This article makes a case for sex-positive research and pedagogy that acknowledges and hence reflects on the researcher's use of a "pornographic mirror," a critical and consensual engagement with erotic and pornographic (self-)imagery that opens up bodily sensations and analysis in the public sphere. The article will do so by means of examples of research in which scholars were able to successfully test out such corporeal-driven scholarship and use of porn images. In the first example, the author interviewed an older generation of sex educators in San Francisco, who in the 1960s/1970s pioneered the idea that students could perform and analyze their own sexual behaviors by acting in, and reflecting on, sexually explicit movies, an idea which has also been incorporated into contemporary feminist and queer pornography. This historical moment in radical pedagogy is extended into a contemporary example of sex-positive research about online dating, in which the author comments on her use of sex chat and sexual self-imagery to dissect the online dating site adultfriendfinder.com.

This essay discusses methods of pedagogy and educational philosophy stirred up by the Hong Kong Umbrella Movement/Occupy-Hong Kong Movement at the end of 2014. It situates these events as a way to envision a new type of public university. To this end, the essay proposes a model of 'wandering scholarship,' in which educators and activists walk through urban environments and use dialogic esthetics to reclaim them as 'Commons.' Wandering means a multisensory exploration and learning based on the historical concept of 'psychogeography,' a drifting through sites and interpellation of their embedded ideologies. As opposed to traditions of introspective wandering, this kind of 'dialogic wandering' is done within groups and encourages people to talk to fellow-walkers or random bystanders. As will be shown, these modes of wandering while addressing publics were pioneered in the 1960s student movements and also adopted in a unique manner by the young activists of the Umbrella Movement. Dialogic wandering leads to affective languages and embodied learning as opposed to modes of analytical reasoning and logic within higher education. To further study the impact of this aspect of social movements within a university curriculum, it will be shown by means of example how students can meaningfully adopt dialogic wandering to survey people's affect and ideological positioning within environments.

The author talks about queer sexuality in historical ghost fictions and films by referring to her short film and video installation, "The Ghost of Sister Ping" set in contemporary Hong Kong, China. Topics discussed include research on sexually explicit art and media in China, the film "Rouge" directed by Stanley Kwan, the book "The Phantom Heroine: Ghosts and Gender in 17th-Century Chinese Literature" by Judith Zeitlin, and sex as the motivation behind spiritual enlightenment.

The essay contributes to Cultural Studies as an evaluation of changing practices of media and social activism while highlighting theories of feminism and dialogic aesthetics. More specifically, it discusses women’s use of online self-photography as a protest medium and a platform for feminist activism within two distinctive protest movements, the Umbrella Movement of Fall 2014 and the mainland Chinese feminist movement of 2012–2013. Forerunners of these movements in mainland China can be found in the work of performance artists and sex bloggers such as Ye Haiyan and Muzimei, who have used bulletin board systems and blogs to lay bare their sex lives and the cultural mechanisms of misogyny. Their performances in public spaces and their online postings have also elicited public brawls and significant responses within governmental agencies (Farrer, 2007; Tong, 2011).The article posits that these discourses also have a historical lineage in the ‘light’ or ‘fleeting’ dissident writings of the Cultural Revolution that generated large-scale responses but did not aim at becoming earnest or solidified works of art (Voci, 2010). In this vein, nudity is employed to titillate and stir fellow netizens rather than offering a coherent and embodied stance. It offers flippant gestures and statements that come to signify ideology within online social movements. [ABSTRACT FROM AUTHOR]

Relighting algorithms make it possible to take a model of a real-world scene and virtually modify its lighting. Unlike other methods that require controlled conditions, we introduce a new radiance capture method that allows the user to capture parts of the scene under different lighting conditions. A novel calibration method is presented that finds the positions of reflective spheres and their mathematically accurate projection onto the scene geometry. The resulting radiance distribution is used to estimate a diffuse reflectance for each object, computed coherently using the appropriate light probe image. Finally, the scene is relit using a novel illumination pattern. [ABSTRACT FROM AUTHOR]

The article offers information about High-Dynamic Range Image (HDRI) generation which will be used for dynamic scenes. It is said that the method is a success. However, HDRI generation is prone to mistakes in some scenarios. On the other hand, when the Low-Dynamic Range Image capture (LDRI), the scene illumination is modified which is due to cloud movement. Even though the camera alignment is perfect, camera-curve reconstruction will be wrong if conventional camera calibration algorithms. The article also suggested that such movement greatly affects the HDRI generation, however, no proposal in solving the problem has been made.

A mixed reality (MR) represents an environment composed both by real and virtual objects. MR applications are used more and more, for instance in surgery, architecture, cultural heritage, entertainment, etc. For some of these applications it is important to merge the real and virtual elements using consistent illumination. This paper proposes a classification of illumination methods for MR applications that aim at generating a merged environment in which illumination and shadows are consistent. Three different illumination methods can be identified: common illumination, relighting and methods based on inverse illumination. In this paper a classification of the illumination methods for MR is given based on their input requirements: the amount of geometry and radiance known of the real environment. This led us to define four categories of methods that vary depending on the type of geometric model used for representing the real scene, and the sdifferent radiance information available for each point of the real scene. Various methods are described within their category. The classification points out that in general the quality of the illumination interactions increases with the amount of input information available. On the other hand, the accessibility of the method decreases since its pre-processing time increases to gather the extra information. Recent developed techniques managed to compensate unknown data with clever techniques using an iterative algorithm, hardware illumination or recent progress in stereovision. Finally, a review of illumination techniques for MR is given with a discussion on important properties such as the possibility of interactivity or the amount of complexity in the simulated illumination.

This article investigates pornographic web-based media at a time when commercial pornography has flooded the Internet and pockets of sex activism are budding alongside the porn boom. Pornography moving freely across borders is foremost a capitalist vision, but the web's sexual potency is equally defined by web users and artists who visit and maintain peer-to-peer networks for producing and sharing sexually explicit materials. Revisiting Foucault's notion of space as 'heterotopia', networked sexual communication and pornography are shown to permeate physical places and other spaces. Web users cultivate attachments to everyday places and spaces other than the ones they routinely inhabit. Networked sexual agency materializes desire far beyond the confines of community rituals and commodity industries. Besides the fact that porn industries expand their markets and diversify products, sex communities emerge alongside these markets and play a vital role in negotiating sexuality. The article shows how the Internets decentralized mechanisms of power and communication, including debating societies and playgrounds, have entered the realm of online porn and sexuality. Developing a theoretical notion of space as other spaces, the article unfolds the sexual web as exuberant, dispersed in bodies and cultures, yet forcefully regulated by global corporations and nation-state governments.
