For ray tracing scenes composed of primitives, systems and methods-accelerate ray/primitive intersection identification by testing rays against elements of geometry acceleration data (GAD) in a parallelized intersection testing resource. Groups of rays can be described as shared attribute information and individual ray data for ray data transfer. A host hosts shading and/or management processes can control the testing resource and adapting the ray tracing. The GAD elements can be arranged in a graph, and rays collected into collections based on whether a ray intersects a given element. When a collection is deemed ready for further testing, it is tested for intersection with GAD elements connected, in the graph, to the given element. The graph can be hierarchical such that rays of a given collection are tested against children of the GAD element associated with the given collection.
