متن کاملInteractive direct volume rendering with physically - based lighting
The field of volume visualization has undergone rapid development during the past years, both due to advances in suitable computing hardware and due to the increasing availability of large volume datasets. Recent work has focused on increasing the lighting realism in interactive raycasting by integrating a number of visually plausible but often effect-specific optimizations. These improvements ...
متن کاملSpecular Lobe-Aware Filtering and Upsampling for Interactive Indirect Illumination
ρi(ω)max(ni ·ω,0)≈ μiG(ω,ξi,λi) , where μi = Mi(ψi,ξi)μ ′ i max(ni·ξi,0) Ri . To compute this approximation, the view direction ψi, surface normal ni, reflectance Ri, and BRDF parameters (e.g. ni) are necessary. For deferred shading pipelines, ni, Ri and BRDF parameters are given by the G-buffer. The view direction ψi is computed with the camera position and the position yi which can be given b...
متن کاملFiltering Environment Illumination for Interactive Physically-Based Rendering in Mixed Reality
Physically correct rendering of environment illumination has been a long-standing challenge in interactive graphics, since Monte-Carlo ray-tracing requires thousands of rays per pixel. We propose accurate filtering of a noisy Monte-Carlo image using Fourier analysis. Our novel analysis extends previous works by showing that the shape of illumination spectra is not always a line or wedge, as in ...
متن کاملInteractive Physically-based Sound Simulation
Nikunj Raghuvanshi: Interactive Physically-based Sound Simulation. (Under the direction of Ming C. Lin.) The realization of interactive, immersive virtual worlds requires the ability to present a realistic audio experience that convincingly compliments their visual rendering. Physical simulation is a natural way to achieve such realism, enabling deeply immersive virtual worlds. However, physica...
