초록

본 연구에서는 Unity 3D에 적용 가능한 최적화 방안을 조사하고 실험을 통해 최적화가 적용된 콘텐츠의 효율성을 평가하였다. 그리고 이를 적용하여 우주를 배경으로 한 생존을 주제로 하는 가상현실 콘텐츠를 제작하였다. 해당 실험에서는 가상현실 우주 생존 콘텐츠를 Android OS 플랫폼으로 빌드한 뒤, Unity Profiler를 활용하여 CPU 처리 속도, 총 메모리 사용량, 드로우콜, FPS를 측정하고, 최적화 기술 적용 전후의 성능을 비교하여 표로 나타내었다. 그 결과 본 연구에서 제안하고 있는 '라이트 베이크', '오클루전 컬링', '오브젝트 풀링', 'JSON을 활용한 비동기적씬 로딩' VR 기기에서 3D 콘텐츠 최적화 방안이 매우 효율적인 것을 알 수 있었다. 본 연구는 VR 기기에서 활용될 3D 콘텐츠 개발의 고질적인 문제인 최적화 문제를 Unity 엔진에서 간편하게 해결할 수 있는 방안을 제안함으로써 인디 게임 개발자나 Unity 엔진에 익숙하지 않은 사람들이 VR 콘텐츠를 개발할 때 유용한 가이드라인으로 활용될 것을 기대한다.

In this study, we investigated optimization methods applicable to Unity 3D and evaluated the efficienc y of optimized content through experiments. And by applying this, we created virtual reality content with the th eme of survival set in space. In this experiment, virtual reality space survival content was built on the Android OS platform, and CPU processing speed, total memory usage, draw call, and FPS were measured using Unity P rofiler, and the performance before and after applying the optimization technology was compared and presented i n a table. . As a result, it was found that the 3D content optimization methods proposed in this study, includin g 'Lighting Baking', 'Occlusion Culling', 'Object Pooling', and 'Asynchronous Scene Loading Using JSON', wer e very efficient in VR devices. This study proposes a way to easily solve the optimization problem, which is a chronic problem in the development of 3D content to be used in VR devices, in the Unity engine, providing a useful guideline for indie game developers or people unfamiliar with the Unity engine when developing VR con tent. I hope it will be used.
