# Blender.Modifier module and the Modifier PyType object """ The Blender.Modifier submodule B{New}: - provides access to Blender's modifier stack 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 @type Types: readonly dictionary @var Types: Constant Modifier dict used for L{ModSeq.append} to a modifier sequence and comparing with L{Modifier.type}: - ARMATURE - type value for Armature modifiers - BOOLEAN - type value for Boolean modifiers - BUILD - type value for Build modifiers - CURVE - type value for Curve modifiers - DECIMATE - type value for Decimate modifiers - LATTICE - type value for Lattice modifiers - SUBSURF - type value for Subsurf modifiers - WAVE - type value for Wave modifiers - EDGESPLIT - type value for Edge Split modifiers @type Settings: readonly dictionary @var 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 and Curve (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) - TYPES - Used for Subsurf only. Determines the subdivision algorithm. Integer: 0 = Catmull-Clark; 1 = simple subdivision. - 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. - OPTIMAL - Used for Subsurf only (bool). Enables Optimal Draw. - UV - Used for Subsurf only (bool). Enables Subsurf UV. - OBJECT_OFFSET - Used for Array only (Object) - OBJECT_CURVE - Used for Array only (Curve Object) - OFFSET_VEC - Used for Array only (3d Vector) - SCALE_VEC - Used for Array only (3d Vector) - MERGE_DIST - Used for Array only (float) - ENVELOPES - Used for Armature only (bool) - START - Used for Build only (int) - 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]) - STARTX - Used for Wave only (float [-100.0 - 100.0]) - STARTY - Used for Wave only (float [-100.0 - 100.0]) - 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) """ class ModSeq: """ The ModSeq object ================= This object provides access to list of L{modifiers} for a particular object.
