Ray tracing survey
WebThis paper presents ray tracing simulations for wave propagation at millimeter-wave frequencies to be applied in future 5G wireless communications. Since attenuation and blockage of millimeter-wave propagation in urban are much more severe than those at microwave frequencies, the line-of-sight rays and non-line-of-sight reflected rays should … WebCombining Ray Tracing with Rasterization : Survey of current strategies and research on hybrid rendering and denoising for real-time rendering.
