ALGORITHM 2 - ABSTRACTION REDRAW:
SET UP: NUMBER THE LINES FROM THE ABSTRACTION
HERE DONE WAISTBAND THE LEFT TO RIGHT (FRONT THEN
BACK)
DECIDE THE BASE MEASURMENTS TO BE USED WITH THE SCALE
RATIO LATER
HERE AS 90CM HEIGHT FOR LEG PIECES AND 36CM WIDTH FOR
WAISTBAND
INTERPRETING THE DATA:
THE ALGORITHM - X = RELEVANT NUMBER FOR THIS STEP
1. SCLAE - X / 2 WHEN X < 5
THE SCALE (AT THIS POINT, LENGTH) OF THIS LINE SHOULD
BE X DIVIDED BY 2, IF X IS GREATER THAN 5 THEN THIS
SHAPE SHOULD BE DELETED AS THE SCALE IS TOO LARGE
(THIS CAN BE AN OPTIONAL PARAMETER)
2. ROTATE - BY X TIMES 60O CLOCKWISE
ROTATE THE LINE THROUGH 60O CLOCKWISE X TIMES,
KEEP ROTATING EVEN IF X IS GREATER THAN 6
3. MULTIPLY - BY X
MULTIPLY THE SHAPE BY X SO THAT THERE WILL BE X
IDENTICAL LINES NEXT TO EACH OTHER, DRAW EQUALLY
SPACED TO THE RIGHT OF THE FIRST LINE SO THAT THE
EDGES LINE UP HORIZONTALLY, IF THE FIRST LINE IS
HORIZONTAL, LINE UP VERTICALLY AND DRAW DOWN
4. PERPENDICULAR - + X / 2 FROM CENTRE WHEN X IS EVEN
ADD X/2 LINES THAT ARE PERPENDICULAR TO THE
EXISTING LINES, THEY SHOULD BE THE SAME SCALE AND
PLACED SO THAT THE CENTRE OF THE TWO GROUPS OF
LINES IS THE SAME, IF PERPENDICULAR LINES ARE ADDED
THE INDIVIDUAL LINES ARE NO LONGER SEPARATE
REPEATED SHAPES, THEY ARE ONE WHOLE GRID SHAPE
5. ALIGNMENT - ROTATE 90O CLOCKWISE WHEN X IS ODD
IF X IS ODD, THE ALIGNMENT OF THE WHOLE SHAPE SHOULD
BE CHANGED BY ROTATING IT 90O CLOCKWISE, IF X IS EVEN
THIS STEP SHOULD BE SKIPPED
6. HEIGHT:WIDTH - STEP 1 : 1 / X
GENERATE A RATION FOR THE SIZE OF THE SHAPE USING
THE SCALE FROM STEP 1 AS THE HEIGHT AND 1/X AS THE
WIDTH, TO GET THE EXACT MEASUREMENTS, INPUT A VALUE
FOR THE HEIGHT OF THE PART OF THE GARMENT THAT THIS
PIECE IS PART OF ( E.G. 86 CM FOR ALL PIECES THAT ARE
TROUSER LEGS IN RATIO 1:1/4 WOULD BE 86CM BY 21.5CM)
7. COMBINE - YES WHEN X < 2
WHEN X IS LESS THAN 2, COMBINE THE MEASUREMENTS OF
ALL SHAPES IN THE PATTERN PIECE TO EQUAL THAT
DECIDED BY THE RATIO, WHEN X IS GREATER THAN 2, APPLY
THE RATIO MEASUREMENTS TO EACH SHAPE INDIVIDUALLY
(E.G. 5 SHAPES WITH MEASUREMENTS 86CM:21.5CM IF X > 2
WOULD BE 5 SHAPES 86CM:4.3CM - LINED UP HORIZONTAL -
OR 17.2CM:21.5CM - LINED UP VERTICAL - IF X<2)
