LOGBOOK:
- No classes this year. Instructor in sabbatical.
Description
- The course addresses advanced techniques for image synthesis, both in sound theoretical and practical terms, with a focus on algorithms for offline and real-time 3D graphics.
Objectives
-
In the end of this course you supposedly will be able to master the following topics:
- physical light transport, and how to simulate this behavior in a computer program;
- modern ray tracing based rendering algorithms;
- high level optimizations of the ray tracing algorithm;
- Monte Carlo integration and variance reduction;
- GPGPU-specific optimizations of ray tracing algorithms. Also, you will be able to:
- implement a Whitted-style ray tracer and path tracer;
- implement a acceleration structure construction and traversal.
Prerequisites
- Basic knowledge in linear algebra, calculus and probability theory.
- Basic course in computer graphics at the BSc level is strongly recommended.
- Good programming skills in C++.
- Highly recommended: some experience with graphics programming (e.g. OpenGL / DirectX).
