+Then we rotate it around a point (0.,0.) by 90 degrees clockwise.
+\snippet MEDCouplingExamplesTest.cxx CppSnippet_MEDCouplingPointSet_rotate_2
+Next, we make a 3D mesh from the 2D one and rotate it around the Z axis by 90 degrees

+\snippet MEDCouplingExamplesTest.cxx CppSnippet_MEDCouplingPointSet_rotate_3

+<br><h2> Getting a minimum box bounding nodes </h2>
+
+First, we create a 3D mesh with 2 nodes, so that the first one has minimal coordinates and
+the second one has maximal coordinates.
+\snippet MEDCouplingExamplesTest.cxx CppSnippet_MEDCouplingPointSet_getBoundingBox_1
+Now we get a bounding box enclosing these nodes. This bounding box should contain
+coordinates of our two nodes (but in "no interlace" mode), as the nodes coincide with

+\snippet MEDCouplingExamplesTest.cxx CppSnippet_MEDCouplingPointSet_getNodeIdsNearPoint_1
+Now we define an array of coordinates of a point close to nodes #0, #2 and #4.
+
+Thus we expect that 
+\ref ParaMEDMEM::MEDCouplingPointSet::getNodeIdsNearPoint "getNodeIdsNearPoint()" that
+we are going to use,
+if called with \b eps = 0.003, would return ids of nodes #0, #2 and #4.

+"MEDCouplingUMesh" with 7 nodes and no cells.
+\snippet MEDCouplingExamplesTest.cxx CppSnippet_MEDCouplingPointSet_getNodeIdsNearPoints_1
+Now we define an array of coordinates of 3 points near which we want to find nodes of the mesh.
+- Point #0 is at distance 0.001 from the node #1.
+- Point #1 is rather far from all nodes.
+- Point #2 is close to nodes #3, #4 and #5.
+
+Thus we expect that 
+\ref ParaMEDMEM::MEDCouplingPointSet::getNodeIdsNearPoints "getNodeIdsNearPoints()" that
+we are going to use,

+\snippet MEDCouplingExamplesTest.cxx CppSnippet_MEDCouplingPointSet_getNodeIdsNearPoints_2
+\b idsIndex returns [0, 1, 1, 4] which means that:
+- Point #0 is close to 1 (== \b idsIndex[1] - \b idsIndex[0]) node whose id is 
+\b ids[ \b idsIndex[ 0 ]].
+- Point #1 is close to 0 (== \b idsIndex[2] - \b idsIndex[1]) nodes.
+- Point #2 is close to 3 (== \b idsIndex[3] - \b idsIndex[2]) nodes whose ids are

+and 3 nodes (#0, #2 and #5) have distance less than 0.004 between them.
+\snippet MEDCouplingExamplesTest.cxx CppSnippet_MEDCouplingPointSet_findCommonNodes_1
+Then, we use \ref ParaMEDMEM::MEDCouplingPointSet::findCommonNodes() "findCommonNodes()" to find
+coincident nodes, and check that (1) calling 
+\ref ParaMEDMEM::MEDCouplingPointSet::findCommonNodes() "findCommonNodes()" with \b prec
