Two types of perspective, photographic and visual, are relevant to human vision. Photographic perspective results from the projection of the three-dimensional world on a surface. Photographic perspective has been widely applied in drawings and paintings to create an illusion of depth. Visual perspective is a property of visual space, the space that we, that is, human beings, perceive through vision. Photographs, drawings and paintings are two-dimensional surfaces whereas visual space is a three-dimensional space. The literature on photographic perspective is extensive whereas the literature on visual perspective is scarce. Many questions regarding the perspective nature of visual space are yet unanswered. For example: Does visual perspective develop with age? Does visual perspective depend on the structure of the biotope? Are there cultural differences in how visual perspective is experienced? Is visual perspective represented in animals? What and where is the neural correlate of visual perspective? What has been the influence of visual perspective on the development of visual art? Can visual perspective play a role in computer vision?
