The value of x should be between 0.0 and 1.0. This done by interpolating between the vertices of the individual shapes. Thus, normal and polygon information remains the same. This functions creates the drawing lists for the turbulated cube. This function generates the actual drawing lists based on the array on points.
Index is the number of the drawing list.
All cubes will have the same polygons and normals may be computed too. The actua l amount of displacement for individual points will vary.
