In this paper, we present a real-time ray caster implemented on GPU using CUDA. It uses a BVH augmented with ropes that is traversed with ray packets to speed up performance. We present two algorithms making use of ray packets, packet-warp and packet-block, which set the packet size to a warp and a block, respectively. We also analyze the influence of the packet size and packet shape by testing several configurations. Finally, we compare the time results we have obtained to previous related papers over a batch of usual scenes.
