In the field of three-dimensional computer graphics, rendering refers to the process of generating images of a scene from a particular viewpoint. There are many different ways to do this, from the highly interactive real-time rendering methods to the more photorealistic and computationally intensive methods. This work is concerned with Physically Based Rendering (PBR), a class of rendering algorithms capable of achieving a very high level of realism. This is achievable thanks to physically accurate modelling of the way light interacts with objects in a scene, together with the use of accurately modelled materials and physical quantities.peer-reviewe
