Parallel computing using accelerators has gained widespread research attention in the past few years. In particular, using GPUs for general purpose computing has brought forth several success stories with respect to time taken, cost, power, and other metrics. However, accelerator based computing has significantly relegated the role of CPUs in computation.(More)
Ray Casting is an important visual application, used to visualize 3D datasets, such as CT data used in medical imaging. High quality image generation algorithms, known as ray casting, cast rays through the volume, performing compositing of each voxel into a corresponding pixel, based on voxel opacity and color. Since all rays perform the computations(More)
