Think Like a Computer Science Professor

Observe the thought process of a computer science professor as he codes a project from scratch in this 13-hour video. Follow along as Radu Mariescu-Istodor, a PhD in computer science, demonstrates real-time problem-solving and decision-making while building an interactive avatar system. Learn about canvas setup, procedural drawing, image processing, particle systems, linear algebra, and real-time face tracking. Watch as Radu tackles challenges like head rotation, dynamic hair simulation, and facial feature recognition without referencing external resources. Gain insights into code refactoring, debugging techniques, and the iterative nature of software development. This comprehensive coding session covers everything from initial planning to final testing, providing a unique opportunity to understand the mindset and approach of an experienced computer scientist.
