![]() Our method can deliver 4x speed up for scenes that are computationally bound by ray tracing costs. We also present a new rotationally-invariant filter that easily handles samples spread over a large angular domain. We give a frequency analysis of shadow light fields using distant illumination with a general BRDF and normal mapping, allowing us to share ray information even among complex receivers. However, many nearby rays sample similar areas, and the final occlusion result is often low frequency. This is part of the Unigine line of hardware/software performance benchmarks that are designed to push GPUs to the limits of new hardware. Moreover, each ray can be expensive in scenes with moderate to high geometric complexity. However, ray-traced solutions for hemispherical occlusion require many rays per shading point (typically 256-1024) due to the full hemispherical. Working together, these effects provide incredibly realistic lighting and shadow-play simulation for real-time interactive rendering.Īmbient occlusion and directional (spherical harmonic) occlusion have become a staple of production rendering because they capture many visually important qualities of global illumination while being reusable across multiple artistic lighting iterations. The use of bent normals helps to reduce the noise and smooth borders of shadows, while global illumination recreates light reflections from surfaces. This ray-tracing technique provides ambient occlusion with more realistic shadows between the objects. Superposition continues the line of GPU benchmarks by UNIGINE used by tens of millions people around the. They produce only a rough imitation, while SSRTGI provides real 180-degree ray tracing for each pixel in the scene with a fixed number of steps per ray to define occlusions. UNIGINE presents the new Superposition Benchmark. Ordinary screen-space effects, such as SSAO and SSGI, do not treat objects as obstacles for light rays, so they are not able to provide realistic lighting simulation. The UNIGINE team developed a brand-new lighting effect that makes an interactive real-time-rendered environment look photorealistic: screen-space ray tracing global illumination (SSRTGI), a technology that brings rendered ray tracing closer to real physics. Its a bit of a weird time being a Vega 64 owner, 2 cards released and no worth-wile. Superposition Benchmark is a next-generation GPU benchmark that continues the line of UNIGINE benchmarks, famous for outstanding and innovative 3D graphics. It might not be as famous as the Heaven and Valley benchmarks, but if you've never treated your eyes to the spectacle of Unigine Superposition benchmark and its glorious rendition of a professors study then you're really missing out. ![]()
