Abstract
As a bridge between the virtual world and the real world, real-time rendering technology in computer graphics plays an irreplaceable role in games, film and television special effects, virtual reality and other fields. With the improvement of hardware performance and the expansion of application scenarios, higher requirements are put forward for real-time rendering technology. This study aims to explore the development of real-time rendering technology in computer graphics in recent years, focusing on improving rendering efficiency and visual quality. By analyzing the existing algorithm fr amework and combining the hardware acceleration characteristics, a hybrid rendering scheme based on ray tracing and rasterization is proposed. The scheme uses ray tracing to process complex light and shadow effects and quickly draws geometric models by rasterization. At the same time, machine learning is introduced to optimize the rendering process, such as using neural networks to predict scene visibility to reduce unnecessary computing overhead. This research not only provides a new idea for real-time rendering, but also promotes the progress of computer graphics theory and practice, especially in the field of interactive application, which shows great potential and lays a solid foundation for subsequent related research.
