: It does make a difference in the resulting tree: the adjacency strategy makes particles have a larger "cross section" for collisions, and it will probably cause a difference in the appearance of the tree. But an even stronger influence is where the particles are added to the field. —[[User:Kevin Reid|Kevin Reid]] 22:25, 19 July 2010 (UTC)
:: Given a specific sequence of numbers to have fed out of the PRNG call (or using the same seed each time), it would be interesting to compare outputs from the two approaches. --[[User:Short Circuit|Michael Mol]] 15:53, 20 July 2010 (UTC)
:: The tree shape is very sensitive to how collision is defined. The way each new particle attaching to the tree affects who itself can be used as an anchor later, sort of like a fractal. From tests I did, small changes to some details (how far away the stuck particles are from each other, whether Brownian motion is slightly biased, at what distance are two particles considered colliding, etc) make the trees look completely different. Some code examples produced images that don't look like trees at all, I guess this is why. --[[User:Ledrug|Ledrug]] 02:55, 11 June 2011 (UTC)
