Using AI to create lifelike digital worlds

91直播 researchers are using AI to help digital worlds look and feel more lifelike. By focussing on how light behaves on materials, they鈥檙e already creating realistic images much more efficiently than with existing technique.

Artificial intelligence is transforming how we experience digital media, from the games we play to the films we watch. At The University of Manchester, Dr Zahra Montazeri, Lecturer in Graphics and Virtual Environments, is using AI to make these virtual worlds feel more real than ever. 

Her research focuses on designing realistic digital materials 鈥  

like cloth, hair, and fur 鈥 that behave naturally under changing light and movement. Traditionally, achieving this realism meant simulating every bounce of light, a process that demands huge amounts of time and computing power. Instead, Dr Montazeri鈥檚 approach uses AI to learn how light interacts with different materials, creating lifelike textures far more efficiently. The result is digital content that looks and feels real but can be generated in a fraction of the time. 

鈥淎s digital experiences become more immersive, how real things look matters more than ever,鈥 she says. 鈥淏y combining AI with advanced rendering techniques, we can make virtual worlds more convincing and engaging for everyone.鈥

Meet the researcher

Dr Zahra Montazeri is a Lecturer in Graphics and Virtual Environments at The University of Manchester. Her field of research is in physics-based computer graphics with a focus on photorealistic rendering and appearance modelling for complex materials such as cloth, hair and fur. She has worked as a research consultant for Disney Research and currently collaborates with Weta Digital. Dr Montazeri received a Star Wars movie credit for The Mandalorian and her research paper was used in the production of Avatar: The Way of Water.
