A ray tracing apparatus includes a ray generator and a traversal (TRV)/intersection test (IST) integrator. The ray generator is configured to generate a ray. The TRV/IST integrator is configured to receive the ray, determine one of a ray-node intersection test, an intersection distance test, and a hit point test to be performed based on a state of the ray input thereto, and perform the determined test with respect to the ray. The ray-node intersection test, the intersection distance test, and the hit point test are performed with respect to the ray through same pipeline.
