| CAST SHADOWS FROM A SINGLE POINT LIGHT SOURCE.
HOPEFULLY THIS DIAGRAM IS SELF-EXPLANATORY, BUT BASICALLY SHADOWS HAVE THEIR OWN VANISHING POINTS WHICH CAN BE ARBITRARILY PLACED AS SHOWN. THE LIGHT VANISHING POINT IS PLACED SOMEWHERE IN THE SKY AS SHOWN. IN THIS EXAMPLE, THE SHADOW VANISHING POINT IS PLACED ON THE HORIZON LINE, WHICH INDICATES THAT THE LIGHT SOURCE IS VERY FAR AWAY, BASICALLY ON THE HORIZON. I COULD HAVE LOWERED THE VANISHING POINT (BUT KEEPING ITLINED UP BELOW THE VANISHING POINT OF THE LIGHT), WHICH WOULD GIVE THE EFFECT OF THE LIGHT SOURCE MOVING CLOSER TO US. IF I LOWERED THE SHADOW V.P. UNTIL IT WAS BELOW THE CUBE IN THE DRAWING, THE SHADOWS WOULD START TO POINT AWAY FROM US, TOWARD THE TOP OF THE PAGE, AND THIS WOULD INDICATE THAT THE LIGHT SOURCE IS BEHIND THE CUBE. OBVIOUSLY THERE IS A LOT MORE TO THIS, BUT IT'S ONE SIMPLE WAY OF CONSTRUCTING A CONVINCING LOOKING SHADOW FOR THIS EXERCISE. |
