This is the applet we used to create the 3d printed cell cycle pieces. It uses the same technique as the radiolaria applet, but in 3D. It also employs Catmull-Clark subdivision surfaces to make the smoothed shape.

To create the radiolaria line, we used a particle system to simulate a hexagonal mesh of springs. A particle system is a physics simulator which works with point particles and forces. You can do a surprisingly large amount without thinking about rigid bodies. The applet allows you to play with the same system we used to create the radiolaria line and make patterns by distorting the mesh.

The applet currently has five tools for distorting the mesh. There are tools for creating and deleting attractive and repulsive forces, and there are tools for cutting and healing springs.

Radiolaria are microscopic organisms that exhibit beautiful structures often featuring hexagonal patterns.

In this applet we experiment with an algorithm called diffusion limited aggregation or DLA which models dendritic growth. DLA simulates the movement of particles undergoing random motion, and when particles collide they stick. Over time the particles aggregate into organic, branching forms similar to those seen in corals and dendritic crystals.

When playing with the applet, you can access various parameters through the control panels and use them to change the overall form of the aggregation.

Designs you create using the applet can be ordered as custom, one of a kind jewelry.
