• Acquiring Spatially Varying Appearance of Printed Holographic Surfaces - SIGGRAPH Asia 2018

    We present two novel and complimentary approaches to measure diffraction effects in commonly found planar spatially varying holographic surfaces. Such holographic surfaces are usually manufactured with one dimensional diffraction gratings that are varying in periodicity and orientation over an entire sample in order to produce a wide range of diffraction effects such as gradients and kinematic (rotational) effects. Our proposed methods estimate these two parameters and allow an accurate reproduction of these effects in real-time.

  • Practical acquisition and rendering of diffraction effects in surface reflectance

    I have worked on the measurement and real-time rendering of diffraction effects during the first two years of my PhD. I am happy to say that the paper has been accepted at ACM Transactions On Graphics and that I will present it at SIGGRAPH 2017 in Los Angeles, California. The code for this project is available on my Github.

  • Computer Graphics Shader Lab Framework

    ShaderLab Framework is a framework that Dr Bernhard Kainz and I implemented. It is a teaching tool that is used for the lab sessions of the Graphics course (CO317) at Imperial College London. ShaderLab Framework provides an IDE-like environment that helps students to understand the basics of computer graphics and GLSL programming. It is open-source and available on my github.

  • Image-Based Relighting Framework

    This software was implemented as part of my MSc thesis on image-based relighting at Imperial College London. It provides a user interface to render objects in arbitrary environments using data captured with a light stage, a free-form light stage or in a regular room. It is open source and available under the LGPL license on my github.
