“…For example our warping operator could be used to describe the aberrometry data of a human eye, produced from a Shack-Hartmann device [Platt and Shack 1971;Barsky et al 2002]. The warped rays would sample from an acquired light field, presenting photorealistic interactive scenes as seen through a human optical system.…”

Light fields can be used to represent an object's appearance with a high degree of realism. However, unlike their geometric counterparts, these image-based representations lack user control for manipulating them. We present a system that allows a user to interactively manipulate, composite and render multiple light fields. LightShop is a modular system consisting of three parts: 1) a set of functions that allow a user to model a scene containing multiple light fields, 2) a ray-shading language that describes how an image should be constructed from a set of light fields, and 3) a real-time light field rendering system in OpenGL that can plug into existing 3D engines as a GLSL shader.We show applications in digital photography and we demonstrate how to integrate light fields into a modern space-flight game using LightShop.

Traditional computer graphics methods render images that appear sharp at all depths. Adding blur can add realism to a scene, provide a sense of scale, and draw a viewerÕs attention to a particular region of a scene. Our image-based blur algorithm needs to distinguish whether a portion of an image is either from a single object or is part of more than one object. This motivates two approaches to identify objects after an image has been rendered. We illustrate how these techniques can be used in conjunction with our image space method to add blur to a scene.

“…Vision-realistic rendering is introduced by Barsky et al in a poster at Eurographics 2002 [8], and the details can be referred to in [9], which presents synthetic images showing the characteristics of a particular individual's optical system. Several depth images are created and blurred according to the input image and corresponding depth map.…”

Abstract-Human eyes are not perfect optical systems, most of them have refractive errors, the simulation of which is a plus to the realistic vision rendering. This paper presents the simulation of the properties of human eye optical system with an abstracted human eye optical model, including myopia, hyperopia and astigmatism. A novel and effective ray-tracing-based method is brought out in this paper, which calculates the direction of rays refracted by the eye without modeling the surface of the crystalline lens. In order to achieve better simulation results, a circinate-patterned sampling method is proposed, which covers most of the radiation angles and has a distribution similar to Gaussian distribution. The variation of depth of field accompanied by the adjustment of the pupil size in reaction to the luminance of the environment is also simulated.Index Terms-Ray tracing, myopia, hyperopia, astigmatism, depth of field, human eye optical system.
