Abstract: Weave is a process for fabrication of freeform shells, proceeding from a formal definition of desired final shape(s), to an optimized parametric mesh of said shape(s), to physical battens which, once fastened at calculated crossings, realize the final object of use. This initially iso-parametric mesh is triangulated for self-shaping and rigidity, and optionally spiralized for economy, integrity of raw material, and surface smoothness The mesh's density and topology is controlled by Weave such that the constructed object automatically takes on, as it is fastened, the shape and dimensions of the designed fabrication without explicit registration, alignment or ambiguity. Essential is the precise adjustment of batten length between intersections to accomodate interweaving. Weave's calculations also accomodate all other necessary geometrical and material factors. Weave does not constrain shape type, complexity, scale or material.
