Bioptical sculpture – dioptical perceptions

Extract from my publications as a result of my research.


Fig 2.19

Fig 2.20

Figure 2.19 shows a bioptical composition in space (bioptical sculpture). The forms in bioptical correspondence are placed in two tiered spaces. When viewing through the bioptical device, there occur bioptical and steroscopic images. Stereoscopic effects create a superspace. The composition elements placed in space seem to move in another space, with depths up to several scores of metres, penetrating other objects from the space. Figure 2.19 shows the photo of a model of a bioptical sculpture. It was used to prove the effects of binocular rivalry and colour fusion, combined with stereoscopic effects (transposition into hyperspace of a sculpture already made up of forms in space). In that photo some colours were retouched, which points to the possibility of introducing stimuli of binocular rivalry. In the case of a bioptical sculpture, the forms are set in two superposed areas Vd and Vs. In one of the areas the theme is developed with some restrictions for the component forms, while in the other area, other restrictions are added, namely those resulting from the stimulation of some bioptical effects.


Fig 2.21

In figure 2.21, the sculpture, viewed from a distance Do, may develop up to a certain depth limit Ps, to which there corresponds a limit observation area So. Viewed from outside the observation area, some forms are not bioptically correlated any longer (there occur image divisions for certain components, which are disturbing).
The photo in figure 2.19 was taken from outside area So. When the extracts of figure 2.19 (figure 2.20) are viewed with crossed eyes, spatial effects may be noticed only for the left forms.
The bioptical sculpture may be achieved only by accepting the tolerances for deviations from eye convergence, prescribed for binocular optical devices. By taking into account those tolerances, one may scale the limits of characteristics in figure 2.21. It is possible to diversify the forms of the sculpture not correlated bioptically, forms free of restrictions,

viewed from outside area So.

Figure 4.7 shows a sketch for a bioptical sculpture

Fig. 4.7

A tiered ensemble with paired off signs in bioptical correspondence, such as cuttings-out, outlines, prominences, as well as variously coloured surfaces. In addition to their tiered arrangement, forms also have a radial coordination, so that some inner surfaces provide coloured backgrounds for the cuttings-out of the other structures. The effects of standing out and floating are also obtained by breaking outlines with the help of prominences.
Sight A - main sight; Sight B - sight from above of the limits which circumscribe the forms in space.
D1, D2, D3 - observation directions to be preferred.
F1, F2, F3, F4 - support forms in space, including bioptical correspondents
a, a` - outlines in bioptical correspondence.
b, b` - succession of (cut out) triangles, correlated so as to obtain the reversal of the naturalistic perspective.
c, c` - coloured surfaces or cuttings out which induce retinal rivalry.
d, d` - correlated prominences, to be detached from the ensemble.
f, f` - elements which break the outlines.
n - noncorrelated outline.

Fig. 4.8

Figure 4.8 shows a montage meant to obtain a tactile-visual space (where one can see both surface rugosities and forms in space at different distances).
1 - bioptical sculpture (as in figure 2.19); 2 - Frame placed on the wall to limit painted forms in bioptical correspondence; 3 - Bioptical device on a stand.
The observer sees how the forms that make up the sculpture start to float in a dilated space; some come towards the observer, others penetrate the wall and seem to pass through the frame beyond it; the forms painted on the wall are spatially inserted with the forms carved in space in front of the wall and beyond it. The psychic influence in this case is much more powerful than that of the cinematic mixing.The presence of objects which seem to change induce much more powerful experiences than filmed scenes. The experience of viewing Jupiter's satellites through a telescope differs from that of seeing them on the TV screen. People would buy special glasses to view an eclipse of the sun, though it may be better seen on the TV screen.
