To find (and change) the 16 | Processing sketchbook location on your computer, open the Preferences window 17 | from the Processing application (PDE) and look for the "Sketchbook location" 18 | item at the top. 19 | 20 | Copy the contributed library's folder into the "libraries" folder at this 21 | location. You will need to create the "libraries" folder if this is your first 22 | contributed library. 23 | 24 | By default the following locations are used for your sketchbook folder: 25 | For Mac users, the sketchbook folder is located inside ~/Documents/Processing. 26 | For Windows users, the sketchbook folder is located inside 27 | 'My Documents'/Processing. 28 | 29 | The folder structure for library ComputationalGeometry should be as follows: 30 | 31 | Processing 32 | libraries 33 | ComputationalGeometry 34 | examples 35 | library 36 | ComputationalGeometry.jar 37 | reference 38 | src 39 | 40 | Some folders like "examples" or "src" might be missing.

ComputationalGeometry

43 |

44 | A library by Mark Collins & Toru Hasegawa for the Processing programming environment.
45 | Last update, 07/23/2013. 46 |

47 |

48 | A simple, lightweight library for generating meshes such as isometric surfaces, boundary hulls and skeletons.
49 | Meshes are generated by specifying points and edges that inform the generation of the target output. In isometric surfacing, the library supports direct manipulation of the underlying grid data as well as simple meta-ball modeling.
50 | Feel free to replace this paragraph with a description of the library.
51 | Contributed libraries are developed, documented, and maintained by members of the Processing community. Further directions are included with each library. For feedback and support, please post to the Discourse. We strongly encourage all libraries to be open source, but not all of them are. 52 |

If a library isn't there, 9 | it will need to be installed manually by following the instructions below. 10 | 11 | 12 | Manual Install 13 | 14 | Contributed libraries may be downloaded separately and manually placed within 15 | the "libraries" folder of your Processing sketchbook. To find (and change) the 16 | Processing sketchbook location on your computer, open the Preferences window 17 | from the Processing application (PDE) and look for the "Sketchbook location" 18 | item at the top. 19 | 20 | Copy the contributed library's folder into the "libraries" folder at this 21 | location. You will need to create the "libraries" folder if this is your first 22 | contributed library. 23 | 24 | By default the following locations are used for your sketchbook folder: 25 | For Mac users, the sketchbook folder is located inside ~/Documents/Processing. 26 | For Windows users, the sketchbook folder is located inside 27 | 'My Documents'/Processing. 28 | 29 | The folder structure for library ComputationalGeometry should be as follows: 30 | 31 | Processing 32 | libraries 33 | ComputationalGeometry 34 | examples 35 | library 36 | ComputationalGeometry.jar 37 | reference 38 | src 39 | 40 | Some folders like "examples" or "src" might be missing.

ComputationalGeometry

43 |

44 | A library by Mark Collins & Toru Hasegawa for the Processing programming environment.
45 | Last update, 07/25/2013. 46 |

47 |

48 | A simple, lightweight library for generating meshes such as isometric surfaces, boundary hulls and skeletons.
49 | Meshes are generated by specifying points and edges that inform the generation of the target output. In isometric surfacing, the library supports direct manipulation of the underlying grid data as well as simple meta-ball modeling.
50 | Feel free to replace this paragraph with a description of the library.
51 | Contributed libraries are developed, documented, and maintained by members of the Processing community. Further directions are included with each library. For feedback and support, please post to the Discourse. We strongly encourage all libraries to be open source, but not all of them are. 52 |

If a Library isn't there, it will need to be installed manually by following the instructions below. 8 | 9 | ### Manual Install 10 | 11 | Contributed Libraries may be downloaded separately and manually placed within the `libraries` folder of your Processing sketchbook. To find (and change) the Processing sketchbook location on your computer, open the Preferences window from the Processing application (PDE) and look for the "Sketchbook location" item at the top. 12 | 13 | By default the following locations are used for your sketchbook folder: 14 | * For Mac users, the sketchbook folder is located inside `~/Documents/Processing` 15 | * For Windows users, the sketchbook folder is located inside `My Documents/Processing` 16 | 17 | Download Computational Geometry from http://thecloudlab.org/processing/library.html 18 | 19 | Unzip and copy the contributed Library's folder into the `libraries` folder in the Processing sketchbook. You will need to create this `libraries` folder if it does not exist. 20 | 21 | The folder structure for Library Computational Geometry should be as follows: 22 | 23 | ``` 24 | Processing 25 | libraries 26 | Computational Geometry 27 | examples 28 | library 29 | Computational Geometry.jar 30 | reference 31 | src 32 | ``` 33 | 34 | Some folders like `examples` or `src` might be missing. After Library Computational Geometry has been successfully installed, restart the Processing application. 35 | 36 | ### Troubleshooting 37 | 38 | If you're having trouble, have a look at the [Processing Wiki](https://github.com/processing/processing/wiki/How-to-Install-a-Contributed-Library) for more information, or contact the author [Mark Collins & Toru Hasegawa](http://thecloudlab.org). 39 | -------------------------------------------------------------------------------- /distribution/ComputationalGeometry-3/download/ComputationalGeometry-3.txt: -------------------------------------------------------------------------------- 1 | # More on this file here: https://github.com/processing/processing/wiki/Library-Basics 2 | # UTF-8 supported. 3 | 4 | # The name of your Library as you want it formatted. 5 | name = Computational Geometry 6 | 7 | # List of authors.

Computational Geometry

43 |

44 | A Library by Mark Collins & Toru Hasegawa for the Processing programming environment.
45 | Last update, 02/10/2016. 46 |

47 |

48 | A simple, lightweight library for generating meshes such as isometric surfaces, boundary hulls and skeletons.
49 | Meshes are generated by specifying points and edges that inform the generation of the target output. In isometric surfacing, the library supports direct manipulation of the underlying grid data as well as simple meta-ball modeling.
50 | Feel free to replace this paragraph with a description of the Library.
51 | Contributed Libraries are developed, documented, and maintained by members of the Processing community. Further directions are included with each Library. For feedback and support, please post to the Discourse. We strongly encourage all Libraries to be open source, but not all of them are. 52 |
