    • Assessment of OLED Head Mounted Display for Vision Research with Virtual Reality 

      Toscani, Matteo; Gil, Raquel; Guarnera, Dar'ya; Guarnera, Giuseppe Claudio; Kalouaz, Assim; Gegenfurtner, Karl (Chapter, 2019)
      Vision researchers often rely on visual display technology to present observers with controlled stimuli, usually by means of a calibrated computer screen. Virtual Reality (VR) may allow a similar level of control, together ...

    • Colour Calibration of a Head Mounted Display for Colour Vision Research using Virtual Reality 

      Rodriguez, Raquel Gil; Bayer, Florian; Toscani, Matteo; Guarnera, Dar'ya; Guarnera, Giuseppe Claudio; Gegenfurtner, Karl (Peer reviewed; Journal article, 2021)
      Virtual reality (VR) technology offers visionresearchers the opportunity to conduct immersive stud-ies in simulated real-world scenes. However, an accur-ate colour calibration of the VR head mounted display(HMD), both in ...

    • On the Acquisition and Reproduction of Material Appearance 

      Sole, Aditya Suneel; Gigilashvili, Davit; Midtfjord, Helene B.; Guarnera, Dar'ya; Guarnera, Giuseppe Claudio; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve (Chapter, 2019)
      Currently, new technologies (e.g. 2.5D and 3D printing processes) progress at a fast pace in their capacity to (re)produce an ever-broader range of visual aspects. At the same time, a huge research effort is needed to ...

    • Perceptually validated analytical BRDFs parameters remapping 

      Guarnera, Dar'ya; Guarnera, Giuseppe Claudio; Toscani, Matteo; Glencross, Mashhuda; Li, Baihua; Hardeberg, Jon Yngve; Gegenfurtner, Karl (Chapter, 2018)
      The need to manually match the appearance of a material in two or more different rendering tools is common in digital 3D product design, due to the wide range of tools and material models commonly used, and a lack of ...

    • Perceptually Validated Cross-Renderer Analytical BRDF Parameter Remapping 

      Guarnera, Dar'ya; Guarnera, Giuseppe Claudio; Toscani, Matteo; Glencross, Mashhuda; Li, Baihua; Hardeberg, Jon Yngve; Gegenfurtner, Karl (Journal article; Peer reviewed, 2018)
      Material appearance of rendered objects depends on the underlying BRDF implementation used by rendering software packages. A lack of standards to exchange material parameters and data (between tools) means that artists in ...

    • Three perceptual dimensions for specular and diffuse reflection 

      Toscani, Matteo; Guarnera, Dar'ya; Guarnera, Giuseppe Claudio; Hardeberg, Jon Yngve; Gegenfurtner, Karl (Peer reviewed; Journal article, 2020)
      Previous research investigated the perceptual dimensionality of achromatic reflection of opaque surfaces, by using either simple analytic models of reflection or measured reflection properties of a limited sample of ...

    • Towards a Consistent, Tool Independent Virtual Material Appearance 

      Guarnera, Dar'ya; Guarnera, Giuseppe Claudio; Cornelia, Denk; Mashhuda, Glencross (Journal article; Peer reviewed, 2017)
      Current materials appearance is mainly tool dependent and requires time, labour and computational cost to deliver consistent visual result. Within the industry, the development of a project is often based on a virtual ...

    • Virtual Material Acquisition and Representation for Computer Graphics 

      Guarnera, Dar'ya; Guarnera, Giuseppe Claudio (Book, 2018)
      This book provides beginners in computer graphics and related fields a guide to the concepts, models, and technologies for realistic rendering of material appearance. It provides a complete and thorough overview of reflectance ...
