecT >::vertexCallback ( void *  data )

staticprivate

OpenGL callback, which is called for every vertex, adding it to our internal list.
