    Application of Relational Databases to the Acceleration of Ray Tracing in High Frequency Asymptotic Techniques by David Cabornero, Lorena Lozano, Ivan Gonzalez, Alvaro Somolinos, Felipe Catedra

    “…Compared to traditional techniques that employ Angular Z-Buffer acceleration and store information solely in RAM using a low-level language, this approach decreases memory usage by more than 90% in complex scenarios. …”

    New Ray Tracing Method to Investigate the Various Effects on Wave Propagation in Medical Scenario: An Application of Wireless Body Area Network by M. J. Islam, A. W. Reza, A. S. M. Z. Kausar, H. Ramiah

    Published in The Scientific World Journal (2014-01-01)
    “…The results show that the proposed method is about 1.51, 2.1, and 2.9 times faster than the Object Distribution Technique (ODT), Space Volumetric Partitioning (SVP), and Angular Z-Buffer (AZB) methods, respectively. To show the various effects on received power in 60 GHz frequency, few comparisons are made and it is found that on average −9.44 dBm, −8.23 dBm, and −9.27 dBm received power attenuations should be considered when human, AP, and CU move in a given hospital scenario.…”

    A Novel Algorithm to Estimate Solar Irradiance of Urban Buildings for Photovoltaic Potential Estimation System Using a 3D City Model by R. Matsuoka, T. Takemoto, G. Takahashi, T. Inazawa, S. Sogo

    “…In estimation of solar irradiance distributions on roofs and façades, utilization of projection images viewed from the sun created by using computer graphics (CG) techniques such as the depth buffer (Z-buffer) algorithm makes our system have much less computation time than most of existing systems using a hemispherical viewsheds or ray tracing. …”
