1. The document discusses different concepts related to shape including how it is defined by contour, interior contour/surface, and silhouette. 2. It describes different types of shapes such as closed/open, regular/irregular, and symmetrical/asymmetrical. 3. Relations between shapes are explored including resizing, contact, separation, transparency, overlap, and intersection which can provide cues about depth.

3. • Everything
around us is
shaped.
Matter can
not exist
without shape
or form. Sonia Delaunay

4. FORM AND SHAPE
A triangle, which is two
dimensional, is a shape, but
a pyramid, which is three-
dimensional, is a form.

5. •Definition:
An enclosed
area defined
and
determined by
other art
elements
(colour,
textures, etc.);
2-dimensional.

6. By its contour: By its interior
Lines that surround contour/surface: lines,
and define the edges of
a subject, giving it shape. colours and
textures
that
form the
surface
of a shape.
By its silhouette:
representation of the shapes
through a single colour or tone.

7. A) Closed
Shape:
Space that is
completely
enclosed by
a line, or
unbroken
contour.
Paul Klee

8. B) Open
Shape:
space that is
not
completely
enclosed by
a line.
Turner

9. •A) Regular:
both sides and
angles equal ;
also the
circumference.
•B) Irregular:
all others.

10. •A) Positive:
shape is
perceived as
part of a space.
•B) Negative:
shape is
perceived as a POSITIVE NEGATIVE
void.

11. •A) Symmetrical: a Symmetrical Asymmetrical
shape that has two
identical halves in
both shape and size
divided by one o
more axes.
•B) Asymmetrical:
the absence of
symmetry.

12. •1. Resizing: to create
the illusion of distance
and closeness we can
vary the size of the
shapes, placing the
largest on the bottom
and the smallest on
top.

13. •2. Contact: if we
place two objects in
contact we are
placing them at the
same distance from
the observer.

14. •3. Separation: the
shapes can be
separated
diagonally to
transmit a sense of
depth and more
space between
them.

15. •4. Transparency:
shapes that are
situated beneath a
transparent one,
give the sensation
of being behind it, a
little further.

16. •5. Overlap:
to obtain the
sensation that a
shape is behind
another, we will
hide a part of it.

17. •6. Intersection:
it occurs when two
shapes intersect
creating a new
one.

18. • The resources used to
suggest depth in an image are
based on our perception of
size:
• Two identical shapes
located in the same
horizontal line do not
produce any feeling of depth.

19. • LAYOUT
The sense of
distance is
accentuated when
the shapes are
located on different
horizontal lines
and the smaller one
above.

20. • RESIZING
Experience shows
that a distant object
it seems to be
smaller, so, between
two shapes, the
smaller will seem
the farthest.

21. • OVERLAP
Due to experience
we know that if
two objects are in
the same line of
sight, the closest
hide the other.

22. • CONTRAST
The use of different
colours and light
also gives us a sense
of space.

23. • SHARPNESS AND
TEXTURES
The sharpness and
detail of the textures
indicate that shapes are
on the foreground,
while the blurred
contours suggest that
they are on the
background.
