File:Computer rendering of a wine glass caustic.png

Summary

File information
Description	Computer rendering of a wine glass caustic (volumetric and projected) for incident white light under an angle of 24° relative to the horizontal. The volumetric scattering in "dusty air" appears in this rendering for all light that interacted with the glass or the liquid. The caustic projected in the horizontal is hour-glass-shaped.
