This page is the home of the Advanced Rendering Research Group at AMD, working on research surrounding graphics and rendering. We look at current and future problems relating to CPU and GPU architectures.
Research topics we study include:
- Real-time rendering algorithms.
- Global illumination using ray tracing.
- Application of Machine Learning to graphics.Â
Some derivatives from our research activities are turned into some libraries and SDKs.
Our team members comprise a wide variety of people with different backgrounds, and we work together to find solutions to problems. The team is distributed all over the world in Europe, Asia, Australia, and North America.
Publications
During the problem-solving phase, we sometimes invent new technologies. We publish this research through academic channels so it can be used by others.
Here are some of our recent research papers:
