Recent Advances in Realistic Cloth Rendering

Fabrics play a significant role in our daily lives, making their digital modeling crucial for applications in online retail, the textile industry, and entertainment, such as games and movies. Despite its importance, there have been significant advances in fabric rendering techniques over the past decade to highlight the state-of-the-art advancements. Rendering fabrics is a complex task due to their intricate microgeometry and anisotropic appearance. Conventional approaches either model fabrics as 2D sheets, which are efficient but lack high fidelity in close-ups, or model them at the fiber level, trading high fidelity with significant computational costs. Recent models propose aggregation-based techniques that combine the strengths of both approaches.
