Concentration of light, especially sunlight, can burn. The word caustic, in fact, comes from the Greek καυστός, burnt, via the Latin causticus, burning. A common situation where caustics are visible is when light shines on a drinking glass. The glass casts a shadow, but also produces a curved region of bright light.
Reflective caustic generated from a circle and parallel rays. On one side, each point is contained in three light rays; on the other side, each point is contained in one light ray. In differential geometry, a caustic is the envelope of rays either reflected or refracted by a manifold. It is related to the concept of caustics in geometric optics ...
Lens flare on Borobudur stairs to enhance the sense of ascending. A lens flare is often deliberately used to invoke a sense of drama. A lens flare is also useful when added to an artificial or modified image composition because it adds a sense of realism, implying that the image is an un-edited original photograph of a "real life" scene.
The considerations made in the previous section give a proof that the caustic of a circle with light source on the perimeter of the circle is a cardioid. If in the plane there is a light source at a point on the perimeter of a circle which is reflecting any ray, then the reflected rays within the circle are tangents of a cardioid.
Light has to pass through a larger part of the atmosphere when the sun is lower on the horizon. Red, orange and yellow have longer wavelengths, which means, in short, they have a better chance of ...

Diffuse interreflection is apparent when light from one diffuse object is reflected onto another. Photon mapping is particularly adept at handling this effect because the algorithm reflects photons from one surface to another based on that surface's bidirectional reflectance distribution function (BRDF), and thus light from one object striking another is a natural result of the method.
As you likely know by now, Travis Kelce will be vying for his fourth Super Bowl win with the Kansas City Chiefs on February 9. You’re probably also aware that he’s dating 14-time Grammy winner ...
