[Insight-users] surface textures?

[Luis Ibanez]

Hi Markus,

Overlapping points may not be a good idea if you want
to parameterize a 2D  manifold.

What the Kernel Splines do is to have two sets of
landmarks. One set is termed the 'source' while the
othere is the 'target'. Both have the same number of
point, and they are associated one by one.

The Kernel spline take the vectors describing the
relative positions of corresponding landmarks and
interpolate such vectors over the space.

You are encouraged to build the ThinPlate application,
Some minutes playing with it will give you a clear
perception of what can be done with this kernel based
interpolators.

If you are more familiar with VTK, there is an equivalent
class contributed by David Gobi.


Regards,


     Luis
