Nvidia gives fake Harrison Ford better hair using spheres

Nvidia has introduced a new feature called RTX Hair, which aims to improve the rendering of hair in video games. The first game to benefit from this technology is Indiana Jones and the Great Circle, where it will be used to enhance the virtual hair of actor Harrison Ford. Instead of using traditional triangles, RTX Hair employs spheres to model the hair, leading to more realistic lighting, shadows, and a fuller appearance. This new approach leverages the hardware capabilities of Nvidia's RTX 50-series GPUs, including hardware acceleration for ray tracing and support for the linear swept sphere (LSS) primitive. According to Nvidia, the RTX Hair improvements are a significant step towards rendering high-quality digital humans in real-time, making the hair and overall character appearance more lifelike. The feature will be available as an update to the real-time path tracing mode in the Indiana Jones game, providing players with a more visually stunning experience.
