시각적 오류 문제를 경감하는 Oculus Rift 기반 3D 입체 게임 구현

Abstract

In this paper, we define four problems that cause visual artifacts when implementing a stereoscopic 3Dgame using Oculus Rift which supports head tracking, and then we provide its solutions. For the firstproblem that the center point of the camera deviates when the headset rotates over a certain angle (180degree), the game character body was rotated further by the offset that exceeds a certain angle. Theproblem of the disharmony of color images was also solved by limiting the color tones of the color palette. Plus the response time problem of the head tracking was solved by applying the ease-in-out Bezier curveanimation to camera movement. Finally the visual artifacts problem in 2D user interface (UI) was solvedby placing 3D UI outside the Oculus Rift camera. Therefore, this paper provides the Oculus Rift basedimmersive stereoscopic 3D game development methodology.
