Wielowątkowość jest postrzegana jako trudne zadanie do wdrożenia i nie jest w pełni rozwinięta. Programiści często unikają jej, ponieważ do prawidłowego wdrożenia wymaga wiele pracy. Według mnie wynikający z tego wzrost wydajności jest warty tych kosztów. Ponieważ nie ma wielu silników gier, które w pełni wykorzystują wielowątkowość, celem tej pracy jest zaprojektowanie i zaproponowanie wielowątkowej architektury silnika gry 3D, a także przedstawienie głównych systemów używanych do stworzenia takiego silnika gry 3D. Praca skupia się na technologii i architekturze silnika gry i jego podsystemach wraz ze strukturami danych i algorytmami wykorzystywanymi do ich stworzenia. -

The Pennsylvania State University The Graduate School College of Communications EVALUATIO OF FOSS VIDEO GAMES I COMPARISO TO THEIR COMMERCIAL COUTERPARTS A Thesis in Media Studies By Jesse A. Clark © 2008 Jesse A. Clark Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Arts August 2008 ii The thesis of Jesse A. Clark was reviewed and approved* by the following:: John Nichols Professor of Communications Associate Dean for Graduate Studies and Research Matt Jackson Associate Professor of Communications Head of Department of Telecommunications Thesis Advisor Robert Frieden Professor; Pioneers Chair in Telecommunications Ronald Bettig Associate Professor of Communications *Signatures are on file in the Graduate School. iii Abstract The topic of copyrights and copyright law is a crucial component in understanding today's media landscape. The purpose for having a copyright system as outlined in the U.S. Constitution is to provide content creators with an incentive to create. The copyright system allows revenue to be generated through sales of copies of works; thus allowing for works to be created which otherwise would not be created. Yet it is entirely possible that not all large creative projects require the same legal framework as an incentive. The so called “copyleft” movement (which will be defined and explained in depth later) offers an alternative to the industrial mode of cultural production. Superficially, “copylefted” works can be divided into two broad categories: artistic/creative works (which are often protected by “Creative Commons” licenses), and Free/Open Source Software. This thesis evaluates how open source video games compare to their commercial counterparts and discusses the reasons for any difference in overall quality. -

JOURNAL FOR TRANSCULTURAL PRESENCES & DIACHRONIC IDENTITIES FROM ANTIQUITY TO DATE THERSITES 7/2018 www.thersites.uni-mainz.de CHRISTIAN ROLLINGER (Universität Trier) Battling the Gods An Interview with the Creators of “Apotheon” (2015): Jesse McGibney (Creative Director), Maciej Paprocki (Classical Scholar), Marios Aristopoulos (Composer) in: thersites 7 (2018), 11-29. KEYWORDS Game Studies, Game design, Ancient Mythology, Music design Christian Rollinger Introduction In 2015, Alientrap Games, a small, independent game studio based in To- ronto, released the video game Apotheon for Windows/PC, Mac OS X, Linux, and PlayStation 4. Apotheon is a visually striking side-scrolling ac- tion-adventure game, in which the player takes on the role of an ancient Greek hero fighting against Olympian deities.1 As Nikandreos, his mission is to wrest divine powers from the Gods, in the process becoming a deity himself. The game has received generally favourable reviews and holds an aggregated Metacritic score of 78/100.2 Reviews have lauded the game for its ‘old school’ appeal, being a classic scrolling action title in a time that almost exclusively focuses on 3D action games in the God of War vein.3 While reviews of the game were not universally favourable, with some crit- icising the game’s inventory system and combat modes,4 the distinctive graphics, inspired by Greek vase paintings, and soundtrack have garnered widespread applause, and reviewers praise the game’s “stunning look and feel”5, stating that playing Apotheon “is like being an archaeologist explor- ing and unearthing the mysteries of an unknown world. […] Like the ochre- stained walls of an Athenian temple circa 500 BC, Apotheon’s characters are little more than black silhouettes.”6 1 http://www.alientrap.com/presskit/sheet.php?p=apotheon (accessed 18.09.2018). -
