  //! Creates an array of triangle strips,

  //! myArray = Graphic3d_ArrayOfTriangleStrips(7)
  //! myArray->AddVertex(x1,y1,z1)
  //! ....
  //! myArray->AddVertex(x7,y7,z7)
  //! 2) creating separate strips defined with a predefined
  //! number of strips and the number of vertex per strip.
  //! i.e:
  //! myArray = Graphic3d_ArrayOfTriangleStrips(8,2)
  //! myArray->AddBound(4)
  //! myArray->AddVertex(x1,y1,z1)
  //! ....
  //! myArray->AddVertex(x4,y4,z4)
  //! myArray->AddBound(4)
  //! myArray->AddVertex(x5,y5,z5)
  //! ....
  //! myArray->AddVertex(x8,y8,z8)
  //!
  //! <maxVertexs> defined the maximun allowed vertex number in the array.
  //! <maxStrips> defined the maximun allowed strip number in the array.
  //! The number of triangle really drawn is :
  //! VertexNumber()-2*Min(1,BoundNumber())
  //! Warning:
  //! When <hasVNormals> is TRUE , you must use one of
  //! AddVertex(Point,Normal)
  //! or  AddVertex(Point,Normal,Color)
  //! or  AddVertex(Point,Normal,Texel) methods.
  //! When <hasVColors> is TRUE , you must use one of
  //! AddVertex(Point,Color)
  //! or  AddVertex(Point,Normal,Color) methods.
  //! When <hasTexels> is TRUE , you must use one of
  //! AddVertex(Point,Texel)
  //! or  AddVertex(Point,Normal,Texel) methods.
  //! When <hasBColors> is TRUE , <maxBounds> must be > 0 and
  //! you must use the
  //! AddBound(number,Color) method.
  //! Warning:
  //! the user is responsible about the orientation of the strip
  //! depending of the order of the created vertex and this
  //! orientation must be coherent with the vertex normal optionnaly
  //! given at each vertex (See the Orientate() methods).
