PROGRAMME OBJECTIVES


Sawu

as a software
programme

was

designed

to

draw

2D and 3D
images

from

the

rectilinear

constructions

of
warp
-
faced

weaves
,
which

are
the

most

complex

and
interesting

in
the

Andean

region
.


In
terms

of
techniques
,
it

allows

users

to

draw

plainweave
,
balanced

weaves
,
ladder

techniques
, simple and
complex

selected

and
reselected

techniques

(
with

floating

and
supplementary

threads
), and doble
cloth
.


Sawu

cannot

draw

crossed

warps
,

transposed

warps

or

oblique

interlacing

techniques
, and
another

programme

InaSawu

was

designed

in
the

AHRC
project

with

this

in
mind
.


In
terms

of
structures
,
Sawu

draws

up
to

8
levels

of
warp
.


It

allows

users

to

appreciate

the

trimensionality

of
Andean

textiles.


It

allows

greater

analysis

and
documentation

of
Andean

textiles.

DEFINITION


As a software
programme
,
Sawu

was

designed

using

Visual Basic
version

6.0.


The

design

derives
from
:

o
Knowledge

about

technological

tools

that

form

part

of
language
.

o
Mathematical

knowledge

related

to

geometry
,
management

of matrices,
trignometric

functions

and
others
.

DEFINITION (Cont.)

o
The

design

of
Sawu

also

draws

on

knowledge

of
the

textile

domain
,
with

the

support

and
supervision

of
the

domain

experts

in
the

project
.

o
And
knowledge

of VRML (
Virtual
Reality

Modeling

Language
)
technology

for

the

construction

of 3D
images
.

FUNCTIONING


Sawu

facilitates

textile

designs

in 2D.


These

designs

can be
stored

in a data base
or

saved

in
an

external

file.


They

can
also

be
exported

as
an

image

file in “.
bmp
” (
bitmap
).

FUNCTIONING (Cont.)


It

is

then

possible

to

generate

a 3D
image

of
this

design
.


This

3 D
image

can be
saved

as a VRML file
with

the

extension

“.
wrl
”.

UTILITY


As a
result
,
the

Sawu

programme

allows

you

to

represent

an

image

or

textile

structure

in 2D
or

3D.

PROGRAMME FORMAT


The

programme

format

consists

basically

of a
grid

that

replicates

the

2D
design
,
based

on

the

upper

level

of
the

textile

layers
.


You

simply

make

a
click

on

a
cell
, and
colour

in,
or

draw

the

design
.

PROGRAMME
FORMAT (
Cont
.)


There

is

a
Menu

and
Toolbar
,
to

facilitate

work

with

the

Grid
.


There

is

also

information

about

the

number

of
warp

and
weft

threads

to

be
used
.

THE GRID


A
drawing

of a single
textile

face

is

done
with

this

Grid
, in
which

the

columns

represent

the

warp

threads
, and
the

rows

represent

the

weft

threads
.

THE GRID (Cont.)


Depending

on

the

number

of
textile

layers

you

are
working

with
,
each

column

of
the

Grid

can in
fact

represent

one

or

various

warp

threads
.


This

means

that

if

you

are
working

with

a
weaving

with

3
layers
,
then

a
column

represents

the

combination

of
these

3
warp

threads
.


In
this

way
,
Sawu

assimilates

the

phenomenon

of
compression

that

exists

between

the

warp

threads

in a
real
textile
.



THE GRID
(Cont.)

THE COLOUR GRID


Besides

the

Design

Grid
,
there

is

also

a
Colour

Grid
.


This

is

found

in
the

upper

part

of
the

Design

Grid
.

THE COLOUR GRID (Cont.)


The

Colour

Grid

contains

the

colours

of
the

warp

threads

making

up
the

textile
.


So
both

Grids

have

the

same

number

of
columns
.


You

can control
the

colour

of
each

warp

thread

from

this

Colour

Grid
,
by

making

a
double

click

on

the

corresponding

cell
.

OTHER APPLICATIONS


Sawu

can
also

be
used

for

drawing

reconstructed

textile

figures
that

have

been

damaged
,
by

applying

the

same

technique
:

SPA:
1356 (ILCA_SPA001)

OTHER APPLICATIONS (Cont.)


Simple
selected

technique

with

a
count

of
2|2,
applied

to

the

damaged

textile

to

permit

its

reconstruction
:

SPA:
1356 (ILCA_SPA001)

OTHER APPLICATIONS (
Contd
.)


Sawu

can be
used

to

identify

damaged

textile

motives,
again

by

drawing

the

same

technique
:

SPA:
1356 (ILCA_SPA001)

CONCLUSIONS


Sawu

permits

the

elaboration

of 2D
drawings

of
either

the

upper

face

of a
given

textile
,
or

else

of
an

invented

design
.


With

Sawu

it

is

possible

to

configure
the

colours

of
the

individual
warp

threads

and
weft

threads

that

make

up a
textile
.


Sawu

permits

working

with

textile

of
various

layers

(up
to

8).


Sawu

can
automatically

generate

the

inverse

of a
textile

design

with

more
than

2
layers
,
through

the

process

of
selecting

colours

by

the

User
.


The

design

achieved

can be
saved

or

exported

in a 2D
configuration
.


Sawu

also

allows

you

to

show a
profile

section

through

one

or

various

warp

threads
,
for

greater

textile

analysis
.

CONCLUSIONS (Cont.)


In
addition
,
Sawu

permits

the

3D
representation

of a
design

made

with

this

programme
.


The

3D
construction

can
include

a
whole

design

of
just

parts

of a
design
,
through

the

use of 3
independent

windows

.
This

helps

visualise

better

the

textile

structure
.


It

is

possible

to

save

the

3D
image

constructed

as a VRML
image
.



So
the

Sawu

programme

is

a
working

tool

that

permits

the

2D
and 3D
representation

of
textile

structures

and
techniques

in
warp
-
faced

weaves
,
for

later

analysis
.
