2005 Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia - GRAPHITE '05  
In addition, we show how the crex's flexibility enables it to be incorporated in a predictive framework for time-constrained rendering.  ...  The computational requirements of full global illumination rendering are such that it is still not possible to achieve high-fidelity graphics of very complex scenes in a reasonable time on a single computer  ...  Acknowledgements We would like to thank Peter Apian-Bennewitz and Stefan Jankowski for the library scene.

2021 IEEE Access  
ACKNOWLEDGMENT Many appreciations to Alexandru Naiman for all technical assistance provided.  ...  There are several techniques of real-time global illumination with different degrees of flexibility.  ...  However, a real-time global illumination solution that uses entirely a path-tracing implementation has not proved practical for this generation of GPUs.  ...

Illumination Robust Monocular Direct Visual Odometry for Outdoor Environment Mapping

Xiaolong Wu, Cedric Pradalier
2019 2019 International Conference on Robotics and Automation (ICRA)  
To deal with global and local lighting changes, such as solar flares, the state-of-art illumination invariant photometric costs for RGB-D and stereo SLAM systems are revisited in the context of their monocular  ...  The proposed system is extensively evaluated on the synthetic and real-world datasets regarding accuracy, robustness, and processing time, where our approach outperforms systems with other costs and state-of-art  ...  Illumination Robust Cost Instead of presenting all real-time capable illuminationinvariant formulations suitable for the joint optimization framework, we merely describe the intensity-based method as a  ...

An approximate global illumination system for computer generated films

Eric Tabellion, Arnauld Lamorlette
2008 ACM SIGGRAPH 2008 classes on - SIGGRAPH '08  
Global illumination techniques do not lend themselves easily to flexibility, ease of use, or speed, and have remained out of reach thus far for the vast majority of images generated in this context.  ...  We show that our approach provides an efficient solution, easy to art direct, that allows animators to enhance considerably the quality of images generated for a large category of production work.  ...  We wish to thank PDI/Dreamworks for supporting this work.  ...

GPU-Based Monte-Carlo Volume Raycasting

Christof Rezk Salama
2007 15th Pacific Conference on Computer Graphics and Applications (PG'07)  
We demonstrate our technique being capable of producing convincing images, yet flexible enough for digital productions in practice.  ...  In addition, we propose a simple phenomenological scattering model, closely related to the Phong illumination model that many artists are familiar with.  ...  Hadwiger et al. have proposed a flexible raycasting framework for discrete isosurfaces in large volume data using hierarchical space-leaping and adaptive sampling.  ...

2018 Zenodo  
The FLEXCoop DER load models contain the mathematical formulas for the calculation of electric demand (consumption) of each DER type as a function of dynamic (input data) and static (configuration) parameters  ...  The FLEXCoop load modelling framework will allow for continuous calibration of the respective DER models in order to account for efficient and effective dynamic adaptation to potential shifts in the "behaviour  ...  This approach can be used to reflect real-time dynamic load behaviours and thus, it could be a favourable solution to be adopted in FLEXCoop.  ...

2018 biorxiv/medrxiv   pre-print
New methods for clearing and expansion of biological objects create large, transparent samples that can be rapidly imaged using light-sheet microscopy.  ...  We therefore implemented a flexible framework for the registration of grouped images (Supplementary Note 3).  ...  We extend this concept to affine transformations, introduce a new heuristic that additionally incorporates link quality and implement it in an extendable framework required for the two-round global optimization  ...
