THE DESIGN METHODOLOGY OF THIS WORKSHOP IS DEPENDENT UPON A CONTINUOUS STUDY OF MATERIAL BEHAVIOUR THROUGH DEVELOPING STITCHING PATTERNS IN LYCRA AND CASTING THEM IN PLASTER. CURVATURE TYPOLOGY FOCUSES ON THE INVESTIGATION OF MORPHING A LINE /2D PLANE TO A CURVE / 3D SURFACE THROUGH THE PATTERN APPLIED TO THE FABRIC IN CONJUNCTION WITH GRAVITATIONAL FORCES DURING THE CASTING PROCES. THE INVESTIGATION FOCUSED ON DEVELOPING A SUITABLE PATTERN WHICH WOULD FUNCTION STRUCTURALLY ONCE CASTED WITH PLASTER. THE PARAMETERS SET BY THE PATTERN ALLOWED US TO CONTROL THE FLOW OF PLASTER AND UNDERSTAND THE RESISTANCE AND DEFORMATION OF THE MATERIALS. THE TEAM CONDUCTED FIVE EXPLORATIONS OF CURVATURE, STARTING WITH UNDERSTANDING THE POINTS OF INFLECTION THAT FORM A SIMPLE TWO-DIMENSIONAL CURVE AND FINALIZING WITH POINTS OF TORSION THAT BEGIN TO TRANSORM A CURVE INTO THREE-DIMENSIONAL SPACE.

CURVATURE THROUGH PATTERN

[7]


CORN FOCUSED ON GETTING ACQUAINTED WITH THE TECHINIQUE OF CREATING FOLD STITCHES IN THE FABRIC IN ORDER TO CREATE AN INTERDEPENDENT RELATIONSHIP BETWEEN THE INFLECTION POINTS IN A CURVE AND THE PLASTER BEHAVIOUAR . IN THIS CASE, THE UNIFORM FOLDS PRODUCED A UNIFROM CURVE WITH VERY LITTLE WEAK POINTS ALONG THE CAST.

CURVATURE CONTROL

[15]


GARLIC FOCUSED ON UNDERSTADING THE SCALEABILITY OF THE PATTERN IN ORDER TO CREATE A SELF-STANDING CAST. THE PATTERN DEVELOPED IN THIS INSTANCE IS A GRADIENT OF SIZE FOLDS IN X-Y AXES, ALLOWING FOR MORE ARTICULATED CURVATURE AFTER CASTING.

CURVATURE PARAMETRIZATION

[23]


BANANA TREE FOCUSES ON THE PARAMETRIZATION OF THE CURVATURE IN THE CAST. EACH SECTION OF THE PATERN IS DEVELOPED TO CONTROL THE AMOUNT OF INFLECTION POINTS IN THE CURVATURE, THUS THE CAST IS ABLE TO SHIFT BETWEEN DIFFERENT CURVE PROFILES.
