The generation of photo-real renderings of bioluminescence is developed for creatures from the abyss.
Bioluminescence results from a chemical reaction with examples found in deep-sea marine environments including:
algae, copepods, jellyfish, squid, and fish. In bioluminescence, the excitation energy is supplied by a chemical reaction,
not by a source of light. The greatest transparency window in seawater is in the blue region of the visible spectrum.
From small creatures like single-cell algae, to large species of siphonophore Praya dubia (40m), luminescent
phenomena can be produced by mechanical excitement from disturbances of objects passing by. Deep sea fish, like the
Pacific Black Dragonfish are covered with photophores along the upper and lower surfaces which emits light when
disturbed. Other animals like small squids have several different types of light organs oscillating at different rates.
Custom shaders and material phenomena incorporate indirect lighting like: global illumination, final gathering, ambient
occlusion and subsurface scattering to provide photo real images. Species like the Hydomedusae jellyfish, produce
colors that are also generated by iridescence of thin tissues. The modeling and rendering of these tissues requires thin
film multilayer stacks. These phenomena are simulated by semi-rigid body dynamics in a procedural animation
environment. These techniques have been applied to develop spectral rendering of scenes outside the normal visible
window in typical computer animation render engines.
