Sample procedures for producing DECAY-based forms

Start with an object and remove parts of it through different processes.
Instead of focussing on construction, focus on building a rich language of decomposition.


  1. Erosion (wind, water, gravity – apply forces to remove surface elements)
  2. Shedding (skin, bark, rear-vision mirrors – bits fall off in sheets or whole components become detached)
  3. Oxidation (combustion, rust. Contact between object and some media e.g. air/water & heat cause conversion of surface material into its oxidised state which (i) will have different material properties including (ii) it may be more likely to erode due to unstable bonds with the surface)
  4. Consumption (agents external to the object actively consume or remove parts of it. e.g. burrowing by termites, tearing by crows)
  5. Rot (agents internal or external to the object consume parts of it and destroy its macro-structure, reducing it to basic elements)
  6. Excision (e.g. CSG subtraction, sections of the object are cleanly cut out and removed)
  7. Ringbarking (i.e. stopping flow of nutrients to one part until it dies and is ready to rot)
  8. Pruning (chop off an external component)
  9. Compaction (e.g. dent a surface or crush an object)
  10. Collapse (break internal structural bonds that maintain the shape of the object so that other forces (e.g. skin-tension, gravity) take over determining its shape.
  11. Atrophy (i.e. sections become withered, allowing an underlying (bone?) structure to be perceived and to dictate the form of the surface)

…imagine a dark-grey square consisting of a micro-scale network of lines on a white background. This would be a suitable starting object for the application of all of the above procedures in interactively specified regions.
