The mode l ing o f complex geometry o f ten cha l lenges means o f representat ion that revea l moments o f tempora l i t y and morpho logy . For the f i rs t excers ise in both sc ient i f i c exp lorat ion and prob lem so lv ing w i th in the d ig i ta l wor ld we where asked to represent the st i l l ness o f a b looming f lower . F lora l taxonomy was the in i t ia l s tep in understand ing the geometry beh ind the unfo ld ing o f the peta ls . Documentat ion o f the process became a very important in i t ia l s tep in the construct ion o f the var ious layers o f fo lds .

Before I began deve lop ing a d ig i ta l a lgor i thm, my exp lorat ion focused on research ing ex is t ing mode ls that cou ld in form me o f a new approach to th is sub ject . By cons is tent l y test ing smal ler fo lds o f r ig id or igami mode ls , I t Was d i f f i cu l t to fo ld the pat tern when the sheet reached i t max imum curvature (complete l y fo lded) . A f ter rev iew ing a ser ies o f d ig i ta l a lgor i thm prov ided by brave or igami fo lders be fore me, i became fami l i ar w i th the poss ib i l i t i es and l im i tat ion o f or igami fo ld ing w i th in the fo l low ing computer a ided programs ; Rh inoceros , Grasshopper , kangaroo , and Karamba. Rh inoceros , as a lways is the v isua l output o f a ser ies o f p lug - ins runn ing through grasshopper and other a lgor i thmic eng ines . Kangaroo ; as a phys ics eng ine , and Karamba for s tructura l ana l ys is . These d i f ferent p lug - ins were a b ig he lp in answer ing many o f the unpract iced quest ions . The or igami de f in i t ion that i ended up exp lor ing began w i th the idea o f a tube or a down spout and eventua l l y morphed i tse l f w i th the idea o f a meander ing r i ver . The a im was to exp lore how d isrupt ion o f f low cou ld occur thru these or igami p ieces . I a lso took on the cha l lenge o f incorporat ing Ga lapagos in to the de f in i t ion . Ga lapagos as i found i t a new means o f br idg ing the gap between parametr ic des ign and evo lut ionary comput ing . The purpose was to popu late a ser ies o f the meander ing gut ters base on a ser ies o f parameters w i th the means be ing the vo lume o f the system s imp ly ca lcu lated by d i v id ing the area o f the or igami by the vo lume.

Reverse Eng ineer ing as a geometr ic mode l ing too l a l lows us to exp lore ex is t ing phys ica l mode ls that have no h is tor ica l drawings or documentat ions .3D Scanners a l low for such process to ex is t leverag ing the ro le o f Reverse Eng ineer ing as an acces ib le too l for des ign . F i rst , the scanner generates a 3D mode l o f the part , then , i t uses spec ia l i zed app l icat ions to generate a d ig i ta l po int c loud based on an ex is t ing po l ygona l gr id . So f tware that comes supp l ied w i th the scanner fac i l i ta te the transfer f rom po int c louds to 3D mode ls through a number o f w ide l y used formats , wh ich makes i t cons iderab l y eas ier to t ransfer data between app l icat ions . The chosen ob ject to be scanned for th is ass ignment was a Sh i i take Mushroom measur ing approx imat l y 2 inches in length . we chose to scan at h igh f ide l i t y in hope o f caputr ing as much deta i l as poss ib le f rom the sample at hand . Unfortunat ley do ing so resu l ted in a very large and h igh l y dense mesh that made i t imposs ib le to reduce the mesh w i thout loos ing peaces o f the geometry . With the t ime f rame for th is ass ignment we at tempted to work w i th the mesh as is , operat ing on i t w i th a ser ies o f Rh ino scr ipt commands that ut i l i ze concepts o f anamorph ic pro ject ion exp lored ear l ier in the course a l low ing us to a l ter the phys ica l mesh o f the scanned sh i i take mushroom. The resu l t was h igh l y organ ic in nature and very in terest ing in compar ison to i ts natura l geometry .

1 .This is a good mesh.

Importants thing to consider with this mesh: Mesh has 5949 naked edges. Although this does not necessarily mean that the mesh is bad, naked edges can cause problems if the ultimate goal is STL output.

General information about this mesh: Mesh does not have any degenerate faces. Mesh does not have any zero length edges. Mesh does not have any non manifold edges. Mesh does not have any duplicate faces. Mesh does not have any faces that could make it better if their directions were flipped. Mesh does not have any disjoint pieces. Mesh does not have any unused vertices.
