# Blender.Lattice module and the Lattice PyType object

"""
The Blender.Lattice submodule.

Lattice Object
==============

This module provides access to B{Lattice} object in Blender.

Example::
  import Blender
  from Blender import Lattice
  from Blender.Lattice import *
  from Blender import Object
  from Blender import Scene

  myOb = Object.New('Lattice')
  myLat = Lattice.New()
  myLat.setPartitions(5,5,5)
  myLat.setKeyTypes(LINEAR, CARDINAL, BSPLINE)
  myLat.setMode(OUTSIDE)

  for y in range(125):
    vec = myLat.getPoint(y)
    co1 = vec[0] + vec[0] / 5
    co2 = vec[1] - vec[2] * 0.3
    co3 = vec[2] * 3
    myLat.setPoint(y,[co1,co2,co3])

  myOb.link(myLat)
  mySphere = Object.Get('Sphere')
  myOb.makeParent([mySphere])

  myLat.applyDeform()

  sc = Scene.getCurrent()
  sc.link(myOb)
  Blender.Redraw()
