4 The Formative Grammar of Art - B
- Creation of Illusions -

Illusions and Impossible Diagrams

1 Illusion
1 Psychology of illusions
(1) Illusion on distortion of shapes / (2) Illusion on shifts in line positions and angles
(3) Distortions of sight on vertical direction / (4) Differences in views of the same size
(5) Illusion on brightness / (6) Visual angle designation

2 Double views
(1) Double images / (2) Coexistence of normal and inverse illustrations
(3) Reversal perspective illusions

2 Impossible diagrams
1 Various impossible diagrams
(1) The use of reversal perspective illusion
(2) Illusions by intersection of shapes
(3) Impossible diagrams using the Penrose Triangle
(4) Solids which transform into different shapes

Illusion of Three Dimensions

3 Expression with three-dimensional effect
1 Ideas to express a shape and its arrangement with three-dimensional effect
(1) Use of oblique lines and oblique projections
(2) Expression by density / (3) Shapes concentrating toward a point
(4) Radial lines / (5) Envelopes
(6) Expression of depth by shapes with different sizes / (7) Overlapping

2 Expression of three-dimensional effect using colors and textures
(1) Effect of gradation (shading) / (2) Three-dimensional effect by texture and gradual
change of brightness
(3) Three-dimensional effect using colored surfaces

3 Expression of three-dimensions using destruction of system
(1) Parallel lines changing in direction / (2) Deformed square lattices

4 Expression of transparency
1 Expression using points
2 Expression using lines
3 Expression using planes

Illusion of Four Dimensions

5 Movement
1 Studies on arrangements
(1) Movement of breaking out / (2) Movement with has the image of progressive destruction
(3) Effect of obliqueness / (4) Image of rotation
(5) Concentrated movements towards a fixed direction

2 Studies on shapes
(1) Wave forms / (2) Deviation, movement, and repetition of shapes
(3) Vibration, curves, and others

3 Studies on colors

6 Rhythm
1 Repetition
(1) Expression of rhythm using congruent shapes
(2) Expression of rhythm using similar shapes
(3) Expression of rhythm using resembling shapes
(4) Rhythm and arrangement

2 Complicated rhythm
(1) Assembly of gradually changing shapes / (2) Use of multiple structures

Deformation

7 Deformation and metamorphosis
1 Coordinate change
2 Anamorphosis - Deformation by mirrors -
3 Metamorphosis - Deformation by lenses -
