Global Illumination Shadow Layers [PDF]

open access: yesComputer Graphics Forum, 2019
AbstractComputer graphics artists often resort to compositing to rework light effects in a synthetic image without requiring a new render. Shadows are primary subjects of artistic manipulation as they carry important stylistic information while our perception is tolerant with their editing.

Optimization of screen-space directional occlusion algorithms

open access: yesOpen Physics, 2019
Developers of video games and simulations from the day one have been trying to improve visuals of their products. The appearance of the scenes depends to a large extent on the approximation to the physical basis of light behaviour in the environments ...

Global illumination of non-Euclidean spaces [PDF]

open access: yesComputers & Graphics, 2020
This paper presents a path tracer algorithm to compute the global illumination of non-Euclidean manifolds. We use the 3D torus as an example.

Spectrum decomposition in Gaussian scale space for uneven illumination image binarization.

open access: yesPLoS ONE, 2021
Although most images in industrial applications have fewer targets and simple image backgrounds, binarization is still a challenging task, and the corresponding results are usually unsatisfactory because of uneven illumination interference.

Global Illumination-Aware Stylised Shading

open access: yes, 2021
Our aim is to convert an object's appearance to an arbitrary colour considering the light scattering in the entire scene, which is often called the global illumination.

Energy-Reduced Arrhythmia Termination Using Global Photostimulation in Optogenetic Murine Hearts

open access: yesFrontiers in Physiology, 2018
Complex spatiotemporal non-linearity as observed during cardiac arrhythmia strongly correlates with vortex-like excitation wavelengths and tissue characteristics.

Progressive Photon Elimination With a Status Tree

open access: yesIEEE Access, 2020
We describe a modified progressive photon mapping (PPM) method applied with sample elimination, referred to as progressive photon elimination, to pursue accurate results and accelerated iterations.

Parallel hierarchical global illumination [PDF]

open access: yesProceedings. The Sixth IEEE International Symposium on High Performance Distributed Computing (Cat. No.97TB100183), 2002
This paper presents an algorithm that solves the Rendering Equation to any desired accuracy, and can be run in parallel on distributed memory or shared memory computer systems with excellent scaling properties. It appears superior in both speed and physical correctness to recent published methods involving bidirectional ray tracing or hybrid treatments
