Have you read up on the MFloatPoint in the docs? It shouldn't be too confusing to use. http://help.autodesk.com/view/MAYAUL/2016/ENU/?guid=__cpp_ref_class_m_float_point_html
Assuming your verts are normal tuples and you want to convert them to MFloatPoint, import maya.OpenMaya as om def findDiff(scan1_verts, scan2_verts): diff_list = om.MFloatPointArray() for v1, v2 in zip(scan2_verts, scan1_verts): p1 = om.MFloatPoint(*v1) p2 = om.MFloatPoint(*v2) diff_list.append(om.MFloatPoint(p2 - p1)) return diff_list Justin On Sat, Dec 10, 2016 at 3:47 AM <s...@weacceptyou.com> wrote: hello i have some python code that subtracts corresponding coordinates from two separate lists and then appends the result to a new list: def findDiff(scan1_verts, scan2_verts): diff_list=[] for (v1,v2) in zip(scan2_verts,scan1_verts): diff=(v1[0]-v2[0]),(v1[1]-v2[1]),(v1[2]-v2[2]) diff_list.append(diff) return diff_list what i want to know is if this can be done easily with the maya python API. I later want to use setPoints to set the verts of a new piece of mesh with this list. so for that reason i think they need to be OpenMaya.MFloatPoint values or something. sorry im so confused by how the API does things. If someone could show me how to set it up i would really appreciate it. thanks, Sam -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
