Inventing and Re-Inventing the Perception of Color
No full textDeveloped within the PERCEIVE project, the Color Science Demonstrators exemplify a research-driven approach to rethinking how color is perceived, interpreted, and communicated through contemporary technologies. These artistic-technical prototypes translate complex scientific concepts and historical research into immersive, accessible experiences. Designed to engage both expert and public audiences, they serve as critical tools for exploring the intersection of digital innovation and cultural heritage. Each demonstrator corresponds to one of the five core scenarios in the PERCEIVE project- polychrome sculpture, painting, textiles, historical photography, and born-digital art-and reflects a distinct dimension of the project's inquiry, ranging from restoration science and digital heritage to immersive design and reinterpretation of historical narratives. Together, they transform abstract theoretical investigations into tangible, experiential formats. Each of the Color Science Demonstrators embodies a specific scenario from the PERCEIVE project, transforming scholarly inquiry into immersive experience. The Autochrome Demonstrator, addressing historical photography, visualizes early color processes through layered physical components and AI-generated reconstructions, raising questions about authenticity and restoration. The SCREAM Demonstrator, linked to painting, translates color diNerences in versions of Munch's The Scream into a topographic surface animated by light and sound, evoking an emotional and spatial reading of color. The VR CHROMA installation, tied to the born-digital art scenario, oNers a virtual exploration of the Chroma Tower and augmented artworks, positioning color as both symbolic and architectural within a navigable digital landscape. Lastly, the Gabinetto Segreto Demonstrator, referencing polychrome sculpture, abstracts the historical Roman cabinet into a compact illuminated form that channels the sensuality and mythology of antiquity through light-based projection and reinterpretation. By addressing distinct material and conceptual challenges in color conservation and representation, the Color Science Demonstrators not only showcase the technological and theoretical advances of the PERCEIVE project but also invite deeper public reflection on how color functions as both a perceptual phenomenon and a bearer of cultural meaning. Whether by evoking emotion, reconstructing historical processes, or imagining future interactions with digital art, these demonstrators challenge traditional modes of museum engagement and point toward new, inclusive models of cultural experience. They propose a forward-thinking approach to color-at once scientific, artistic, and profoundly human.Digital HeritagePoster

Evaluating Zero-Shot Monocular Depth Estimation Models for Tactile Rendering of Paintings
No full textAccess to pictorial art remains a significant challenge for visually impaired individuals, as 2D paintings require transformation into tactile 2.5D/3D models. While deep learning offers promising tools for monocular depth estimation (MDE), applying state-of-the-art zero-shot models to artworks presents unique difficulties due to artistic conventions (perspective, lighting, texture) and the lack of ground truth, especially concerning details crucial for tactile perception. This paper addresses this gap by qualitatively evaluating a wide range of SOTA zero-shot MDE models - including DepthAnything (v1/v2), Marigold, Metric3D v2, ZoeDepth, UniDepth (v1/v2/v2_old), GeoWizard (v1/v2), and Depth-Pro - on their ability to generate depth maps suitable for tactile rendering from two 20th-century Italian paintings with distinct styles and input qualities. The assessment, based on criteria like detail preservation, contour definition, spatial coherence, and artifact absence, reveals that while zero-shot models can interpret basic spatial structures, performance varies considerably. Models such as DepthAnything v2 and GeoWizard v2 demonstrated superior capabilities in preserving key features for tactile fruition, emerging as promising candidates. However, no model produced a directly usable output, highlighting persistent challenges in handling artistic styles and pictorial textures. This study provides the first systematic comparison in this niche application, offering practical insights for cultural institutions aiming to leverage AI for accessibility. It concludes that current zero-shot models, while valuable starting points requiring validation and refinement, show significant potential but also underscore the need for further research in areas like targeted post-processing, art-specific metrics, and user-centered validation to make cultural heritage truly accessible to all.Digital HeritageDigital Technologies for CHANGES (CHANGES SESSION) - Part
Inflecting Data Visualizations for Web-based Scrollytelling
No full textWe propose the idea of inflections as a method for capturing and conveying interpretative interactions with data visualizations. Aiming to narrow the gap between data analysis and story authoring, inflections are subtle modulations of a visualization's graphical attributes that guide attention, highlight important patterns, and embed communicative cues. By parameterizing view changes and annotations in visualizations, authors can embed insights from their data analysis into story segments and connect them with the respective visualization states. This paper presents the general concept and a technical architecture supporting inflectable data visualizations. By leveraging native web technologies and established visualization conventions, we propose a flexible and extensible approach to inflecting visualizations that link exploratory data analysis and data-driven storytelling.EuroVis 2025 - Short PapersTechniques and Tool
