SCRIPTING THE MODEL IN GRASSHOPPER

The geometry operates in two segments, the triangular lines to squeeze the stoma and the longitudinal part to support the movement. When the motion starts, all the alternate creases move up with the simultaneous contraction of all the creases. 

Parameters used :

-'Vector deconstruction' to achieve a double axial movement

-'Loft' to create surfaces between the creases

-'Move' for the vector movement

-'Addition' 'Subtraction' and 'Multiplication' to achieve a single trigger point
