This is page is a place holder until I get time to write up some comments with regard to sampling patterns. This was started by a discussion on the (sadly now defunct) Dimension3D forum and then reappeared in Beyond3D's boards.

To get a good selection of line angles and frequencies, a synthetic scene consisting of concentric rings was used. A set of images was then 'rendered' using a variety of sampling patterns including regular grid super-sampling, rotated regular grid, and jittered regular grid sampling.

Aliasing effects (jaggies, moire patterns etc) are clearly visible, but decrease with increasing sample rates. With a bit of luck, I'll get around to implementing Minimum Distance Poisson Disc sampling patterns, which should give better results.

Note: The image really needs to be viewed with a 24/32bit display or else the dithering typically performed with 16bit displays will tend to ruin the effect. I think that the gamma of the display was assumed to be about 2.2
