Perspective in the world

The Light Environment. We start with the light environment as a viewer would experience it naturally. The space around the viewer is filled with a dense, rich scattering of light, coming at him from all directions and distances, reflected from every surface and even scattered by the atmosphere. the light environment The viewer is also alive and continually moving — shifting his gaze, turning his head, leaning to one side or another, stepping forward or backward, walking or sitting or lying down. The Stationary Viewer. the stationary viewer Once we freeze the viewer's location, posture and gaze, we necessarily fix the viewer's visual cone (what we would call the visual field in other contexts). The fixed visual cone is defined by a fixed apex, the viewpoint, and a fixed direction of view (also called the central ray, axis of sight or principal visual ray), which represents foveal ("in focus") vision at the center of the visual field. The Ground Plane. the ground plane Distance Measurement.

Pics and It Didn’t Happen Image by Brad Feuerhelm The tension between experience for its own sake and experience we pursue just to put on Facebook is reaching its breaking point. That breaking point is called Snapchat. It is a nostalgic time right now, and photographs actively promote nostalgia. A photograph is made of time as much as it is of light — a frozen shutter-speed-size gap of the present captured within a photo border. On Snapchat, images have no such future. By refuting the assumption of the permanence of the image, Snapchat is a radical departure. The temporary photograph’s abbreviated lifespan changes how it is made and seen, and what it comes to mean.

PERSPECTIVE LINEAIRE - LES BASES DU DESSIN ... et de la PEINTURE 29 septembre 2007 6 29 /09 /septembre /2007 14:35 La perspective linéaire est certainement le moyen le plus facilement décrypté par le cerveau. Cette perspective permet de suggérer au mieux la profondeur. Avant d'expliquer les 2 principales perspectives linéaires, commençons ici par définir quelques termes employés. Plan du sol : plan sur lequel est positionné l’observateur Ligne du sol : prend naissance à l’intersection du plan du sol et du plan du tableau Plan du tableau : plan vertical du tableau PFf : prend naissance à la perpendiculaire de la vision de l’observateur et du plan du tableau. LH = ligne d'horizon (là où le ciel touche la mer) Correspond toujours au niveau horizontal des yeux. Les 4 exercices qui vont suivre représentent le même sujet vu par un observateur dans des positions et placement différents. - Le niveau des yeux NY est représenté par une ligne discontinue rouge. - La position de l'observateur est représentée par triangle rouge.
