Fast shadow casting algorithm in analytical polygon-based computer-generated holography.
Optics Express, 2023 Shadow casting is essential in computer graphics, which can significantly enhance the reality of rendered images. However, shadow casting is rarely studied in polygon-based computer-generated holography (CGH) because state-of-art triangle-based occlusion

A Graphical Framework to Study the Correlation between Geometric Design and Simulation [PDF]
Smart Tools and Applications in Graphics - Eurographics Italian
Chapter Conference 2022, 2021 Partial differential equations can be solved on general polygonal and polyhedral meshes, through Polytopal Element Methods (PEMs). Unfortunately, the relation between geometry and analysis is still unknown and subject to ongoing research in order to identify weaker shape-regularity criteria under which PEMs can reliably work.

Skeletal animation for visualizing dynamic shapes of macromolecules
Journal of Integrative Bioinformatics, 2020 We apply a skeletal animation technique developed for general computer graphics animation to display the dynamic shape of protein molecules. Polygon-based models for macromolecules such as atomic representations, surface models, and protein ribbon models

Computer Animation and Virtual Worlds, Volume 33, Issue 6, November/December 2022., 2022 Stereo window violations in 3D rendering occur when virtual objects in front of a physical screen are clipped at the screen borders. Dynparity introduces a real‐time, per‐vertex, nonuniform projection to eliminate this adversary effect. Our user study shows that Dynparity significantly reduces simulator sickness compared to standard stereo rendering on

Munsell and Ostwald colour spaces: A comparison in the field of hair colouring
Color Research &Application, Volume 48, Issue 1, Page 6-20, January/February 2023., 2023 Left: Partial 3D representations of Ostwald (top) and Munsell (bottom) colour‐order systems. Right and centre: parallel between Munsell colour attributes (Hue, Value, Chroma) and hair colour attributes (nuance, tone, intensity). Abstract Colour science has had a very long history, dotted over the millennia with many contributions from the most diverse ...
