Module Modifier

The Blender.Modifier submodule

New:

This module provides access to the Modifier Data in Blender.

Example:
 from Blender import *

 ob = Object.Get('Cube')        # retrieve an object
 mods = ob.modifiers            # get the object's modifiers
 for mod in mods:
   print mod,mod.name           # print each modifier and its name
 mod = mods.append(Modifier.Types.SUBSURF) # add a new subsurf modifier
 mod[Modifier.Settings.LEVELS] = 3     # set subsurf subdivision levels to 3
Example:
       # Apply a lattice to an object and get the deformed object
       # Uses an object called 'Cube' and a lattice called 'Lattice'
       
       from Blender import *
       ob_mesh= Object.Get('Cube')
       ob_lattice= Object.Get('Lattice')

       myMeshMod = ob_mesh.modifiers
       mod = myMeshMod.append(Modifier.Types.LATTICE)
       mod[Modifier.Settings.OBJECT] = ob_lattice

       ob_mesh.makeDisplayList() # Needed to apply the modifier

       Window.RedrawAll() # View the change

       deformed_mesh= Mesh.New()
       deformed_mesh.getFromObject(ob_mesh.name)


       # Print the deformed locations
       for v in deformed_mesh.verts:
               print v.co

Classes
Modifier This object provides access to a modifier for a particular object accessed from ModSeq.
ModSeq This object provides access to list of modifiers for a particular object.

Variable Details

Settings

Constant Modifier dict used for changing modifier settings.
  • RENDER - Used for all modifiers (bool) If true, the modifier is enabled for rendering.
  • REALTIME - Used for all modifiers (bool) If true, the modifier is enabled for interactive display.
  • EDITMODE - Used for all modifiers (bool) If both REALTIME and EDITMODE are true, the modifier is enabled for interactive display while the object is in edit mode.
  • ONCAGE - Used for all modifiers (bool) If true, the modifier is enabled for the editing cage during edit mode.
  • OBJECT - Used for Armature, Lattice, Curve, Boolean and Array (Object)
  • VERTGROUP - Used for Armature, Lattice, Curve, Smooth and Cast (String)
  • LIMIT - Array and Mirror (float [0.0 - 1.0])
  • FLAG - Mirror and Wave (int)
  • COUNT - Decimator Polycount (readonly) and Array (int)
  • LENGTH - Build [1.0-300000.0] and Array [0.0 - 10000.0] (float)
  • FACTOR - Smooth [-10.0, 10.0] and Cast [-10.0, 10.0] (float)
  • ENABLE_X = Smooth and Cast (bool, default: True)
  • ENABLE_Y = Smooth and Cast (bool, default: True)
  • ENABLE_Z = Smooth and Cast (bool, default: True)
  • TYPES - Subsurf and Cast. For Subsurf it determines the subdivision algorithm - (int): 0 = Catmull-Clark; 1 = simple subdivision. For Cast it determines the shape to deform to = (int): 0 = Sphere; 1 = Cylinder; 2 = Cuboid
  • LEVELS - Used for Subsurf only (int [0 - 6]). The number of subdivision levels used for interactive display.
  • RENDLEVELS - Used for Subsurf only (int [0 - 6]). The number of subdivision levels used for rendering.

  • SEED - Used for Build only (int)
  • RANDOMIZE - Used for Build only (bool)
  • AXIS - Used for Mirror only (int [0 - 2])
  • RATIO - Used for Decimate only (float [0.0 - 1.0])

  • HEIGHT - Used for Wave only (float [-2.0 - 2.0])
  • WIDTH - Used for Wave only (float [0.0 - 5.0])
  • NARROW - Used for Wave only (float [0.0 - 10.0])
  • SPEED - Used for Wave only (float [-2.0 - 2.0])
  • DAMP - Used for Wave only (float [-1000.0 - 1000.0])
  • LIFETIME - Used for Wave only (float [-1000.0 - 1000.0])
  • TIMEOFFS - Used for Wave only (float [-1000.0 - 1000.0])
  • OPERATION - Used for boolean only (int 0,1,2 : Intersect, Union, Difference)
  • EDGESPLIT_ANGLE - Used for edge split only (float 0.0 - 180)
  • EDGESPLIT_FROM_ANGLE - Used for edge split only, should the modifier use the edge angle (bool)
  • EDGESPLIT_FROM_SHARP - Used for edge split only, should the modifier use the edge sharp flag (bool)
