Various rendering techniques often use different approaches to the same aspects of the image synthesis process, mainly due to their complexity and constant development. Excluding global illumination algorithms, appearance descriptions are key distinguishing factors between the rendering systems. These descriptions might include BRDF models, support for spectral color representation, and even integration of advanced phenomena, such as fluores- cence. Unfortunately, as there are no standardized implementations of these features, their computations might not be completely accurate, which may result in their incorrect representation. This thesis describes an evaluation suite that methodically tests rendering algorithms based on their appearance reproduction capabilities. The core of the suite is a set of scenes that test five specific appearance phenomena - polarization, GGX reflectance, fluorescence, iridescence and the overall spectral accuracy. Each test case scenario contains as few scenes as possible while maximizing the number of covered aspects of the tested feature. For the user's convenience, we wrap the scenes inside an automatic workflow that runs the specified test case scenarios and displays the results. As a correctness metric, we provide manually verified reference images that are considered to...

Syftet med studien var att kvantitativt undersöka förekomsten av negativ kroppsuppfattning samt sambandet mellan negativ kroppsuppfattning och psykisk ohälsa hos unga män. Frågeställningarna var hur vanligt det var med negativ kroppsuppfattning hos unga män på gymnasieskolor i södra Sverige, samt om det fanns ett samband mellan negativ kroppsuppfattning och psykisk ohälsa hos samma målgrupp. Urvalet bestod av 116 deltagare ( M = 17 år), vilka besvarade en enkät där negativ kroppsuppfattning och psykisk ohälsa mättes med hjälp av mätinstrumenten Appearance Evaluation respektive Global Health Questionnaire 12 . Resultaten visade att 23 % av deltagarna hade en negativ kroppsuppfattning, och att det fanns ett signifikant samband med medium effektstorlek mellan negativ kroppsuppfattning och psykisk ohälsa. Slutsatsen blev att negativ kroppsuppfattning förekom hos unga män på gymnasieskolor i södra Sverige, samt att det fanns ett samband mellan negativ kroppsuppfattning och psykisk ohälsa hos de unga männen. Emellertid bidrog metodologiska svårigheter till att resultaten inte är generaliserbara. / The purpose of this study was to quantitatively investigate the prevalence of negative body image and the correlation between negative body image and psychological distress in young men. The research questions were how common negative body image was in young men in high schools in southern Sweden, and if negative body image correlated with psychological distress within the target group. The sample consisted of 116 participants ( M = 17 years), who answered a survey where negative body image and psychological distress was measured by Appearance Evaluation and General Health Questionnaire 12. Results showed that 23 % of the participants had a negative body image, and that there was a significant correlation with medium effect size between negative body image and psychological distress. The conclusion was that negative body image existed in young men in high schools in southern Sweden, and that there was a correlation between negative body image and psychological distress among these young men. However, the methodological difficulties contributed to the results not being generalizable.
