Hi guys  how can I get geometry vertices , in three.js i can get positions with box.geometry.vertices  and returns coordinate for 8 points ( of a box ) ; now via Bjs i tried to use box.getVerticesData(BABYLON.VertexBuffer.PositionKind);  , but seems returns 24 points ! am I wrong or Babylon js use duplicate/separate vertices for each face ! if so , how can I avoid to return duplicated coordinate ? thanks in advance .
