The use of high-dynamic-range imaging (HDRI) in computer graphics was introduced by Greg Ward in 1985 with his open-source Radiance rendering and lighting simulation software which created the first file format to retain a high-dynamic-range image. HDRI languished for more than a decade, held back by limited computing power, storage, and ...
Incidentally, this also makes the objects completely transparent when the viewpoint camera is located inside them, because then all the surfaces of the object are facing away from the camera and are culled by the renderer. To prevent this the object must be set as double-sided (i.e. no back-face culling is done) or have separate inside surfaces.
The guiding vision for the metamaterial cloak is a device that directs the flow of light smoothly around an object, like water flowing past a rock in a stream, without reflection, rendering the object invisible. In reality, the simple cloaking devices of the present are imperfect, and have limitations.

An object in this state is said to be invisible (literally, "not visible"). The phenomenon is studied by physics and perceptual psychology . Since objects can be seen by light from a source reflecting off their surfaces and hitting the viewer's eyes , the most natural form of invisibility (whether real or fictional) is an object that neither ...
