Incusion

Incusion, is an architectural technique with political potential, can be understood as a method for describing with a present form a figure that is absent, as a singular shape that results from the intersection of multiple geometries, as the removal of one geometry from another, or as the impression left on one by the other.

The Incusion form-finding research started by using two plastic Bartlett pears intersecting one another in space and by manually constructing a physical model of the intersection curves using Boolean union operation. The plastic pear was then subdivided to calculate the coordinates of the floating points that define the fruit surface to be transferred into a NURBS modeling software to precisely generate a three-dimensional digital replica.

Then a custom script was created with specific algorithms allowing the digital model to be arrayed, scaled, rotated and intersected one another following specific set of rules. Another script was then prepared to calculate the mathematical equations of the intersection curves. Finally, a high-resolution mesh was prepared from the incused geometry and was 3D printed and later was cast in polyurethane resin for a final durable physical model.
