The institute, led by professor Park Woo-chan of the department of computer sciences and engineering, is focusing on developing technologies for real-time path tracing, the next frontier in GPU rendering beyond conventional ray tracing. Ray tracing is a computer graphics technique that renders highly realistic images by simulating how light travels and interacts with objects in a scene. Path tracing is an advanced form of ray tracing that simulates the complete path of light as it bounces around a scene, producing images that are extremely close to real-world lighting. While path tracing enables ultrarealistic graphics that are virtually indistinguishable from reality, the severe noise generated during real-time rendering has long remained the biggest hurdle to its commercialization. To address these challenges, the institute is developing a proprietary r
