[英]Maya + Python: Move pivot to bottom of bounding box
How can I move just the pivot of the selected node to the bottom of the bounding box? 如何仅将所选节点的枢轴移动到边界框的底部?
# Move the pivot for each selected not to it's center then bottom
import maya.cmds as cmds
curSel = cmds.ls(long = True, selection = True, type = 'dagNode')
for n in curSel:
bbox = cmds.exactWorldBoundingBox(n)
cmds.xform(n, cp=1)
bbox
is a 6-element list of XYZ min and XYZ max : [xmin, ymin, zmin, xmax, ymax, zmax]
. bbox
是XYZ min和XYZ max的6元素列表: [xmin, ymin, zmin, xmax, ymax, zmax]
。 If you want the pivot point to be the bottom center, you'll want the average X, minimum Y, and average Z: 如果希望将枢轴点作为底部中心,则需要平均值X,最小值Y和平均值Z:
bbox = cmds.exactWorldBoundingBox(n)
bottom = [(bbox[0] + bbox[3])/2, bbox[1], (bbox[2] + bbox[5])/2]
cmds.xform(n, piv=bottom, ws=True)
