Solid angle orientation formula_9, and distance from the viewer as: where the surface area of a sphere is . The solid angle of a cone with its apex at the apex of the solid angle, and with apex angle 2, is the area of a spherical cap on a unit sphere For small such that , this reduces to the area of a circle . The above is found by computing the following double integral using the unit surface element in spherical coordinates: This formula can also be derived without the use of calculus. Over 2200 years ago Archimedes proved that the
Volume (video game) over the country of England and runs the nation as a corporatocracy. It is hinted in-game that "Volume" is set in the same timeline as that of "Thomas Was Alone", also developed by Mike Bithell, but set after the events of that game. "Volume"s gameplay has been designed by Bithell similar to the stealth elements of the "Metal Gear Solid" series. The game is presented in a top-down third-person view of the Volume simulation, showing a floor layout, Robert's avatar, and several guards and other antagonists that patrol the area. Several different variety of guards exist, each which have different
