Our method focuses on removing the weaknesses of the original approach by simplifying and fusing different phases, while replacing most performance critical parts by novel and more efficient algorithms. This combination allows for outperforming the original approach by a factor of 1.9 - 2.3×.CCS Concepts: Computing methodologies -> Ray tracing Additional Key Words and Phrases: bounding volume hierarchy, ray tracingComputing methodologiesRay tracing Additional Key Words and Phrasesbounding volume hierarchyray tracing10.1145/3543867
