A KD-trees based method for fast radiation source representation for virtual reality dosimetry applications in nuclear safeguards and security

In order to achieve this target the authors have been working in ways of improving the efficiency of the Point-Kernel method by reducing its computational effort. This paper presents the latest step in this pursuit of efficiency; a novel method based on a non-regular kernel approach, combined with a KD-tree based volume division method. Devised to reduce as much as possible the number of points that represent the volume of the source while aiming at retaining sufficient dose computation accuracy.
