Occlusion-Point Reuse for Ray-Traced Ambient Occlusion and Shadow
Haojie Jin, Fujia Su, Zehui Lin +9
Ambient occlusion (AO) and soft shadows are critical visibility cues for spatial perception in real-time rendering. Hardware ray tracing provides a direct way to evaluate these eff…
Hypothesis Testing for Progressive Kernel Estimation and VCM Framework
Zehui Lin, Chenxiao Hu, Jinzhu Jia +1
Identifying an appropriate radius for unbiased kernel estimation is crucial for the efficiency of radiance estimation. However, determining both the radius and unbiasedness still f…
Proxy Tracing: Unbiased Reciprocal Estimation for Optimized Sampling in BDPT
Fujia Su, Bingxuan Li, Qingyang Yin +2
Robust light transport algorithms, particularly bidirectional path tracing (BDPT), face significant challenges when dealing with specular or highly glossy involved paths. BDPT cons…
Visual Acuity Consistent Foveated Rendering towards Retinal Resolution
Zhi Zhang, Meng Gai, Sheng Li
Prior foveated rendering methods often suffer from a limitation where the shading load escalates with increasing display resolution, leading to decreased efficiency, particularly w…
