Ban Gleán: Here are my questions: The pictorial space is often described within a euclidean plane, or within a flat 2D "window". I was trying to think of examples where that is not the case, such as with a globe or other image painted on a sphere, or a column, or even on the inside of a dome. How would some of the concepts change with these new surface geometries? Thinking about how pictorial space offers the illusion of depth through the mind making use of context clues made me think of holograms, and how they work by also giving the eye the same sensory information as an actual 3D object. I don't quite understand how they work, but was wondering how one could use them to further investigate "seeing."
Uranus: Question: When viewing pictorial space, how is the observer impacted by the description of the work as a “drawing,” “painting,” “sculpture,” or “photograph,” etc.? What visual cues are imbued with this naming, medium-indicative language?
Earth: I wonder if the differences in vision between tigers and lambs (presented in Koenderink, Pictorial Space) have any effect on perception of stimuli. Does an increased binocular overlap, increased depth perception in a near field of view make objects in that field of view more likely to be viewed as prey? Does a reduction in binocular overlap and consequent flattening of the visual scene make objects appear more predatory? And does that affect how we perceive objects and scenes when seen through different lenses (surveillance cameras, drones, the internet)?
Asuras: Here are my questions, thank you! - “Visual artists are far ahead of the engineers, but their knowledge is partly implicit and certainly hard to mine.” (Koenderink et al., 2012) What are ways in which the knowledge that visual artists have can be used to further vision research? - In Koenderink et al (2012), why is the picture plane described in Cartesian coordinates (x,y)? Would this coordinate system be as relevant if the object being observed was not a flat picture (e.g. not a canvas painting) but a 3-D sculpture?​ - Suppose we consider a blind person who was recently operated on successfully to gain their vision. If "percepts correspond to ... the historical significance of proximal stimuli" (as stated in the conclusions of Purves et al, 2001), then what unique challenges would this person face in detecting accurate percepts initially?
Hoags Object: My question is: "What are the implications for the order of visual processing and possible hierarchy of cues that arise from rejecting the retinal ratio theory as in Gilchrist 1977?"
Celestis: My question is: I know we didn't talk a lot of neuroscience in this class, but I am wondering is there any differences in the brain activities when we see actual 3D scenes vs pictorial images? I assume that both of them on our retinas would all be 2D, but does the brain or any brain circuits distinguish these two stimuli differently?
OP: @ Celestis, this only begins to answer your question, but this Snow et al. (2011) paper asks the same of 3D vs 2D vision, with the finding that neural activity is quite different https://www.nature.com/articles/srep00130
Sateda: My question is this:From the article of Jan Koenderink he did work on an experimental psychology /Pictorial space and visual spaces.After all those experiments, did he ever get a result on brain waves alterations ? Pictorial space :which is not necessarily connected with Visual spaces,Could make a permanent shift with their brain and cognitive behavior (Viewers )? If yes ,is this a permanent transcendental shift for the brain? My second question : how pictorial space observation is helpful for ADHD? Is this has any relation with Vision + Mental Ailments? My third question is : How Vision Science and Synesthesia are connected together ? Monocular and binocular stereopsis are normal for synestetics?
Sateda: Holograms stimulate the visual senses and apparently reveal fascinating dimensions of thoughts and emotions, awakening dormant layers in the cortex system.I am very much interested to know more about Kind of thoughts ,emotions and awakening dormants layers ? Which are they? Specific model of hologram (the vibration sensitivity of holography part of one of the flowers vanished into light) Could we connect this with the mind in a constructive manner or in a destructive manner? .As an artist I realized that an art work could work as a weapon/Energy system/ healing stuff?
Celestis: @OP, Thank you for sharing!
