Ray tracing is an inherent part of photorealistic image synthesis algorithms. The problem of
ray tracing is to find the nearest intersection with a given ray and scene. Although this …

3D particle data is relevant for a wide range of scientific domains, from molecular dynamics
to astrophysics. Simulations in these domains can produce datasets containing millions or …

Modern Graphics Processing Units (GPUs) have evolved to high performance general
purpose processors, forming an alternative to CPUs. However, programming them …

Memory performance is a crucial bottleneck in many GPGPU applications, making
optimizations for hardware and software mandatory. While hardware vendors already use …

Abstract Incremental encoding of Bounding Volume Hierarchies (BVH) enables coarse
quantization of bounding volumes, significantly reducing their memory footprint. However …

Triangular grid primitives are a technique used to handle memory-intensive meshes more
efficiently. They are also referred to as micro meshes in recent proprietary hardware …

High-level programming models such as OpenMP and OpenACC are used to accelerate
loop-parallelizable applications. In such applications, a very large number of loop iterations …

Blind separation of communication signals invariably relies on some form (s) of diversity to
overdetermine the problem and thereby recover the signals of interest. More often than not …

Ray tracing is a fundamental rendering technique that typically projects three-dimensional
representations of a scene onto a two-dimensional display. This is achieved by …

Ray tracing is an important computational primitive used in different algorithms including
collision detection, line-of-sight computations, ray tracing-based sound propagation, and …
