Let’s break down what RTGI is, why it’s so expensive to run, and why it matters.
Consider the difference in a single frame: a ceramic coffee mug inside a dimly lit cabin. With rasterization, the handle is dark, a void. With RTGI, the light from the window bounces off the pinewood table (absorbing its amber tone), hits the underside of the mug's handle, and wraps around the ceramic in a warm, soft caress. The shadow is not a black cutout; it is a penumbra, soft at the edges, colored by the bounce light from the ceiling. You don't notice RTGI. That's the point. You notice its absence—a deadness, a flatness—like a room with no echoes. Let’s break down what RTGI is, why it’s
Initial versions often featured "noisy" lighting and required heavy denoising filters, sometimes resulting in a "shimmery" look in shadows. With RTGI, the light from the window bounces
Objects like neon signs or glowing computer screens act as actual light sources that illuminate their surroundings in real-time. The Evolution of RTGI Technology That's the point
