Maya 的 ShrinkWrap 变形器

如何解决Maya 的 ShrinkWrap 变形器

我正在尝试在两个 3D 模型上执行 ShrinkWrap 变形器，以便稍后能够执行从一个模型到另一个模型的变形。 当我应用我所做的函数时，当我操纵偏移值或目标通货膨胀时，它不会给我第二个模型的相同形状，它给我一个不完整的不同形状， 这是代码：

RepeatedStratifiedKFold

解决方法

我可以给你我的一段代码来创建一个shrinkWrap，我没有maya所以不能真正检查你的代码：

def getTargetMesh(targetTrans=str):

    sh = cmds.ls(targetTrans,dag=True,shapes=True)
    # Find if at least one of them is an allowable target type
    for s in sh:
        io = cmds.getAttr(s+".io")
        if io:
            continue

        mtype = cmds.nodeType(s)
        if mtype == "mesh":
            return s
    return None

def shrinkWrap(mesh,target,**kwargs):

    targetMesh = getTargetMesh(target) # find a not intermediate shape

    # Find all the surf transforms that have been selected
    surf = cmds.listRelatives(mesh,path=True)

    surface = surf[0]
    
    # SET A BUNCH OF ATTRIBUTES WITH KWARGS or with default value    
    projection = kwargs.get('projection') or 0
    closestIfNoIntersection = kwargs.get('closestIfNoIntersection') or 0
    reverse = kwargs.get('reverse') or 0
    bidirectional = kwargs.get('bidirectional') or 0
    boundingBoxCenter = kwargs.get('boundingBoxCenter') or 1
    axisReference = kwargs.get('axisReference') or 0
    alongX = kwargs.get('alongX') or 0
    alongY = kwargs.get('alongY') or 0
    alongZ = kwargs.get('alongZ') or 0
    offset = kwargs.get('offset') or 0
    targetInflation = kwargs.get('targetInflation') or 0

    shrinkwrapNode = cmds.deformer(surface,type='shrinkWrap')[0]

    cmds.setAttr(shrinkwrapNode + ".projection",projection)
    cmds.setAttr(shrinkwrapNode + ".closestIfNoIntersection",closestIfNoIntersection)
    cmds.setAttr(shrinkwrapNode + ".reverse",reverse)
    cmds.setAttr(shrinkwrapNode + ".bidirectional",bidirectional)
    cmds.setAttr(shrinkwrapNode + ".boundingBoxCenter",boundingBoxCenter)
    cmds.setAttr(shrinkwrapNode + ".axisReference",axisReference)
    cmds.setAttr(shrinkwrapNode + ".alongX",alongX)
    cmds.setAttr(shrinkwrapNode + ".alongY",alongY)
    cmds.setAttr(shrinkwrapNode + ".alongZ",alongZ)
    cmds.setAttr(shrinkwrapNode + ".offset",offset)
    cmds.setAttr(shrinkwrapNode + ".targetInflation",targetInflation)

    # Add the target object
    #
    cmds.connectAttr(targetMesh + ".w",shrinkwrapNode + ".tgt")
    # connect up the smooth target attributes
    # so the smoothed target follows the target shape's settings
    #
    cmds.connectAttr(targetMesh + ".co",shrinkwrapNode + ".co")
    cmds.connectAttr(targetMesh + ".suv",shrinkwrapNode + ".suv")
    cmds.connectAttr(targetMesh + ".kb",shrinkwrapNode + ".kb")
    cmds.connectAttr(targetMesh + ".bnr",shrinkwrapNode + ".bnr")
    cmds.connectAttr(targetMesh + ".khe",shrinkwrapNode + ".khe")
    cmds.connectAttr(targetMesh + ".peh",shrinkwrapNode + ".peh")
    cmds.connectAttr(targetMesh + ".kmb",shrinkwrapNode + ".kmb")

    cmds.select(clear=True)
    return shrinkwrapNode

这是一个函数，我用它来输出一个只有四边形的球体

def createSquareSphere(res=4):
    cub = cmds.polyCube(n = 'qSphere#')
    v = round(sqrt(pow(4,res)))*2
    sph = cmds.polySphere(n = 'proj_tmp',sa=v,sh=v)
    cmds.polySmooth(cub,dv = 4,mth = 0,sdt = 2,ovb = 1,ofb = 3,ofc = 0,ost = 0,ocr = 0,bnr = 1,c = 1,kb = 1,ksb = 1,khe = 0,kt = 1,kmb = 1,suv = 1,peh = 0,sl = 1,dpe = 1,ps = 0.1,ro = 1,ch = 1)
    shWrp = shrinkWrap(cub[0],sph[0],projection = 3,reverse = 1)
    cmds.delete(cub,ch = True)
    cmds.delete(sph)
    return cub[0]
