Project009 Knowledge Patterns I

The line connecting same ratio points on the top and bottom edge of the surface is projected onto the surface, producing a framework for future overlay. The number of curves is manually controlled to achieve expected density.

 The surface is controlled by boundary line and the passing point

The top and bottom lines can also be isolated from the surface and be controlled separately, creating a potential muli-sections surface. Therefore, the performing curves can be interpreted as the dialog between the the fill surface and the multi-sections surface.
