Projections

  • Georg Glaeser

Abstract

From the physical point of view, one-eyed seeing is nothing but projecting three-dimensional objects onto a projection surface (projection plane) by means of a lens (the camera lens or the lens of the eyeball). The brain is then more or less capable of “reconstructing” the objects in space, i.e., of estimating the distance of the objects with the help of size comparisons or shadows. Misinterpretations are reduced by two-eyed seeing, because it enables the brain to intersect corresponding projection rays in space.

    No parametrization by three numbers, however, can continuously parametrize the space of rotations. In the (C, T, τ)-parametrization, for example, the angle γ is ambiguous when the projection center is moved about during an animation and when CT̄ points to the z-direction.Google Scholar
