While tutorials exist, they largely focus on reproducing a specific style of stippled art work (e.g., Hedcut). Such techniques tend to be inappropriate to TSP art as they lack control over the number of stipples used. And, too many stipples leads to artwork which is too detailed for pen tips. Existing software which affords control over the number of stipples tends to be "research grade". That is, the software's primary design goal was not that of ease of use, clarity, or robustness. With that in mind, OS X and, maybe, Windows users as well, have the option of trying out Adrian Secord's weighted Voronoi stippler [1]. |

# After you open an image file, it may take a while before any stippled image appears. It sometimes helps to nudge things along by selecting "Relax Points" or "Jitter" under the "Points" menu item. | # After you open an image file, it may take a while before any stippled image appears.

# The program will run for quite some time while seeming to not be doing anything. It's actually trying to refine the picture it has drawn. You can go ahead and tell it to save its work while it is working on its refinements. | # The program will run for quite some time while seeming to not be doing anything.

# When you have a stippling you like, use the "Save Points" item under the "File" menu. This will write a file containing (x,y) coordinates of each point and their radii. The tspart.py script can read these files as input files. No special options need be set when running tspart.py: it automatically detects the file format. | # When you have a stippling you like, use the "Save Points" item under the "File" menu.

[2] Adrian Secord himself points out that the software is "research code". So remember that Secord's focus was not on producing a polished product but rather in accomplishing his own research goals. The author of this wiki article has rebuilt the software on OS X 10.6 and found the issue to persist. The binary version of the program available from Adrian Secord was built with OS X 10.5 but it does run on OS X 10.6. | [2] Adrian Secord himself points out that the software is "research code".
