HADES: Embrace constraints - help to focus decisions around pivot points whenn u see all all the time there is no suspension - constraints can pass of content

human is good with reco patterns

  • so proceduralism can be a trap

Procedural Approach

  • scalability
  • prone to human error
  • parametric

Patterns

Spiral

  • (flowers, golden spiral)

Branching

  • (foliage)

Central

  • (star, Rose(tta) window)

Symmetry

Tiles

(polygons with contact) - (pavement) - squares - trix - hex (honeycomb)

Nested

  • (mandalas,)

Penrose tiling

  • (2 polygonal arrows in simple version ) (u can get the illusion of forbidden symmetry i.e. pentagonal (related by golden ratio) don’t repeat… - quasicrystals )

Girih Tiles

Islamic star patterns (one 10-way symmetry and smaller )

Interpretive

equations

  • Computational Geometry - visualization of math equations
  • Interpretive: noise Perlin, grid/cell (voronoi/delaunay), metaballs

Computed

Fractals

Algorithmic Botany

Fractal

  • L-system - recursive turtle commands

Emergent

RNG

Random number generator

Cellular Automata

Game of life - simulation of grid with life/death state https://youtu.be/7-97RhAZhXI
conways / lenia / … Conway and many other methods

Reaction Diffusion

Reaction diffusion - blur/sharpen neighbor. simple (Gray scott formula):

  • seed like noise
  • feedback:
  • blur
  • sharpen
  • do it again (LOOP IT)

https://youtu.be/VBzIPLh-ECg

black and white spaces

  • blur > gaussian blur 2
  • chemical reaction > edge detection: duplicate and blur 4x > subtract.
