there's really no need to get the points on both meshes, and depending on
vertex counts, you may wanna avoid getting all the vertices opposed to just the
ones you have selected.
It would be strange to loop over the full set of points on the target mesh,
updating just the indices of the selected vertices on the src mesh, then
setting ALL the points on the tgt. you can do it, but its strange imo.
But anyways, The code below doesn't store any vertices/MPoints. It simply
loops over the indices of the vertices you have selected on the src mesh, and
sets the point on the tgt mesh with the equivalent point on the src mesh in
local space.
import maya.api.OpenMaya as om2
# get MSelectionList of actively selected objects in the viewport
sel = om2.MGlobal.getActiveSelectionList()
# the first item is the src, along with its selected vertices
src, components = sel.getComponent(0)
# the second selected item is the target
tgt = sel.getDagPath(1)
# create function sets
fnMeshSrc = om2.MFnMesh(src)
fnMeshTgt = om2.MFnMesh(tgt)
fnSingle = om2.MFnSingleIndexedComponent(components)
indices = fnSingle.getElements()
for index in indices:
fnMeshTgt.setPoint(index, fnMeshSrc.getPoint(index, om2.MSpace.kObject),
om2.MSpace.kObject)
It may be better to get the entire point array of the src mesh, and index into
that instead of calling 'getPoint()' inside the loop. It depends on object
vertex counts, and how many vertices you have selected. you'll have to test it.
srcPnts = fnMeshSrc.getPoints(om2.MSpace.kObject)
indices = fnSingle.getElements()
for index in indices:
fnMeshTgt.setPoint(index, srcPnts[index], om2.MSpace.kObject)
goodluck!
