Research Expertise
Description
My research focuses on Computer Graphics and Visualization, and specialised areas of 3D modelling, animation, rendering, perception and Augmented & Virtual Reality. The central theme in my work is exploring how information is most effectively conveyed through visual digital media, particularly as data complexity increases, display technologies evolve, and these tools become more widely used in fields beyond traditional computer science. My work aspires towards making advanced computer visualisation techniques to interdisciplinary users, and to this end I have collaborated with partners from diverse disciplines include creative arts, psychology, culture heritage, medicine and news media. Recent technological advances have significantly expanded the scale of digital data we process daily, while the fidelity of sensor and display technologies now surpasses the perceptual limits of the human visual system. This presents both challenges and opportunities for research on enriching visual applications to enhance human consumption of data. My work explores how key aspects of static, dynamic, and interactive data can be emphasized to improve human understanding of visual information, enhancing critical details or simplifying where necessary. This optimization serves leisure applications from computer games and digital creativity, to precision-oriented goals, such as scientific and medical analysis. My early PhD and postdoctoral research was amongst the first to apply adaptive detail strategies that use human motion perception to optimise computer generated animations. Later, as PI, I extended this approach to optimizing computer images in general, addressing real-world problems such as the visualization of complex time-varying scientific data, which was integral to my three SFI-funded projects as PI and in my contributions to the Prendergast Challenge award, Life in the Currents. In later years, I further applied these methodologies to nascent areas of research including Augmented Reality and AI-driven techniques for visualisation, featured in my work on the EU-FP7 VERVE and Horizon-EU TRANSMIXR projects.Projects
- Title
- aRTIVVIS: Real-time Time-variant Volume Visualisation
- Summary
- This proposal addresses the problem of real-time interactive visualisation of 3D scientific data, namely volumetric datasets, which are ubiquitous in many application domains such as Medicine, Biology, BioMechanics, Neuroscience, Fluid Dynamics and Veterinary Medicine. Specifically, we deal with the problem of time-variant and multivariate volume data sets which have become more readily available in recent years due to improved scanning technologies and simulation techniques. Such data sets are particularly difficult to deal with due to their computational complexity as well as the information overload that can arise from such visually challenging data. We will employ graphics hardware and parallel computing strategies to address the performance issue, whilst information overload will be dealt with using techniques from perceptually adaptive graphics, computational aesthetics and non-photorealistic rendering which apply smart techniques to improve usability and understandability of data.

- TRANSMIXR - Ignite the Immersive Media Sector by Enabling New Narrative Visions
- Summary
- TRANSMIXR is a collaborative EU project involving 20 partners from industry and academia with the goal of creating novel human-centric tools for remote content production and consumption via social virtual reality. Members of the Graphics and Vision lab at Trinity College Dublin (TCD) are participating in the project by contributing technical expertise and experience in immersive technology, including Extended Reality (XR) development and Volumetric Video understanding. TCD will conduct research in the use of Computer Vision and Graphics techniques for the semantic understanding of Volumetric Video, an emergent digital media format comprising 3D geometry and appearance capture from the real world. Volumetric video has many potential novel applications in the areas of Augmented, Mixed and Virtual reality, for instance in the animation of personalized and photo-realistic 3D holograms of real people. The objective of our work in TRANSMIXR is to improve the quality of volumetric video and increase its ease of deployment and interoperability with other, more traditional, forms of digital media. The team at TCD will also contribute to the consortium's broader activities including the development of a collaborative XR Creation Environment for the application of multimodal Extended Reality in novel uses cases such as the newsrooms and museums of the future or XR applications in performing arts.

