Tumour Tracking (Visualisation)

You will be given a huge data sets of 3D data points (x,y,z) to deal with. The data will be in a cycle format (repeatition) and you need to visualize these data points and draw a curve(thin\light) tracing the points. These curves resembles a spring roll. After that, a final curve have to be extracted from the points using the method of approximation. The final curve have to be highlighted as the path of the tumour. The final curve is obtained from the concept of B-spline curve.
