From c7d8d289396e969b8a58e87d1dbcac7d81ddba0c Mon Sep 17 00:00:00 2001 From: Daniel Salazar Date: Tue, 19 Jul 2011 13:27:05 +0000 Subject: [PATCH] Object Align operator now correctly computes a *global* bounding box for all objects. This makes rotated or scaled objects work like they should. Now it's still derived from object's bounding box so it will not be completly acurate on complex objects.. to solve this Id need to cycle over all verts. Don't think that's a good idea to do in py --- .../startup/bl_operators/object_align.py | 128 ++++++++++++------ 1 file changed, 85 insertions(+), 43 deletions(-) diff --git a/release/scripts/startup/bl_operators/object_align.py b/release/scripts/startup/bl_operators/object_align.py index 3202a717001..8bf5cc9e8fb 100644 --- a/release/scripts/startup/bl_operators/object_align.py +++ b/release/scripts/startup/bl_operators/object_align.py @@ -21,13 +21,52 @@ import bpy from mathutils import Vector +def GlobalBB(bb_world): + # Initialize the variables with the 8th vertex + left, right, front, back, down, up =\ + bb_world[7][0],\ + bb_world[7][0],\ + bb_world[7][1],\ + bb_world[7][1],\ + bb_world[7][2],\ + bb_world[7][2] + + # Test against the other 7 verts + for i in range (7): + + # X Range + val = bb_world[i][0] + if val < left: + left = val + + if val > right: + right = val + + # Y Range + val = bb_world[i][1] + if val < front: + front = val + + if val > back: + back = val + + # Z Range + val = bb_world[i][2] + if val < down: + down = val + + if val > up: + up = val + + return (Vector((left, front, up)), Vector((right, back, down))) + def align_objects(align_x, align_y, align_z, align_mode, relative_to): cursor = bpy.context.scene.cursor_location -
