HE_Mesh* is a Java library for creating and manipulating polygonal meshes. Containing no display functionality of its own, it is meant to be used with Processing.

My code quality warnings for the constructs are doubly valid here. HE_Mesh is an after-hours hobby project aggregating years of code snippets and 3rd part libraries. It is by no means production strength, neither in robustness, performance, consistency or maintenance. Consider it a toy, playground, a sandbox that allows me to explore a range of possibilities that I wouldn’t be able to otherwise. Friends** asked me to share this toy, this library.

Since I cannot give you any guarantees or reliable support,  the HE_Mesh library is public domain. Very little in the library is invented by me. The knowledge required to create it is all out there.

If you wish to support the further development of HE_Mesh, or it helped you somehow in a project, you might consider this innocent little Paypal link.

Installation for Processing

Processing documentation: How to Install a Contributed Library

If you want to keep up with the build of the day, manual installation is necessary.

Contributed libraries for Processing are installed inside the libraries subfolder of the sketchbook. If you don’t know where Processing saves your sketches you can check this in the File->Preferences… menu.

Inside the downloaded zip-file is a single directory hemesh with several subfolders . Unzip this folder to the libraries subfolder of your sketchbook. Make sure you retain the entire directory structure.

Always close the Processing IDE and delete your previous hemesh installation before installing a new version.

Setting up a HE_Mesh Processing sketch

This is my minimal framework for a Processing 3 sketch using HE_Mesh.
