Abstract: A method and system for traversing a bounding volume hierarchy (BVH) structure associated with a given 3D scene using a ray tracing algorithm are provided. The method comprises: determining an escape probability value for a given node of the BVH structure of a given ray traversing the given node without reflecting off any mesh element contained therein; propagating a ray in the given 3D scene that intersects the respective bounding volume of the given node; in response to determining that the ray is to traverse the respective bounding volume, determining whether the ray is to traverse or to reflect off an other respective bounding volume; and in response to determining that the ray is to reflect off the respective bounding volume: rendering a mesh element contained in the respective bounding volume of the given BVH node.
