BIO

ABOUT ME

I received the B.Sc. degree in Computer Science and M.Sc. degree in Computer Science from the University of Jaén in 2019 and 2020, respectively. I was the recipient of a doctoral grant from the Spanish Ministry of Science, Innovation and Universities in 2020 (FPU19). I am currently a Predoctoral Fellow and Assistant Professor at the University of Jaén. My research interests include fields in computer graphics such as GPU computing, rendering techniques, geometric algorithms and image processing, as well as the fusion and applications of Remote Sensing data from real-world environments. I was also the recipient of the Award of Best Bachelor Thesis in 2019 and Best Master Thesis in 2021, by the Center for Advanced Studies in Information and Communication Technologies (CEATIC). In 2022 I was awarded with the Best Academic Curriculum in M.Sc. degree in Computer Science at the University of Jaén.

Large Point Cloud Rendering

Large Point Cloud Rendering

Framework for the rendering of large point clouds using GPU compute shaders instead of the traditional rendering pipeline. The size of the point clouds is limited by the memory capacity of the GPU, as they are fully loaded into the GPU, either as a single buffer or several chunks. The benefits of this framework are presented in a Conference paper entitled "Comparison of GPU-based methods for handling point cloud occlusion", where sorting algorithms are omitted, though they allow reducing the response time up to the half of the reported results. For that purpose, points are sorted along a Z-curve to place close points in similar buffer indices. This methodology is also used for providing a reduction tool, in order to decrease the number of points (mainly for large point clouds which cannot be fully wrapped in the GPU).

Some screenshots from the rendering tool are following attached:
