• 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 ...
    • 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 ...
