CGAL users discussion list

Hi,
I have a vtk file for a scalar variable in 3D (vtk DataFile Version 2.0,
DATASET UNSTRUCTURED_GRID,  Points (coordinates), Cells (vertex indexes),
cell type, point or cell scalar data) and I'm wondering how I can use
these information to create a labeled 3D image to mesh with the 3D
mesh-generation package.
I started resampling my data by means of Visit in order to obtain a
uniform grid, then I tried to use the function:
 bool
Image_3::read_vtk_image_data(vtkImageData* vtk_image (in Image_3.cpp in
CGAL).
I enabled it with cmake -DWITH_VTK:BOOL=TRUE in Cmake Cache, but it
doesn't work and the function is not considered member of the class Image,
where I'm wrong?
Could anyone help me?
Thanks en advance!
