Abstract

The invention relates to a binocular method for drawing and observing. This method consists of two separate but mutually dependent techniques: a. Drawing two drawings of the same object or from two different angles, on the same board; b. Observing an imaginary point located at a defined distance between the observer and the drawing. This method is intended for the wallpaper industry, the tiling industry, the stained-glass-window industry, the fencing-netting industry, the monumental art industry, and the optical industry in general: for the synthetic image of television, photography and cinema. The essential purpose of this invention is to dispense with optical equipment such as: two-colour spectacles, stereoscope, hologram laser or the rippling (corrugating) of the support media. In order to see the drawings or synthetic images in 3-D.

DESCRIPTION PROCEDURE FOR DRAWING AND UDIR IN RELIEF
The present invention relates to a method for drawing and seeing in relief.

Les images dessinées traditionnellement représentent une vision monoculaire en perspective cavalière ne donnant qu'une idée imparfaite de l'effet de profondeur. The images traditionally drawn represent a monocular vision in perspective, giving only an imperfect idea of the effect of depth.

Les images du type hologramme nécessitent le recours de techniques et matériels extérieurs au dessin (Stéréoscope, Lasers, Lunettes bicolores,
Striage, etc...).Hologram type images require the use of techniques and materials external to the drawing (Stereoscope, Lasers, Two-color glasses,
Streaking, etc ...).

Le procédé pour créer et voir des objets dessinés en relief est caractérisé en ce qu'il consiste à dessiner l'image vue par l'oeil gauche d'un observateur en perspective cavalière décalée sur la droite d'un axe de symé- trie et l'image vue par l'oeil droit en perspective cavalière décalée sur la gauche du même axe et en ce qu'il consiste à observer un point ou un espace imaginaire situé entre l'observateur et le dessin permettant d'obtenir la coincidence des deux dessins vus par l'oeil gauche et par l'oeil droit ce cui donne une troisieme image en relief. The process for creating and seeing objects drawn in relief is characterized in that it consists in drawing the image seen by the left eye of an observer in cavalier perspective shifted to the right of an axis of symmetry and the image seen by the right eye in cavalier perspective shifted to the left of the same axis and in that it consists in observing an imaginary point or space located between the observer and the drawing making it possible to obtain the coincidence of the two drawings seen by the left eye and by the right eye this one gives a third image in relief.

Selon une première variante à la description du procédé ci-dessus, le dessin en relief peut être observé d'une manière concave s'il était convexe, et vice versa. L'inversion du sens de la vision en relief est caractérisée par le fait de dessiner à gauche de l'axe de symétrie (et non à droite) la vue observée par l'oeil gauche (1) et à droite la vue observée par l'oeil droit (2). According to a first variant to the description of the above process, the relief drawing can be observed in a concave manner if it was convex, and vice versa. The reversal of the direction of the relief vision is characterized by the fact of drawing on the left of the axis of symmetry (and not on the right) the view observed by the left eye (1) and on the right the view observed by l 'right eye (2).

Selon une deuxième variante à la description du procédé ci-dessus, 1 in~ ~ version du sens de la vision en relief sans modifier le dessin, est caractérisée en ce qu'elle consiste à porter un regard divergent de l'oeil gauche (1) sur A et l'oeil droit (2) sur Selon la figure 9 (et non plus un regard convergent en P). According to a second variant to the description of the above process, 1 in ~ ~ version of the sense of vision in relief without modifying the drawing, is characterized in that it consists in wearing a divergent look from the left eye (1 ) on A and the right eye (2) on According to Figure 9 (and no longer a convergent look at P).

Selon un mode de réalisation-preférentiel en observant l'espace découpé dans le cache occulteur selon ma figure 10, l'observateur voit un paralléléni- pède cubique constitué par l'osmose des deux dessins de la figure 7. According to a preferred embodiment, by observing the space cut out in the blackout cover according to my FIG. 10, the observer sees a cubic parallelepede constituted by the osmosis of the two drawings of FIG. 7.

