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. WebOne of the causes of aliasing in computer graphics is the fact that only a finite number of rays can be sampled from the scene. No matter how many rays are packed, one can always miss an object if it is small enough or far enough away. ...
