What do you understand by term ray casting? Explain briefly?
Expert
Ray casting is a technique in which the surfaces of objects observable to the camera are found by throwing or casting the rays of light from viewer to the scene. The main idea behind the ray casting is to shoot rays from the eye, one per pixel, and find out the closest object which block the path of that ray – imagine of an image as a screen door, with each and every square in the screen being a pixel.

Uncertainty principle (W. Heisenberg; 1927): A principle, central to the quantum mechanics that states which two complementary parameters (like energy and time, position and momentum, or angular momentum and angular displacement) can’t both be r
Does solar radiation encompass a complete spectrum of all the forms of electromagnetic radiation?
Davisson-Germer experiment (C.J. Davisson, L.H. Germer; 1927): The experiment which conclusively proved the wave nature of electrons; diffraction patterns were examined by an electron beam penetrating into the nickel target.
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
Einstein-Podolsky-Rosen effect: EPR effect: Consider the subsequent quantum mechanical thought-experiment: Take a particle that is at rest and has spun zero (0). This spontaneously decays into two fermions (spin 1/2 particles), that stream away in the
Landauer's principle: The principle which defines that it doesn't explicitly take energy to calculate data, however instead it takes energy to remove any data, as erasure is a vital step in computation.
Coulomb: C (after C. de Coulomb, 1736-1806): The derived SI unit of an electric charge, stated as the quantity of charge shifted by a current of 1 A in a period of 1 s; it therefore has units of A s.
Zeeman Effect: Zeeman line splitting (P. Zeeman; 1896): Zeeman Effect is the splitting of lines in a spectrum whenever the source is exposed to the magnetic field.
