如何通过Python API在Blender 2.50中创建简单网格

我想通过pythonapi在Blender(2.50)中创建一个简单的mesh,但是API文档中的示例还不起作用。

我试过以下方法,但效果不好 from API 2.49

   from Blender import *
   import bpy

   editmode = Window.EditMode()    # are we in edit mode?  If so ...
   if editmode: Window.EditMode(0) # leave edit mode before getting the mesh

   # define vertices and faces for a pyramid
   coords=[ [-1,-1,-1], [1,-1,-1], [1,1,-1], [-1,1,-1], [0,0,1] ]  
   faces= [ [3,2,1,0], [0,1,4], [1,2,4], [2,3,4], [3,0,4] ]

   me = bpy.data.meshes.new('myMesh')          # create a new mesh

   me.verts.extend(coords)          # add vertices to mesh
   me.faces.extend(faces)           # add faces to the mesh (also adds edges)

   me.vertexColors = 1              # enable vertex colors 
   me.faces[1].col[0].r = 255       # make each vertex a different color
   me.faces[1].col[1].g = 255
   me.faces[1].col[2].b = 255

   scn = bpy.data.scenes.active     # link object to current scene
   ob = scn.objects.new(me, 'myObj')

   if editmode: Window.EditMode(1)  # optional, just being nice

这不起作用,因为网格对象没有任何 faces verts 成员。

有什么办法可以做吗?
