In geometry, a solid angle (symbol: Ω) is a measure of the amount of the field of view from some particular point that a given object covers. That is, it is a measure of how large the object appears to an observer looking from that point. The point from which the object is viewed is called the apex of the solid angle, and the … See more An object's solid angle in steradians is equal to the area of the segment of a unit sphere, centered at the apex, that the object covers.
