Efficiency Evaluation for Triangle/Ray Intersection Algorithms on Hardware

Ray Tracing is one of the most popular graphics algorithms due to its realism. The algorithm has a high computational complexity, which makes it impossible to implement in real time until today. The Triangle/Ray intersection is an specific problem, which has several implementation options, including the barycentric transformation. The state of the art diverges respect to the efficiency of the barycentric transformation compared against other algorithms. This research addresses the problem from a theoretical implementation point of view, demonstrating an efficiency of at least 53% with the barycentric transformation, applicable for any architecture or implementation.
