OpenMayaで選択中のオブジェクトのComponent IDsやPoly Countを取得する逆引きのようなものです
import maya.OpenMaya as OpenMaya #get mSelection List SelectionList = OpenMaya.MSelectionList() OpenMaya.MGlobal.getActiveSelectionList(SelectionList) #MItSelectionList iteritor for meshes #filter with mfn class iterMesh = OpenMaya.MItSelectionList(SelectionList, OpenMaya.MFn.kGeometric) # selection iterator while not iterMesh.isDone(): polyList = [] dagPath = OpenMaya.MDagPath() iterMesh.getDagPath(dagPath) fnMesh = OpenMaya.MFnMesh(dagPath) # print num information about polycount, vertecescount and etc.... meshNumPolygons = fnMesh.numPolygons() print "fnMesh.numPolygons: %s" % meshNumPolygons meshNumVertices = fnMesh.numVertices() print "fnMesh.numVertices: %s" % meshNumVertices meshNumEdges = fnMesh.numEdges() print "fnMesh.numEdges: %s" % meshNumEdges meshNumUVs = fnMesh.numUVs() print "fnMesh.numUVs: %s" % meshNumUVs meshNumFaceVertices = fnMesh.numFaceVertices() print "fnMesh.numFaceVertices: %s" % meshNumFaceVertices meshNumUVSets = fnMesh.numUVSets() print "fnMesh.meshNumUVSets: %s" % meshNumUVSets numColors = fnMesh.numColors() print "fnMesh.numColors: %s" % numColors meshNumColorSets = fnMesh.numColorSets() print "fnMesh.meshNumColorSets: %s" % meshNumColorSets numNormals = fnMesh.numNormals() print "fnMesh.numNormals: %s" % numNormals iterMesh.next()
