“…However, computer simulation often has different degrees of approximation. The pictorial environment generated from the computational framework of physically based lighting simulation and perceptually based tone mapping was used earlier to repeat a classic experiment of investigating the size-distance relationship conducted in a physical setting (Tai, 2012). The results obtained were similar to those obtained from the classic experiment.…”

“…In order to examine the manner in which luminance contrast can create illusory depth effects in 3D spaces, Tai (2012) conducted perceptual studies using a computer-generated pictorial environment that allows precise parametric controls. The causal relationship between the architectural configuration, the lighting distribution in the scene, and the perceived distance of a visual target in the scene was established (Tai, 2013).…”

One of the objectives of architectural design is to enrich the spatial experience within the restrictive confines of the architectural space. Various depth cues such as familiar size and linear perspective have been utilized in architectural design to create illusory spatial depth. Luminance contrast has also been identified as an effective depth cue; its effect in increasing depth perception was verified with perceptual studies using a computer-generated environment. However, previous studies have focused on methods for accurate simulation of the lighting distribution in a scene; they have not addressed visual perception with binocular vision. This study utilizes three-dimensional (3D) stereo display technologies to present a perceptually realistic and computer-generated environment. Psychophysical experiments were conducted to examine the impact of luminance contrast in creating illusory depth effects, with scenes presented on both conventional and 3D stereo displays. The objectives of this study are: first, to investigate the influence of binocular vision on the illusory depth effect of luminance contrast; and second, to verify whether a reliable computergenerated environment can be used to envision possible applications of luminance contrast in architectural design.

“…The HDR scenes were tone-mapped by a perceptually based photographic tone-mapping operator [9] to be displayed on a common display device. The visual realism of the final image in terms of studying the depth perception in relation to the lighting has been established in a previous study [10]. Figure 8 illustrates the architectural configuration set up of the experimental scenes.…”

Enriching the spatial experience of an architectural space within its limited structural boundary is one of the goals in architectural design. The manipulation of physical configurations to create a misinterpretation of the depth cue has been found an effective way to create a false perception of the spatial depth in many architectural examples. Luminance contrast has been identified as effective visual information to create an illusory depth effect on a planar surface, and it can cue the relative distance in three-dimensional settings. However, the cause-and-effect relationship between the physical configuration, the luminance contrast, and the resulting spatial experience has not been established yet. In this study, psychophysical experiments were conducted to investigate the relationship between the architectural configuration of skylights, the scene luminance contrast rendered by the daylight that is admitted inside, and the effect on depth perception. Design principles of utilizing luminance contrast through daylighting to enrich the spatial experience of an architectural space were generalized to conclude this study.

Given a set of axis-aligned rectangles in the plane, this paper presents an algorithm for the removal of rectangle containment as well as rectangle enclosures. That is, given a query rectangle R q , this algorithm removes all rectangles R k , . . . , R l from the rectangle set that are contained in R q . It also removes R q if there is a rectangle R j that encloses R q . The algorithm, initially implemented for rectangle spline generation using rectangles as building blocks, is fast, easy to implement and maintain, it can be run on parallel machines such as GPUs at no extra cost, but it requires extra memory to store the rectangle indexes for quick access and space partitioning.
