Abstract

At least two perforated materials called screens (4) are used. These screens are juxtaposed at a distance from each other, at least one of said screens being shaped.

Description

Ce procédé a pour but de représenter par un effet d'optique une sculpture ou un dessin en volume dans l'espace. The aim of this process is to represent a sculpture or a volume drawing in space using an optical effect.

Ce procédé permet d'obtenir un rendu visuel voisin de l'hologramme à partir d'une technique totalement différente. This process makes it possible to obtain a visual rendering close to the hologram using a completely different technique.

L'effet visuel est obtenu à partir de matériaux plans ajourés ou perforés (1), formant une trame qui peut être réalisée par des matériaux métalliques, plastiques ou toute matière opaque ou transparente. La trame peut être formée, découpée ou emboutie (2). Plusieurs trames peuvent être soudées entre elles, ou unies par tout autre procédé existant. The visual effect is obtained from perforated or perforated planar materials (1), forming a frame which can be produced by metallic, plastic or any opaque or transparent material. The frame can be formed, cut or stamped (2). Several frames can be welded together, or united by any other existing process.

L'effet d'optique de base est obtenu par la disposition de ces trames les unes par rapport aux autres. Elles sont juxtaposées, à une distance modulable entre elles, de face et alignées sur un même axe. The basic optical effect is obtained by the arrangement of these frames in relation to each other. They are juxtaposed, at a modular distance between them, from the front and aligned on the same axis.

Le nombre de ces trames est de deux au minimum, seul le passage de la lumière au travers de celles-ci déterminera la quantité maximum de trames à utiliser. The number of these frames is at least two, only the passage of light through them will determine the maximum amount of frames to use.

Elles seront peintes avec une peinture fluorescente qui va donner une luminosité accrue et renforcer l'effet de volume. I1 n'est pas obligatoire de peindre la première trame. They will be painted with a fluorescent paint which will give an increased luminosity and reinforce the effect of volume. It is not compulsory to paint the first frame.

Les trames peintes avec la peinture fluorescente seront éclairées pour obtenir les effets d'optique, avec des projecteurs à lumière noire ou lumière de E d(3) qui accentueront l'effet de volume et rehausseront les couleurs créant un effet de moirage et de luminescence. Cet effet visuel a pour conséquence de donner un volume et un relief nouveaux aux dessins (4) ou emboutissements qui figurent sur certaines de ces trames. The screens painted with fluorescent paint will be lit to obtain the optical effects, with black light or E d (3) light projectors which will accentuate the volume effect and enhance the colors creating a moiré and luminescence effect. . The effect of this visual effect is to give new volume and relief to the drawings (4) or stampings which appear on some of these frames.

On peut également utiliser une peinture non fluorescente et éclairer les trames en lumière blanche ou lumière naturelle, l'effet obtenu sera sensiblement différent, mais les effets de volume et de moirage restent les mêmes. One can also use a non-fluorescent paint and illuminate the frames in white light or natural light, the effect obtained will be significantly different, but the effects of volume and moiré remain the same.

On peut projeter à l'aide de projecteur de diapositives (5) ou tout autre projecteur, une image sur l'une des trames selon qu'on veut accentuer un effet, animer ou transformer l'effet initial. You can project using a slide projector (5) or any other projector, an image on one of the frames depending on whether you want to accentuate an effect, animate or transform the initial effect.

L'effet de mouvement produit naturellement par ces trames disposées à une distance modulable , peut être accentué par la mise en mouvement de l'une d'elles par tout moyen approprié ( ex. : la dernière trame peut tourner à l'aide d'un moteur à rotation lente). The movement effect produced naturally by these wefts arranged at a modular distance, can be accentuated by setting one of them in motion by any appropriate means (e.g. the last weft can rotate using a slow rotating motor).
