Constructor with topologicFaces, vertexIndex. | |
QgsMeshFace | currentFace () const |
Returns the current face, empty face if the circulator pass a boundary or circulator is invalid. | |
int | currentFaceIndex () const |
Returns the current face index, -1 if the circulator has passed a boundary or circulator is invalid. | |
int | degree () const |
Returns the degree of the vertex, that is the count of other vertices linked. | |
QList< int > | facesAround () const |
Returns all the faces indexes around the vertex. | |
bool | goBoundaryClockwise () const |
Sets the circulator on the boundary face turning clockwise, return false is there isn't boundary face. | |
bool | goBoundaryCounterClockwise () const |

bool | isValid () const |
Returns whether the vertex circulator is valid. | |
int | oppositeVertexClockwise () const |
Returns the opposite vertex of the current face and on the edge on the side turning clockwise. | |
int | oppositeVertexCounterClockwise () const |
Returns the opposite vertex of the current face and on the edge on the side turning counter clockwise. | |
int | turnClockwise () const |
Turns counter clockwise around the vertex and returns the new current face, -1 if the circulator pass a boundary or circulator is invalid. | |
int | turnCounterClockwise () const |
Turns counter clockwise around the vertex and returns the new current face, -1 if the circulator pass a boundary or circulator is invalid. | |
