The base surface is 10,000 units in length and 672 units in height. In order to achieve the appropriate curve interval within this asymmetrical surface geometry, 3 additional support curves were placed at .25, .50, and .75 ratios longitudinally. Splines bridge the five support curves and are projected (via the Y-axis, NOT normal to the surface) onto the base surface. The ideal density, aesthetically speaking, is 14 curves.
The unit is constructed from four input points from which a series of offset planes are constructed. The surfaces are all triangular and can be unrolled without geometric issue, while also allowing highly flexible transformation. I'm working on driving all of these transformations through multiple different attractor points, and will see a complex gradation develop over the entire surface. Below is an example of the part's instantiation, plus a range of geometric transformations it may have.