Selon une variante du procédé ci-dessus, les dessins de la figure 7 peuvent être remplacés par des projections filmées, statiques ou en mouvement, observées sur l'écran formé par l'ouverture du cache occulteur selon la figure 10. According to a variant of the above method, the drawings in FIG. 7 can be replaced by filmed projections, static or in motion, observed on the screen formed by the opening of the blackout cover according to FIG. 10.

j) Présentation des dessins
La figure 1 : représente un parallélépipède A.B.C.D.E.F.G. avec des
diagonales aux sommets se croisant en un point 0, observé par l'oeil gauche 1 La figure 2 : : représente l'objet vu de gauche, la lettre N étant le nivea des yeux de l'observateur.j) Presentation of the drawings
Figure 1: represents a parallelepiped ABCDEFG with
diagonals with vertices crossing at a point 0, observed by the left eye 1 Figure 2:: represents the object seen from the left, the letter N being the level of the eyes of the observer.

La figure 3 : représente le parallélépipède en élévation vu par 1. Figure 3: shows the parallelepiped in elevation seen by 1.

La figure 4 : représente la parallélépipède observé par l'oeil droit 2. FIG. 4: represents the parallelepiped observed by the right eye 2.

La figure S : représente le parallélépipède vu de gauche. Figure S: represents the parallelepiped seen from the left.

La figure 6 : représente le parallélépipède en élévation observé par 2. Figure 6: shows the parallelepiped in elevation observed by 2.

La figure 7 : représente les deux dessins sur un meme fond cadrillé. Figure 7: shows the two drawings on the same framed background.

ia~flqufe~e : montre la technique et le geste éventuel à accompli plir pour observer le point imaginaire P. ia ~ flqufe ~ e: shows the technique and the possible gesture to be performed to fold to observe the imaginary point P.

La figure 9 : : permet d'expérimenter la technique en se situant environ à 80 cm et en faisant le geste éventuel de la figure B par rapport aux points
A et B en gras. Les points A et B sont aléatoires, le procédé s'adapte sur tous les supports opaques ou transparents.Figure 9:: allows you to experiment the technique by being approximately 80 cm away and making the possible gesture of Figure B in relation to the points
A and B in bold. Points A and B are random, the process adapts to all opaque or transparent supports.

La figure 10 : représente deux dessins selon la figure 7 que l'on visualisent en relief à travers un cache occulteur constitué d'une feuille de papier percée en son centre d'une ouverture carrée et située sur un plan entre le dessin et l'observateur de telle manière que la vision de l'oeil gauche corresponde au dessin de droite et que la vision de l'oeil droit corresponde au dessin de gauche. FIG. 10: represents two drawings according to FIG. 7 which are visualized in relief through a blackout cover made up of a sheet of paper pierced in its center with a square opening and situated on a plane between the drawing and the observer in such a way that the vision of the left eye corresponds to the drawing on the right and that the vision of the right eye corresponds to the drawing on the left.

k) L'originalité du procédé est multiple, a) l'osmose de deux techniques
d'une part la technique du dessin proprement dit selon la figure 7, d'autre 1) m) part la technique d'observation selon les figures 8 et 10.k) The originality of the process is multiple, a) the osmosis of two techniques
on the one hand the actual drawing technique according to FIG. 7, on the other hand 1) m) on the other hand the observation technique according to FIGS. 8 and 10.

b) la vision en relief obtenue en regardant un point imaginaire P (regarder RIEN).b) the relief vision obtained by looking at an imaginary point P (looking at NOTHING).

c) possibilité d'inversion de la vision en relief (convexe à concave ou vice versa).c) possibility of reversing the relief vision (convex to concave or vice versa).

Le procédé caractérisé par le fait que la rigidification du dessin permet la création de la sculpture sans support. The process characterized by the fact that the stiffening of the design allows the creation of the sculpture without support.
