ATTENTION: We're pleased to announce that EI 2021 will be fully online! We recognize that one of the most important features of attending EI is interacting with colleagues from Industry and Academia. We are committed to making community connection a priority and to providing ample opportunities to meet and discuss personally with others. We see the move to an online platform as an opportunity for greater numbers of people to join from around the world. Join us on this exciting adventure . . . submit your work today!

Conference Overview

The Material Appearance Conference is entering its seventh year. For many manufactured and natural products, appearance is a signature of quality and a criterion of choice for end-customers. Material appearance is therefore crucial to evaluate, physically and/or perceptually.

Appearance is also increasingly important to 3D printing and new surface coating/texturing technologies, which aim at either reproducing the visual aspect of typical objects, or designing innovative ones.

From the definition of appearance attributes, such as color, gloss, or translucency, to the practical ways these attributes can be evaluated in a specific applicative context, e.g. instruments able to quantify the glossiness of human skin before and after application of a cosmetic product, the Material Appearance conference aims at gathering a broad variety of knowledge, and rendering the current pioneering research in both academic and industrial laboratories for the promotion of efficient appearance evaluation tools.

The inter-disciplinary nature of the conference is rendered by a variety of classical and interactive sessions:


Invited keynote presentations by well known professionals from industry and academia


Appearance measurement methods, Optical models, Visual rendering and computer graphics, 3D printing, Fashion & Beauty, etc.

Thematic discussions

e.g., appearance and quality, appearance tools for design, measurement techniques and performances, etc.

Rarely Asked Questions Forum

Come to expose your specific question on material appearance, and/or come to provide your expertise

2021 Conference Topics

Measuring and predicting appearance

  • Optical measurement techniques (spectrophotometry, BRDF, PSF, 3D imaging, OCT, polarized imaging, non-invasive measurements...)
  • Light-matter interaction models (light scattering, translucent materials, flux transfer models, wave optics, inverse approaches)
  • Deep learning approaches

Perceptual characterization and display (with COLOR)

  • Perceptual attribute assessment and representation (colorimetry, gloss assessment, etc.)
  • Sensorial metrology
  • Hyperspectral imaging
  • HDR / spectral display for material appearance

Appearance reproduction and design

  • Technologies: 3D printing, special effect coatings, surface texturation
  • Soft proofing methods
  • Reproduction quality assessment
  • Materials for fabrication

Simulation and computer graphics

  • Virtual proofing for design
  • Image synthesis
  • Virtual, augmented, and mixed reality


  • Art, textile, cosmetics, automotive, object design, 3D printing, manufacturing, lighting, e-commerce, security

2021 Special Session

For Material Appearance 2021, submissions are particularly encouraged for the planned cultural heritage session.

Material Appearance in Cultural Heritage

Session Organizing Chair:
Sony George, Norwegian University of Science and Technology (Norway)

The MAAP Material Appearance in Cultural Heritage special session is dedicated to publishing and presenting research and development activities and results in the Cultural Heritage domain with a primary focus on, but not limited to, Measurement of material appearance, Multimodal imaging, Monitoring and Tracking Change in Appearance, Assessment, Visual appearance rendering and Visualization of cultural heritage objects and materials.
