Mesh::MVertSeq Class Reference

List of all members.


Detailed Description

The MVertSeq object
===================
      This object provides sequence and iterator access to the mesh's vertices.
      Access and assignment of single items and slices are also supported.
      When a single item in the vertex list is accessed, the operator[] returns
      a MVert object which "wraps" the actual vertex in the mesh; changing any
      of the vertex's attributes will immediately change the data in the mesh.
      When a slice of the vertex list is accessed, however, the operator[]
      returns a list of PVert objects which are copies of the mesh's vertex
      data.  Changes to these objects have no effect on the mesh; they must be
      assigned back to the mesh's vertex list.

      Slice assignments cannot change the vertex list size.  The size of the
      list being assigned must be the same as the specified slice; otherwise an
      exception is thrown.

      Example::
            import Blender
            from Blender import Mesh

            me = Mesh.Get("Plane")          # get the mesh data called "Plane"
            vert = me.verts[0]              # vert accesses actual mesh data
            vert.co[0] += 2                 # change the vertex's X location
            pvert = me.verts[-2:]           # pvert is COPY of mesh's last two verts
            pvert[0].co[0] += 2             # change the vertex's X location
            pvert[1].co[0] += 2             # change the vertex's X location
            me.verts[-1] = pvert[1]         # put change to second vertex into mesh

      @note: The mesh can be "cleared" by assigning B{None} to the mesh's vertex
      list.  This does not delete the Blender mesh object, it only deletes all
      the memory allocated to the mesh.  The result is equivalent to calling 
      Mesh.New().  The intent is to allow users writing exporters to free memory
      after it is used in a quick and simple way.

      Example::
            import Blender
            from Blender import Mesh

            me = Mesh.Get("Plane")          # get the mesh data called "Plane"
            me.verts = None                 # delete all the mesh's attributes
