Effect of rendering space on the performance of the ray marching method

This study delves into exploring the efficiency of rendering implicit surfaces through two distinct methodologies: screen rendering space and bounding volumes rendering space. By conducting a thorough analysis, visualizing rendering differences, and conducting performance assessments, we aim to evaluate the effectiveness of each approach. Our findings illuminate significant advantages offered by bounding volumes rendering space. These advantages include the effective elimination of empty areas, a reduction in ray marching iterations, and optimized CPU and GPU resource utilization. Notably, bounding volumes rendering space showcases an 87% increase in average framerate compared to screen rendering space. Specifically, it achieves an average of 102.71 FPS, in contrast to the 54.82 FPS achieved by screen rendering space. These results underscore the potential of bounding volumes rendering space as a potent strategy for enhancing rendering efficiency in ray marching-based implicit surface visualization. We advocate for its integration into rendering pipelines and propose avenues for future research to further maximize its benefits and influence in the realm of computer graphics and visualization.
