Developing computer games is a highly specialized process. Adding stereoscopic 3D features to a game can be time consuming an may lead to a whole new production pipeline. While there products like TRIDEF enable stereoscopic 3D gaming on the user side, many leading game manufacturer consider engines with integrated stereoscopic 3D support like the CRYENGINE or the use of a "ready to use" library for adding stereo 3D support to their game. The french company TRIOVIZ has put a new a stereo 3D software development kit on the market, witch works on multiple platforms and can easily be integrated on top of existing game structures. This article addresses what impact the stereo 3D engine has on the game building process. Since stereoscopic 3D computer games will be played on different devices of different sizes with various viewing distances, this article also shows which parameters need to be adapted to provide a comfortable stereoscopic viewing experience for the player.

Requirements for contents service providing a sense of realism based on high quality and high resolution have increased since HD (High definition) and 3D technologies have emerged. Recently, high frame rate (HFR) and multi-channel audio-based contents with 4K resolution have been produced since UHDTV which can display 4 times as many pixels as Full HD on a screen has been released. Also high performance graphic rendering technology using high resolution large display, high-speed transmission technology etc have been continuously researched to improve gamers' level of satisfaction providing greater immersion in game field. The necessity to implement UHDTV game based on high resolution large display has been raised to provide greater immersion and presence. Therefore, the research examines changes in display environment to implement high quality games using UHDTV.

Chroma key technique which composes images by separating an object from its background in specific color has restrictions on color and space. Especially, unlike general chroma key technique, image composition for stereo 3D display requires natural image composition method in 3D space. The thesis attempted to compose images in 3D space using depth keying method which uses depth information of Microsoft Kinect. Object was converted into point cloud type in 3D space after separating it from its background according to depth information. The image in which 3D virtual background and object are composed obtained and played stereo 3D images using a virtual camera. The research showed naturally composed stereo 3D images as well as the feasibility of applying stereoscopic 3D mixed reality image technology.
