THEORY OF ARCHITECTURE 101 Ar. Juno Verlyn R. Magadia, UAP MODULE 2: FORM FORM FORM Architectural form is the point of contact between mass and space. FORM FORM Is the manner of arranging and coordinating the elements and parts of a composition so as to produce a coherent image.  FORM SHAPE The characteristic outline or surface configuration of a particular form. Shape is the principal aspect by which we identify and categorize forms.  FORM FORM: FORM: PYRAMID FORM: CUBE SPHERE SHAPE: CIRCLE SHAPE: SHAPE: TRIANGLE SQUARE  FORM Forms have visual properties of: SIZE The physical dimensions of length, width, and depth of a form. These dimensions determine the proportions of a form Its scale is determined by its size relative to other forms in its context.  FORM Forms have visual properties of: COLOR A phenomenon of light and visual perception that may be described in terms of an individual’s perception of hue, saturation, and tonal value.  FORM Forms have visual properties of: COLOR Color is the attribute that most clearly distinguishes a form from its environment. It also affects the visual weight of a form. FORM Forms have visual properties of: TEXTURE The visual and especially tactile quality given to a surface by the size, shape, arrangement, and proportions of the parts. Texture also determines the degree to which the surfaces of a form reflect or absorb incident light. PROPERTIES OF FORM PROPERTIES OF FORM Forms also have relational properties that govern the pattern and composition of elements: POSITION The location of a form relative to its environment or the visual field within which it is seen. PROPERTIES OF FORM Forms also have relational properties that govern the pattern and composition of elements: ORIENTATION The direction of a form relative to the ground plane, the compass points, other forms, or to the person viewing the form.  PROPERTIES OF FORM Forms also have relational properties that govern the pattern and composition of elements: VISUAL INERTIA The degree of concentration and stability of a form. The visual inertia of a form depends on its geometry as well as its orientation relative to the ground plane, the pull of gravity, and our line of sight.  SHAPE Refers to the characteristic outline of a plane figure or the surface configuration of a volumetric form. It is the primary means by which we recognize, identify, and categorize particular figures and forms.  SHAP E In architecture, we are concerned with the shapes of: Floor, wall, and ceiling planes that enclose space Door and window openings within a spatial enclosure Silhouettes and contours of building forms PRIMARY SHAPES SHAP E CIRCLE A plane curve every point of which is equidistant from a fixed point within the curve. SHAP E TRIANGLE A plane figure bounded by three sides and having three angles.  SHAP E SQUARE A plane figure having four equal sides and four right angles. SURFACES Refers to any figure having only two dimensions, such as a flat plane. The term, however, can also allude to a curved two-dimensional locus of points defining the boundary of a three- dimensional solid  SURFACE S CYLINDRICAL SURFACES Are generated by sliding a straight line along a plane curve, or vice versa. Depending on the curve, a cylindrical surface may be circular, elliptic, or parabolic. Because of its straight line geometry, a cylindrical surface can be regarded as being either a translational or a ruled surface.  SURFACE S TRANSLATIONAL SURFACES Are generated by sliding a plane curve along a straight line or over another plane curve. SURFACE S RULED SURFACES Are generated by the motion of a straight line. Because of its straight line geometry, a ruled surface is generally easier to form and construct than a rotational or translational surface.  SURFACE S ROTATIONAL SURFACES Are generated by rotating a plane curve about an axis. SURFACE S PARABOLOIDS Are surfaces all of whose intersections by planes are either parabolas and ellipses or parabolas and hyperbolas. SURFACE S PARABOLAS Are plane curves generated by a moving point that remains equidistant from a fixed line and a fixed point not on the line. SURFACE S HYPERBOLIC PARABOLOIDS Are surfaces generated by sliding a parabola with downward curvature along a parabola with upward curvature, or by sliding a straight line segment with its ends on two skew lines.  CURVED SURFACES SADDLE SURFACES Have an upward curvature in one direction and a downward curvature in the perpendicular direction. Regions of downward curvature exhibit archlike action while regions of upward curvature behave as a cable structure. If the edges of a saddle surface are not supported, beam behavior may also be present. WALT DISNEY CONCERT HALL 111 S GRAND AVE, LOS ANGELES, CA 90012, UNITED STATES FRANK GEHRY
