Sciography : Point light source

In this IDEAAMOOC we will see how the sciography of 2D shapes and 3D objects is cast when the source of light is near the object.

Introduction
Sciography of a Square
Sciography of a Pentagon
Sciography of an Octagon
Sciography of an odd or complex shape
Sciography of a cube
Sciography with different light position
Sciography with single light source and objects around it

“Greek architecture taught me that the column is where the light is not, and the space between is where the light is. It is a matter of no-light, light, no-light, light. A column and a column, bring light between them. To make a column which grows out of the wall and which makes its own rhythm of no-light, light, no-light, light: that is the marvel of the artist.”

-Louis Kahn

Objects are defined by the light which falls on them and the shadow that they cast. Sciography is the study about the shade and shadow of an object or element in architecture. In architecture, we use this drawing technique of showing shade and shadows to understand the drawings more easily. Shade and shadows are also used to show the depth of an object. Light plays an important role in this being the source of these shade and shadows.

Point (Omni, Omni-directional) light simulates rays shining out from a single infinitely small point in space in all directions. A point light can mimic the effect given an Omni-directional local light source such as a light bulb and candle

In this chapter, we are going to learn about how a show is cast by an object when the light source is near the object. Previously, we have seen how the shadow is cast by an object when the light source is at infinity. When the light source is at infinity all the light rays that come are parallel to each other. Whereas, when the light source is somewhere near the object, for example, a study lamp, or a bulb in the room, or a street light etc. in such case the rays of light are not parallel to each other, they are radiating in radial format from the source. Because of this, the shadow that is cast appears to be tapering or vanishing towards the source of the light. We are also going to study how the shadow changes when the position of the light source changes.

In this IDEAAMOOC we will see how the sciography of 2D shapes and 3D objects is cast when the source of light is near the object.