- INFOCARVE: Focus and Context Visualisation for Augmented Reality
- Summary
- Leveraging our previous work in interactive 3D visualisation, we propose to develop a system for optimised 3D visualisation overlays in Augmented Reality (AR). The system will provide visualisation functions specific for AR that will be reusable in a number of different application domains. In order to achieve improved visualisation, we employ illustrative rendering techniques (e.g. line drawings) that occupy less screen space, minimally obscuring the real scene. Our previous work has shown that such visualisation can still convey extremely useful information about the shape and structure of virtual objects. In addition we apply user guided techniques to highlight specific parts of the data set important to the user, whilst abstracting extraneous information employing a focus-and context paradigm commonly used in visualisation.

- The Book of Kells: Investigations of style and design through Non-photorealistic Rendering techniques
- Summary
- The project will tackle some long standing problems associated with the style and design of decoration within the Book of Kells through the use of digital media. Employing the methods of non-photorealistic rendering, specific stylistic and design features will be captured and analysed, with the aim of exploring geometrical patterns and compositions, colour palettes and material properties, as well as visceral mood and style. The aim is to place traditional methods of style analysis employed by the art historian on a deeper, more objective and scientific basis. The project will provide an innovative approach to long standing problems, while at the same time giving the Book itself a new and more dynamic relevance in 21st century society. This project will involve developing innovative techniques for the interactive visualisation of digitally scanned imagery from the Book of Kells. Technical contributions will include the segmentation of the imagery into its stylistic components, which will enable the interactive exploration of the images for scholarly academic analysis in particular by art historians. We will develop techniques for generating high-fidelity interactive renderings of the pages of the book, complete with accurate modelling of material and surface properties of the vellum and pigments under varying simulated lighting conditions. Analysis and modelling of the styles, colours and techniques used in the creation of its pages will allow us to develop tools for producing imagery and digital content themed on the book. We will also develop techniques for remote and online exploration of this historical and artistic content in order to facilitate applications that can reach and engage students and the general public.

- Perceptually Optimized Rendering for Dynamic 3D Visualization
- Summary
- This project addresses the problem of interactive/real-time visualization of highly complex dynamic 3D geometric data, including but not limited to high-resolution volumetric data, highly tessellated surface meshes or point-clouds obtained from 3D scanners. In particular, we are concerned with the issue of visualizing dynamic data whilst it undergoes change. Naïve renderings of complex volumetric data often have a tendency to inflict "information overload" on the user due to too much visual data being presented at once, which is exacerbated when the data is dynamic. Our solution will draw on previous research from perception, volume rendering and non-photorealistic rendering (NPR) literature and combine it with previously explored strategies in interaction design (e.g. cutaway/exploded views) towards a system which is perceptually optimized for interactive visualization. One specific implementation goal is to facilitate the visualisation of time-variant volumetric data such as 3D Ultrasound or 4D MRI.

- Interactive 3D Authoring and Non-Photo-realistically Rendered Interfaces
- Summary
- Interactive 3D environments have become ubiquitous in recent years however free-form modelling and authoring detailed environments is still a skill that is reserved for technically-experienced animators and 3D modellers. Using non-traditional interfaces such as sketching tablets, haptic interfaces and simple motion capture coupled with Non-photorealistically rendered views, we seek to make 3D scene authoring and interaction more accessible for a more general class of users, possibly including first time users, children and disabled users.

- Life in the Currents
- Summary
- "Life in the Currents" represents a novel investigation into the role of naturally driven variability in the historical and contemporary exploitation of marine life in the Northeast Atlantic. The project addresses the challenge of assessing the impacts of natural and anthropogenically driven climatic and oceanic variability on marine ecosystems, and the effects of these oceanic changes on terrestrial life and human societies. The outcome of the project is anticipated to resolve intriguing questions, such as how the ocean circulations have an impact on primary biological production and coastal geomorphologies; how does oceanic-riverine interaction affect marine ecosystems (e.g., river flooding as a control of terrestrial nutrient run-off into marine ecosystems); to what degree can variable ocean dynamics explain historical variability in fish catch documented for the past 500-hundred years and how unique are ocean circulation changes within the span of human habitation in Northeast Atlantic?
