Solid angle to the unit sphere with center P, which can be calculated as the surface integral: where formula_5 is the unit vector corresponding to formula_6, the position vector of an infinitesimal area of surface with respect to point P, and where formula_7 represents the unit normal vector to . Even if the projection on the unit sphere to the surface S is not isomorphic, the multiple folds are correctly considered according to the surface orientation described by the sign of the scalar product formula_8. Thus one can approximate the solid angle subtended by a small facet having flat surface area ,
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
