Diagrams of the Visual Field

I was going again throguh the preface to 'Brunellesch, Lacan and Le Corbusier' by Lorens Holm when I encountered a following thought: 'The image by which Narcissus is made known to himself, dissolves as soon as he tries to kiss it. He loves the object but all he gets is a lovely image; when he tries to attain the object, his world goes pear-shaped'.

My Illustration for a Quote

I think it is a very simple yet clever way of describing the metaphyscal process behind the physical process of seeing. This is not about actually seeing an image on a plane surface, but it is about imagining what is being that image: a real object or existing space. At the same time this drawn scheme introduces a possibility of seeing a space as an image. It suggests that there could be an invisible 'screen', which beholds the the whole area of space seen within our visual field.

My sketches of the 'Projection Simlified' and 'Projection Proper'
from 'Brunelleschi, Lacan and Le Corbusier' by Lorens Holm

These perspective triangles explains the relation between the viewer and the world. The lines in the 'Projection Simplified' explain the direction of the view, while the dashed lines in the 'Projection Proper' indicate that there is a difference between view and image and shows what is looked through the screen or image. 


Viewing Diagram Progression


I started with a very simple scheme, partially based on the projections from Holm's book. On the first one I indicated the position of the eye of the viewer towards the image and imaginary. Then, I overlapped it with a similar scheme, on which the eye of the viewer is positioned towards space and imaginary and in this scheme the image could be thought of as a virtual 'screen'. I placed blue lines on the third scheme indicating the 'image'. Image and the 'image' appear on the same line and again could be read as 'screen' and the 'image', while the other 'image' is fused with space. While I do call it space, it is a mere space representative, so it is a 'screen' itself. The sketch on the left below indicates that.

Sketches for Diagrams


The sketch on the right above is an idea for development of the scheme, in which I relocated the position of space and kept the 'image' in its place by putting a mirror instead of an image. The scheme below shows a step-by step development of this proposal.

Progression of the Diagram within the Device


My second step was to relocate the space in such a way, so the 'image' is formed by reflection. The first scheme presents a change made in the position of the space 'screen' and 'image'. Blue lines and arrows indicate the 'image' transfer. The second scheme contains information on position of the actual space in relation to the 'image' and 'sceen' as well as information on arrangement of these spatial elements in case of the 'image' relocation. The last scheme suggests possible solutions for updating the eventual scheme as by adding space outlines the the viewer's eye got trapped inside the space itself, while it is to be positioned outside the space. Options one and two are marked in orange on a scheme number three.
