This work implements an optimized CGH computation in their multi-graphics processing unit cluster system, which can calculate a CGH of 6,400×3,072 pixels from a three-dimensional object composed of 2,048 points in 55 ms.Abstract:
To overcome the computational complexity of a computer-generated hologram (CGH), we implement an optimized CGH computation in our multi-graphics processing unit cluster system. Our system can calculate a CGH of 6,400×3,072 pixels from a three-dimensional (3D) object composed of 2,048 points in 55 ms. Furthermore, in the case of a 3D object composed of 4096 points, our system is 553 times faster than a conventional central processing unit (using eight threads).read more
