Abstract - VR is an emerging technology in which people engage with a simulated 3D environment. VR has grown rapidly; its success hinges on using advanced computer graphics methods to produce high-quality visual output in real-time. However, producing both visually realistic output and high-performance output is significantly challenging due to the requirement for high frame rates (60 frames per second or more), low latency, as well as real-time responsiveness. All of these criteria must be met to provide seamless interaction and avoid adverse side effects such as motion sickness. The present paper provides a comprehensive overview of the recent advancements related to computer graphics for use in VR applications between 2023-2025.
The overview addresses how addition of new computer graphic rendering methods including Foveated Rendering (where detail density is concentrated in the region where the user is visually directing their gaze), Neural Rendering (utilization of machine learning models to create very realistic scenes), and Real-Time Rate Tracing (real time lighting and advanced visual effects) all contribute to the advancement of computer graphics for VR applications. Also described herein are the use of remote resources such as cloud computing and edge rendering to offload the burden of computation away from VR user’s local machine to produce increased productivity benefits. Further, this paper discusses many important optimization techniques including reduced latency; Adaptive Rendering; and Memory Management strategies.
These methods play a crucial role in balancing rendering quality with system performance. The review also identifies key challenges such as handling complex scenes, maintaining synchronization, and achieving scalability across different devices.
Overall, this paper provides insights into the current state of VR graphics technologies and outlines future directions for developing more efficient, scalable, and immersive virtual reality systems.
