Computer Graphics 2.7: Aliasing and Anti aliasing Techniques

WebJul 3, 2024 · Better and sophisticated supersampling techniques are developed by graphics card companies like CSAA by NVIDIA and CFAA by AMD. Pre-filtering (Area Sampling): In … WebPre-Filtering or Area-Sampling - The areas of each pixel's overlap with the objects displayed are taken into account while calculating pixel intensities in area sampling. In this case, the computation of pixel colour is centred on the overlap of scene objects with a pixel region. Example: Let's say a line crosses two pixels. WebSamples are never taken from outside a rendered primitive, so images produced using point-sampling will be geometrically correct, but filtering quality may be low because the proportion of bits set in the pixel's coverage mask may not be equal to the proportion of the pixel that is actually covered by the fragment in question.
