An arbitrary-dimensional diffusion-limited aggregation simulator.
v1.7 2018-12-09 2D and 3D density output supported, more command-line options supported
v1.6 2015-03-21 Enabling multiple types of bulk velocity
v1.5 2015-01-01 Smooth junctions each step
v1.4 2014-03-05 Multiple methods for segment rejection
v1.3 2008-10-18 Support file-input options on command-line
v1.2 2008-03-30 Support for "irradiation planes" and other enhancements to allow Lichtenberg figures
v1.1 2006-04-06 Chiral growth
v1.0 2005-09-14 Windows and Linux executables included
v0.9 2005-09-02 includes timer, line-at-a-time statistics file, constantly- overwritten pnd output file, random seed much faster due to elimination of slow and unnecessary routine
v0.8 2005-02-26 fixed bulk motion algorithm; now uses numeric root-finder to determine actual dt for diffusing particles added experimental rotex growth using source/sink/vortex influences
v0.7 2005-02-24 added libpng support, removed GIF support and related system calls added bit depth parameter to output file merged image_size and density pixel sizes---all output images use image_size now fixed bounds on sim-> construction variables fixed moving_particle problem in replace_all_particles() allowed automatic resizing of tree to accommodate all particles
v0.6 2004-08-31 upgraded dla3d to dla-nd other minor improvements
v0.5 2004-08-26 added grip, reorganized parameters, added obj output
v0.4 2004-02-27 corrected directionality, added bias, added stickiness
v0.3 2004-01-20 added directionality, reorganized
v0.2 2003-12-04 new output, correct aggregation
v0.1 2003-12-04 improved order over O(N^2)
v0.0 2003-12-03 copied part3d source, begin work
