    Painting with light

Session/Category Title:   Manifesting Art



    This sketch presents fractal art work created by ray tracing the specular highlights of point lights on the inside surface of a hollow sphere. The sphere has a mirror surface on the inside that contributes no colour to the images, but there is spread in the local specular reflection. The resulting images consist entirely of specular highlights and their reflections. I call this painting with light because, although recursive ray tracing is used, no objects are visible.
