SIGHT LINEA SIGHTLINE OR VISUAL AXIS IS A NORMALLY OBSTRUCTEDLONE OF SIGHT BETWEEN AN INTENDED OBSERVER OR SPECTATOR AND A STAGE ARENA OR MONUMENT.

FOR EXAMPLE, SIGHTLINES ARE PARTICULARLY IMPORTANTCONCIDERATION IN THEATER AND STADIUM DESIGN, ROADJUNCTION LAYOUT AND URBAN PLANNING.

IN CITIES SUCH AS LONDON, CONSTRUCTION WITNIN SIGHTLINEIS RESTRICTED TO PROTECT THE KEY VIEWS OF FAMOUS LANDMARKS.

EMERY THEATRE IN CINCINNATI,OHIO.DESIGN IS BASED ON ‘ISACOUSTIC CURVE’.[FIRST CONCERT HALL IN U.S TO HAVENO OBSTRUCTED SEATS]

ROLE OF SIGHT LINE IN SITTING ARRANGEMENTS OF AUDITORIUMSTAGGERED SITTING

1:To provide best visibility from any seat, no patron should sit exactly in front of any other patron unless more than one row distant . This requirement makes it necessary to stagger seats .

2:Staggering is accomplished by the non uniform placement of seats of varying widths in succeeding rows .

3: Unless the walls of the theatre are parallel (which is acoustically hazardous), it is extremely unlikely that more than a very few rows can be made up of seats of uniform width.

4:Seats are made with uniform standards and interchangeable backs and seats so that a wide variation of seat width is possible ; a variation from seat to seat of an inch or two, cumulative enough to accomplish satisfactory stagger

Important factors in theater design are clear and unobstructed sight lines to the screen, the vertical position of the screen being oneof the controlling factors. In the past, the screen position was influenced by the stage level, and the physical conditions of the theater,such as the projection of the balcony over the orchestra floor, theheight of the proscenium, and the projection angles.

screen location on the stage somehow became a b e drule and notwithstanding the fact that the function was differentmany motion picture theater? came to be built still holding on to thetraditional stage of the “legitimate” along with the rule of thumb thatthe screen should be located 12‘to 24 inches above the stage.

The following methods for staggering the chairs are

5:Varying chair widths €or all rows with a varying aisle indent and sometimes no indent at all. This method is more corrective but requires special chair widths.

6: By using three chair sizes in each row and alternating the orderof the chair sizes every other row, for example, five 19-inch, four 20-inch, five 21-inch in all even rows; with five 21-inch, four 20-inch,five 19-inch in all odd rows. There would be no aisle indent as allaisle standards would be in alignment, nor would there be any loss ofchairs

RELATIONSHIP BETWEEN SIGHTLINE , HEIGHT & DISTANCE OF STAGE AND VIEWER

*SIGHTLINE IS THE ONE OF THE IMPORTANT FACTOR CONSIDERED DURING DESIGNING AN AUDITORIUM HALL.

*GOOD SIGHTLINES ALLOW SPECTATORS TO SEE ALL AREAS OF A VENUE STAGE OR FIELD OF PLAY. TO ENSURE THIS DESIGNERS UTILIZE THE C-VALUE

*THE ARCHITECTS AND ENGINEERS WHO DESIGN STADIUMS =HAVE TO THINK VERY CAREFULLY ABOUT THE WAY THE SEATS ARE LAID OUT IN ORDER TO SQUEEZE IN AS MANY SEATS AS POSSIBLE WITHOUT COMPROMISING ON THE QUALITY OF THE VIEW. THEY USE AN ALGEBRAIC EQUATION TO DETERMINE THE QUALITY OF VIEW, KNOWN AS THE “C VALUE”, WHICH IS THE VERTICAL DISTANCE IN MM BETWEEN YOUR LINE OF SIGHT AND THE EYES OF THE PERSON IN FRONT.

AN ARCHITECT WOULD DECIDE ON THE C VALUE THEY WISH TO HAVE AND USE IT IN ANOTER EQUATION TO FIND OUT THE REQUIRED HEIGHT OF THE STEPS BETWEEN EACH ROW OF SEATS.

R= IS THE VERTICAL HEIGHT BETWEEN THE EYE AND THE POINT OF FOCUS

D= IS THE HORIZONTAL DISTANCE BETWEEN THE EYE AND THE POINT OF FOCUS

N= IS THE SEATING STEP HEIGHT T= IS SEATING STEP WIDTH

VIEWING ANGLES AND SLOPE

•IT IS THE MAXIMUM ANGLE AT WHICH A DISPLAY CAN BE VIEWED WITH ACCEPTABLE VISUAL PERPORMANCE

•ANGULAR RANGE IS CALLED THE VIEWING CONE DEFINED BY A MULTITUDE OF VIEWING DIRECTION.

•VIEWING ANGLE IS MEASURED FROM ONE DIRECTION TO THE OPPOSITE DIRECTION, GIVING A MAXIMUM OF 180 FOR A FLAT, ON SIDED SCREEN.

•A PROPER SLOPE MUST BE GIVEN TO THE FLOOR (IN THE SHAPE OF PARABOLIC CURVE) TO HAVE OBSTRUCTION FREE VIEW.

IMAGE SHOWING POSITION OF EYE ACCORDING TO DISTANCE

•VIEWING ANGLE DEPENDS UPON THE DISTANCE BETWEEN THE VIEWER AND THE PERFORMER.

•VERTICAL AND HORIZONTAL ANGLES DECREASES AS DISTANCE INCREASES

•IF IT IS A DOWNWARD SLOPE THEN THE NORMAL LINE OF SIGHT SHIFTS DOWNWARD.

•IF IT IS AN UPWARD SLOPE THEN IT SHIFTS UPWARD

IMPORTANCE OF SIGHTLINEA GOOD AUDITORIUM WILL HAVE GOOD SIGHT LINES ,BUT THE QUALITY OF SIGHTLINES DEPENDS TO A LARGE EXTENT ON THE NATURE OF THE PROGRAMMING. WHATEVER THE PERFORMANCE, IT IS IMPORTANT THAT THE AUDIENCE EXPERIENCE IT TOGETHER AND SEE EACH OTHER AS WELL AS THE STAGE. THE AUDIENCE’S SIGHTLINE IS AN

IMPORTANT ASPECT OF THE DESIGN OF VIEWING VENUES.

FOR AUDITORIUM AN ALGORITHM IS USED TO CHECK THE SIGHT LINE FROM A SEAT TO DETERMINE IF IT IS BLOCKED. DESIGN OF PROPER SIGHTLINES INCLUDES RESOLVING BOTH TECHNICAL AND AESTHETIC ISSUE.
