REPRESENTING DAYLIGHT INCIDENT ANGLES
When graphically analyzing incident angles of daylight, the sun may be
treated as infinitely distant, i. e., it can be assumed to cast parallel rays.
A common diagraming error made by beginning students is to treat the
sun as if it were a local point source.
For a more detailed discussion of solar-angle geometry, refer to p. 144 in
The Architect’s Studio Companion.
