متن کاملHigh-Quality Screen-Space Ambient Occlusion using Temporal Coherence
Ambient occlusion is a cheap but effective approximation of global illumination. Recently, screen-space ambient occlusion (SSAO) methods, which sample the frame buffer as a discretization of the scene geometry, have become very popular for real-time rendering. We present temporal SSAO (TSSAO), a new algorithm which exploits temporal coherence to produce high-quality ambient occlusion in real ti...

متن کاملMulti-objective Optimization of web profile of railway wheel using Bi-directional Evolutionary Structural Optimization
In this paper, multi-objective optimization of railway wheel web profile using bidirectional evolutionary structural optimization (BESO) algorithm is investigated. Using a finite element software, static analysis of the wheel based on a standard load case, and its modal analysis for finding the fundamental natural frequency is performed. The von Mises stress and critical frequency as the proble...
متن کاملScreen-Space Ambient Occlusion by Unsharp Masking of the Depth Buffer
With the advent of the programmable graphics pipeline, it has become possible to move expensive rendering processes to the GPU for real-time computation. The demand for realistic real-time rendering in games has led to the creation of GPU shaders that approximate global illumination. Our project is an implementation of one such approximation known as screen-space ambient occlusion (SSAO).
