The "current" geometry is just a weighted average of the vertex
positions of the input geometries - so if there are n geometries in the
morph, each with m vertices, vertex i of the net geometry would be
do i=1,m
vnet(i) = w1*v1(i) + w2*v2(i) + ... + wn*vn(i)
enddo
Where w1 thru wn are the weights at the given moment, which must sum to
1.0 (i.e. w1 + w2 + ... + wn = 1.0)
So, if you have the specified geometries and the weights, you can get
the Point3ds at the vertices and do the sum yourself to get the net
geometry.
Hope this helps,
Matt

hi. yes it looks like you need the algorythm. i have no idea how
complicated that is.
i cant remember if i have seen one some where or not in the past, if
i have i forgot
were it was.
sorry cant help.
