Not graphics related, but I think this is also why solar eclipses happen, in the sense that the projected area of the sun is completely obscured by the moon.

Is there any easy way to compute steradians? Like, for a circle, an equilateral triangle with a vertex at the center subtends pi/3 radians. Is there an equivalent easy calculation to compute how many steradians is, say above 45 degrees N on the Earth?
