Member Function Documentation

_getNextTriangle()

virtual GenericTriangle* cloudViewer::GenericMesh::_getNextTriangle ( )

pure virtual

Returns the next triangle (relatively to the global iterator position)

Virtual method to handle the mesh global iterator. Global iterator position should be increased each time this method is called. The returned object can be temporary.

Returns

a triangle

Implemented in PyGenericMesh< GenericMeshBase >, PyGenericMesh< cloudViewer::GenericIndexedMesh >, ccSubMesh, ccMeshGroup, cloudViewer::geometry::ecvMeshBase, ccMesh, cloudViewer::SimpleMesh, and cloudViewer::Delaunay2dMesh.

forEach()

virtual void cloudViewer::GenericMesh::forEach ( genericTriangleAction  action )

pure virtual

Fast iteration mechanism.

Virtual method to apply a function to the whole mesh

Parameters

action

function to apply (see GenericMesh::genericTriangleAction)

Implemented in ccSubMesh, ccMeshGroup, cloudViewer::geometry::ecvMeshBase, ccMesh, cloudViewer::SimpleMesh, and cloudViewer::Delaunay2dMesh.

getBoundingBox()

virtual void cloudViewer::GenericMesh::getBoundingBox ( CCVector3 &  bbMin, CCVector3 &  bbMax  )

pure virtual

Returns the mesh bounding-box.
