Hi Nick
It seems you have a linking problem so it might be that one cmake line misses some libraries.
Here is my CMakeLists.txt:
====================================================
cmake_minimum_required(VERSION 2.8)
PROJECT( test-regult-itk-bspline )
FIND_PACKAGE(VTK REQUIRED)
INCLUDE(${VTK_USE_FILE})
FIND_PACKAGE(ITK REQUIRED)
INCLUDE(${ITK_USE_FILE})
ADD_EXECUTABLE(testRegulItkBspline testRegulItkBspline.cxx)
TARGET_LINK_LIBRARIES (testRegulItkBspline ${ITK_LIBRARIES} ${VTK_LIBRARIES})
====================================================
I am using VTK 5.8 and ITK 4.2.
Thanks a lot for trying to compile this.

Hi Mathieu,
I'm having some difficulty compiling your code (see below).
Considering the errors, I'm wondering if I'm compiling against the right version of VTK. Also, what version of ITK are you using?

But it seems to be moving only at the first time point. Maybe I incorrectly defined the temporal span of the transformation ....

So if I have a 20x20 control point grid defining a b-spline object over a domain of 100mm x 100mm, there are many ways I can define the domain which won't matter for the internal calculations of the final "PhiLattice".

> In the B-spline classes that I've written (including a rewrite of the B-spline transform class), I don't make a distinction between the internal control points and the border control points. When you specify the parametric domain for the BSplineScattered...Filter (by specifying the origin, size, and spacing), the control points get laid out automatically based on that domain and the spline order(s) including the border ones.