A lightweight open-source tool for Meshing within Geosciences
No full textUnderstanding and modeling the complex geometries of the natural world is a key challenge in the Geosciences. Representing terrains, subsurfaces, catchments, and environmental domains requires not only accurate data acquisition but also robust and flexible geometric modeling tools. While computer graphics and geometry processing have made significant advances in representing and manipulating complex 2D and 3D shapes, their uptake in environmental modeling remains limited due to the lack of geoscientific constraints and interoperability with geospatial standards. We present MUSE-geometry, a lightweight computational geometry tool designed to bridge this gap. Our tool integrates geometric primitives, structured and unstructured meshing, and editing operations with explicit support for geospatial data formats and coordinate reference systems. By combining computational geometry with geospatial awareness, the tool enables the creation of simulation-ready 2D/3D models that preserve input integrity and topological consistency. Implemented as a selfcontained command-line application in C++, our tool has been tested on real-world scenarios, including modeling topographic surfaces or coastal water volumes, demonstrating its ability to unify data structures and geometric processing within a single pipeline. The tool offers flexible and interoperable operations that enhance the integration of advanced geometric processing into geoscientific workflows in compliance with geospatial standards.Smart Tools and Applications in Graphics - Eurographics Italian Chapter ConferenceTools in Computer Graphic
Topographic Lifeline Maps
No full textWe introduce Topographic Lifeline Maps (TLMs), a visualization technique that combines a network of lifelines with topographic time maps to present genealogical graphs with both temporal detail and structural clarity. In TLMs, each individual's life is represented as a continuous curve that encodes birth, life events, and death in chronological order, while couples are depicted as parallel, merged lifelines. The layout is computed by a hybrid force model combining repulsion, temporally scaled springs, curvature-straightening, and octilinearization forces. Temporal interpretability is further enhanced through age-aware color encodings, with uncertain or missing dates distinguished visually to guide genealogical research. We demonstrate the expressiveness of TLMs on a large real-world dataset, illustrating diverse family stories, lifespans, and relational structures. A comparative user study against Topographic Attribute Maps (TAMs) shows that, while task performance is similar, participants consistently find TLMs more helpful across all analysis tasks. Our results highlight how mathematical layout formulations can advance genealogical visualization and suggest broader applicability to temporal-relational data beyond genealogy.Smart Tools and Applications in Graphics - Eurographics Italian Chapter ConferenceTools in Computer Graphic

Real-time Level-of-detail Strand-based Rendering
No full textWe present a real-time strand-based rendering framework that ensures seamless transitions between different level-of-detail (LoD) while maintaining a consistent appearance. We first introduce an aggregated BCSDF model to accurately capture both single and multiple scattering within the cluster for hairs and fibers. Building upon this, we further introduce a LoD framework for hair rendering that dynamically, adaptively, and independently replaces clusters of individual hairs with thick strands based on their projected screen widths. Through tests on diverse hairstyles with various hair colors and animation, as well as knit patches, our framework closely replicates the appearance of multiple-scattered full geometries at various viewing distances, achieving up to a 13× speedup.Computer Graphics ForumReal-Time Rendering44
ESILab: An efficient software for immersion and exploitation of large point clouds
No full textDigitization techniques now makes it possible to produce precise and dense textured 3D point clouds. Therefore, 3D surveys of monuments or archaeological sites can easily reach several billions of points. To ensure a smooth virtual visit and to manipulate these point clouds, we have developed the ESILab software (Enhanced Scan Immersion Lab). Thanks to a dedicated 3D model converter using an octree partitioning of the point cloud and the accessibility of rendering engine parameters, ESILab can load a 3D model containing several billion points in just a few seconds. It also makes it possible to load multiple point clouds, superimpose them and extract slices for relevant comparisons and visualizations. The point clouds of six famous and very large French Gothic monuments were used simultaneously to demonstrate the software's potential (see the attached video to the paper). This software can be shared free of charge upon request right now and will be made available to the public as soon as possible.Digital HeritageDigitization and 3D Visualization for Heritage Accessibilit
