A visual article and novel web path tracer for opal as a natural photonic crystal. The project follows silica sphere packing, lattice planes, Bragg diffraction, and spectral rendering.

Selected work
Vector fields rendered as arrows, particles, and trails, using procedural tube meshes and real-time field integration. The lens lets you place sources and watch the field lines they generate evolve around them in space.
The lens introduces matrices through their rows and columns, along with the operations that act on them, including multiplication and elimination. It also gives visual explanations for topics such as rotations and eigenvalues.
