Rhino and Grasshopper

Spring 2020

4.022 Design Technologies 

  • Incorporate drift into exact pen plotter machine

  • Used Grasshopper to create attractor point and boolean curve script

  • Experimented with brush pens to recreate watercolor effect using wet on wet technique

Phase 2

  • Scaled up with calligraphy brush to apply water 

  • Color study with more complex color interactions in watercolor effect

  • Through experimentation, figured out watercolor effect happens when the brush collect pigment and then lifts up, releasing the pigment through the water trail it just traced.

  • The following iterations all use this method of tracing and lifting.
