Real-Time Rendering: A Comprehensive Review of Techniques and Application Domains

Real- time rendering is one of the core technologies in computer graphics which allows for visualization on a display device by producing images at a fast rate. This paper reviews five key research papers which have played an essential role in advancing rendering technology. The selected articles provide insights into the current classification of various render ing techniques ranging from basic classifications of rendering methods up to GPU acceleration and ray-tracing techniques currently utilized in game developing, VR, and simulations. Rendering techniques considered in these papers include geometric rendering, image-based rendering, global illumination, shadow mapping and real- time ray tracing techniques. Advances in the field of hardware, especially graphics processing units, and dedicated graphic systems allow implementing complex shading and lighting models that improve realism. Some of these improvements are described in this paper. Other topics related to rendering techniques covered in this work include optimization techniques, combination of techniques, and integration of artificial intelligence based techniques. Based on comparative analysis, this study indicates that currently, hybrid rendering techniques that combine rasterization and ray tracing techniques are the most promising areas. Several problems associated with rendering techniques are described in this study. Finally, some possible directions of further research are highlighted.
