Overview: | This lecture will present a novel technique called Adaptive Virtual Texture (AVT) rendering which is used in Far Cry 4. It will describe how we used the technique to render terrain along with a massive amount of decals very efficiently on both CPU and GPU. Traditional virtual texture rendering techniques like MegaTexture and procedural virtual texturing can suffer from low-texel resolution when applied to a large open world. Adaptive virtual texturing overcomes this problem. In Far Cry 4 it is used in a 10KM*10KM world, and achieves 10 texels/cm resolution, which is 20 times higher than traditional virtual texturing techniques. |
