Radioluminescent paint is a self-luminous paint that consists of a small amount of a radioactive isotope (radionuclide) mixed with a radioluminescent phosphor chemical. The radioisotope continually decays, emitting radiation particles which strike molecules of the phosphor, exciting them to emit visible light.
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...
Effects that may need to be simulated include: Shadows, including both shadows with sharp edges and soft shadows with umbra and penumbra; Reflections in mirrors and smooth surfaces, as well as rough or rippled reflective surfaces; Refraction – the bending of light when it crosses a boundary between two transparent materials such as air and ...
Glow sticks also serve multiple functions as toys, readily visible night-time warnings to motorists, and luminous markings that enable parents to keep track of their children. Another use is for balloon-carried light effects. Glow sticks are also used to create special effects in low light photography and film. [14]

Being transparent and durable, PMMA is a versatile material and has been used in a wide range of fields and applications such as rear-lights and instrument clusters for vehicles, appliances, and lenses for glasses.
Animation is a filmmaking technique whereby still images are manipulated to create moving images.In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film.
The use of the gobo is "subtractive", as opposed to using a "reflector" to bounce added light into a shadow (thus "additive" lighting). Use of a gobo subtracts light from a portion of an overall shaded subject and creates a contrast between one side of the subject and the other.
