Pre filtering in computer graphics
Web20.1 Introduction. High-fidelity real-time visualization of surfaces under high-dynamic-range (HDR) image-based illumination provides an invaluable resource for various computer graphics applications. Material design, lighting design, architectural previsualization, and gaming are just a few such applications. WebPre-Filtering • Direct convolution methods are slow –A pixel pre-image can be arbitrarily large •Along silhouettes •At the horizon of a textured plane –Can require averaging over thousands of texels –Texture filtering cost grows in proportion to projected texture area • Speed-up –The texture can be prefiltered before rendering

WebAnti-Aliasing. In digital signal processing, anti-aliasing is the technique of minimizing aliasing (jagged or blocky patterns) when representing a high-resolution signal at a lower resolution. In most cases, anti-aliasing means removing data at too high a frequency to represent. When sampling is performed without removing this part of the ...
