PSYB51H3 Chapter Notes - Chapter 6: Aerial Perspective, Vanishing Point, Horopter
Document Summary
The ability to perceive and interact with the structure of space is one of the fundamental goals of the visual system. Realism: a philosophical position that there is a real world to sense. Positivism : a philosophical position that all we have to go on is the evidence of our senses, so the world might be nothing more than an elaborate hallucination . Parallel lines remain parallel as they are extended in space, objects maintain their size and shape in the real world. But, euclidean geometry is not the only geometry, the geometry of retinal images of that world is non-euclidean. The geometry becomes non-euclidean when the d world is projected onto the curved 2d surface fo teh retina. We reconstruct teh world from 2 non-euc inputs: teh two distinct retinal images. They differ because the retinas are in different places. i. e just as u and the person next to u sees different views of the world.
