Abstract: Highlights•Ray-triangle intersection is crucial operation in modern rendering pipelines.•We propose fast ray-triangle intersection algorithm using early-rejection tests.•Triangle transformations in 2D for efficient early rejection tests are studied.•We compare our algorithm to state-of-the-art ray-triangle intersection algorithms.•Our method achieves watertight results with the pruning approach.
