Researches from Japan have created display card HORN-6 that allows computer calculation of 3D holographic image, as informed by Ars Technica.

The display card consists of four programmable matrixes FPGA that contain about 7 million solid-state logical rectifying elements. Each matrix is connected with 256 MB ram memory. The fifth smaller FPGA controls data transfer through PCI interface.

With a help of ray tracing technology scientists have learned to calculate a holographic pattern with 1920х1080 pixel resolution (Full HD) in real time mode. With a laser ray researches have created a 3D image of meter dimensions.

The given technology is far from being perfect. The HORN-6 card requires 12.5 sec in order to calculate one snap. The scientists demonstrated a claster of four computers, in each of them four display cards are installed. This system allows image change with frequency of 1 snap/min.

The researches compared performance of a new display card with characteristics of the processor Intel Pentium IV frequency 3,4 GHz. The processor required more than 1 hour and a quarter in order to calculate 1 3D snap. The card HORN-6 calculates 360 snaps at the same time.
