control the direction of vectors in more user friendly way using flow lines

[prashant-saxena]

Hello, I am looking for a vector field generation algorithm where the direction of the generated vectors can be controlled in a much simpler way. The closest I have found is this, here vectors are controlled by drawing a flow line. These two videos from the paper clearly demonstrate the feature. video video

I have also tried compiling stripes because of it's ability to control vector field but all I see is a big black bunny. It seems there is a problem with shaders.
