summary The idea of an emergent or generative form based on repeating rules of development borrowed from the field of developmental biology has provided fertile ground for inspiration for architectural theory and computational design. With simple constraints developed iteratively, complex geometry and form generation can be distilled down to a list of developmental rules or functions in order to deterministically generate form. The ideas and illustrations of naturalists on organic form and developmental biology leading back to the turn of the 20th c., such as the work of D'arcy Wentworth Thompson and Ernst Haeckel, have inspired architects from Louis Sullivan all the way to contemporary generative design. This study revisits this design tradition of biomimetic geometries based on deterministic rules for the iterative development of forms based on biological analogs and models for growth. A series of semi-regular compound patterns were developed using parametric modeling and iterative rules. These geometries were then applied to surface topologies as a decorative tactile embellishment resulting in complex thermodynamic conditions. A series of physical prototypes where then developed with different high-relief patterns and pattern densities. Positive prototype geometries were then produced using stereolithography for casting plaster molds for the production molding of finished ceramic pieces for thermal analysis using digital thermography. By studying the performance of these complex geometries as physical prototypes under controlled experimentation, high-relief surfaces and the resulting thermodynamic conditions can be understood not just qualitative experience, but also quantitatively through measured performance metrics and innovative tools for analytical analysis.
