Slides and demo code for my Tech Talk ("Shadow Mapping", 27th January 2021) in the Churchill College Computer Science Talks 2020-2021 series.
For this project, I carried out research about Shadow Mapping in real-time 3D graphics, and produced a 25min talk explaining the technical details and challenges of this method for rendering shadows. Moreover, I did a live demonstration of Shadow Mapping using a renderer I implemented (based on my OpenGL Renderer in Java project). I gave this talk to 40+ computer science students and college fellows via video conference on January 27th, 2021.

Real-time 3D graphics are a key aspect of many fields nowadays, such as modern computer games. These aim to achieve a level of realism that would not be possible without the presence of shadows caused by directional and point lights. However, due to the nature of the rendering pipeline, special techniques must be used to be able to render images with shadows.
In this talk, I will introduce the main technique used nowadays: Shadow Mapping. We will go through the idea behind Shadow Mapping and how it is implemented, discussing the possible artefacts that may occur and how to mitigate them. I will conclude with an interactive demo visualising the different parts of the process.
An extract from the talks' website:
Each week, students, fellows and veteran practitioners deliver presentations on topical, pertinent and pressing issues in Computer Science. The talks are technical in nature and consider implications and opportunities for Computer Science in the modern society. This enables everyone to explore cutting-edge aspects of Computer Science outside the confines of the University lecture syllabus which is set 18 months in advance. Topics are wide-ranging, across both theoretical and practical areas of Computer Science.
The talks are an essential aspect of personal development for our undergraduates and postgraduates, and bring the Cambridge community together. We develop the crucial skills necessary to master new technologies and apply them in the fast-paced modern world. Speakers use graphics, software demonstrations and prototype hardware to inspire the audience and provoke lively discussion and inform the community.
