In this post I will show you a project where I have spent some hours for several months.
This project has helped me as case study of OpenGL and its integration with the library toxiclibs. The version used is 1.5.1 processing, and of course all access to Opengl I have realized through GLGraphics.
I have also used flocking algorithms offered by Daniel Shiffman integrating with perlin noise.
For the generation of the trees I started from a wonderful example of openprocessing

Hope you enjoy.
