As discussed on Meta Stack Exchange there are problems with link only answers. This Meta Computer Graphics post suggests our particular community would prefer not to have link only answers. However, having established that they are not good, there are a number of different ways of responding to them. Today we have had another example of a link only answer that the poster is reluctant to change:
See the paper Computer Modelling of Fallen Snow published in SIGGRAPH 2000.
See also what seems to be its project page.
An older paper is Simulating Dust Accumulation.
What is the best way to respond to answers like these?
