Detailed Description

create 2D image data from a 3D spline

build a 3D volume from samples of the RGB colour space build a spline over it and extract a 2D slice

Here we use a quick shot solution. Oftentimes all it takes is a single run of an interpolation with as little programming effort as possible, never mind the performance. Again we use a b-spline with double-precision voxels as value_type, but instead of using vspline::transform, we simply run the calculations in loops.

compile with: clang++ -std=c++11 -o slice3 -O3 -pthread slice3.cc -lvigraimpex g++ also works.
