I'll assume you mean aliasing from undersampling (and not only edge 
aliasing caused by 3D rendering).

Just decimate an image, instant aliasing. For the reference to compare 
the output of your filter against you use "good" downsampling on the 
original image, for instance by using a small radius gaussian blur 
before the decimation.
