A Tool for Constructing and Visualising Bidirectional Scattering Distribution Functions

Submitted in partial fulfillment of the requirements for the degree of B.Sc. Information Technology (Software Development) (Hons.) at The University of Malta (2018).

I worked under the supervision of Dr Keith Bugeja and Dr Sandro Spina to design and build a framework and visualiser to assist with working with light scattering models in game design and animation, and an integration to utilise the framework in an open-source physically-based renderer.

Using Java and LWJGL, I built a framework and visual interface to construct arbitrary Bidirectional Reflectance Distribution Functions (BRDFs), a core term in the rendering equation, verifying the physical plausability of the BRDF implementations. Java-based Sunflow renderer was used to test the models’ image quality and signal-to-noise ratios for various renders.
