blender操作模型数据的若干代码
1. 导出obj:

file_loc = 'mm_frame.obj'
imported_object = bpy.ops.import_scene.obj(filepath=file_loc)
obj_object = bpy.context.selected_objects[0]
bpy.ops.object.mode_set(mode="EDIT")
bpy.ops.mesh.subdivide(number_cuts=2)
bpy.ops.object.mode_set(mode="OBJECT")
bpy.data.objects['Cube'].select_set(True)
bpy.ops.object.delete()
imported_object = bpy.ops.import_scene.obj(filepath=file_loc)
obj = bpy.context.window.scene.objects[2]
print(obj)
bpy.context.view_layer.objects.active = obj
bpy.ops.object.mode_set(mode="EDIT")
bpy.ops.mesh.subdivide(number_cuts=2)
