Lambda Research Corp.’s TracePro 7.0 optomechanical design software increases ray tracing speeds by up to 10 times over the company’s 6.0 version using new multithreading algorithms. The 3-D computer-aided design release also features a new interactive optimizer, a rearrangeable system tree, new RepTile geometries and irradiance options. It uses multithreaded algorithms to ray trace on all the cores in Intel Corp. or AMD Inc.’s multicore central processing units. Simulations done on a dual-quad core computer show ray tracing speed improvement when simulating LED, lighting, display, biomedical and aerospace systems. The optimizer is configured for nonsequential design on LED and illumination systems.
