Joint Event: Eurographics Workshop on Material Appearance Modeling (MAM2026) and MANER Conference Bordeaux 2026 (Material Appearance Network for Education and Research), and APPAMAT 2026
Event Co-Chairs: Holly Rushmeier (Yale Univ.), Damien Muselet (Univ. of Saint-Etienne), Romain Pacanowski (Inria, Univ. Bordeaux)
The purpose of this event, which will take place in Bordeaux, France, on June 30, 2026, in conjunction with EGRS 2026 (The 37th Eurographics Symposium on Rendering), is to discuss and define open issues in the acquisition, modeling, perception, and applications of material appearance. In this workshop, we gather researchers and potential users of material appearance models across disciplines and domains, to share recent research and discuss what the major challenges and problems are in this area. One output of the workshop will be a document available through the EG Digital Library (past editions are at http://diglib.eg.org/handle/10.2312/2584) that is intended to help guide future development of material appearance modeling.
As in previous years, the workshop will include short presentations of position papers.
Types of position papers include but are not limited to:
- Acquisition systems
- Perceptual studies of material appearance
- Digital material authoring systems
- Fabrication of material appearance
- New representations of material appearance
- Material appearance in AR/VR/XR
- Applications requiring high fidelity appearance modeling
You may also submit “Appearance Reflections and Extensions”. If you recently published a journal paper (including Eurographics and SIGGRAPH papers) on material appearance and have additional data, information or insights about the work beyond what was presented in the original paper, you are welcome to present these at the workshop. Submit a short abstract summarizing what you will present that augments the original paper.
SUBMISSION
Submissions should be four pages or less in length, using the Style Guide given in this file.
The deadline for submissions is June 2, 2026. Submissions and any questions should be sent via email to the workshop co-chairs: Holly Rushmeier (holly@acm.org). Do not hesitate to drop us a line beforehand about your intention to submit. In special cases, submissions may be reviewed earlier. More information about the event will be available at https://maner.network/.
Keynote Presentation
Material Perception in Artistic Representations
Johanna Delanoy
Correct visual perception of the materials around us is key to our understanding of the world. However, it is not yet fully understood how humans actually perceive material appearance. Many studies have tried to understand the visual cues that are key to the perception of certain material properties such as gloss or metallicity. While most research focus on realistic images, looking at abstract and artistic representations can help improve our understanding: artists have implicitly integrated the main visual cues that need to be replicated in order to convey material appearance.
In this talk, I will present two studies on which we used artistic representations of material in order (1) to gain understanding on the key visual cues that we need to understand material properties and (2) to quantify whether our perception of material properties is similar across different styles. The studies focus on realistic paintings – low level of abstraction – and on design sketches – highly abstraction of the visual features. In both studies, we gathered material representations and the perception of their material attributes (glossiness and metallicness mainly) through online studies. We showed that simple visual features are able to predict material appearance, mainly related to the contrast and sharpness of reflections, and that those features do not differ too much from the ones that were identified for realistic images. We also designed semi-automatic features that capture those cues and allow to use a larger number of stimuli in our study. I will also discuss the limitations of more abstract representation (design design) in the representation of material appearance and how it can inform us about material perception in general.
