copied!<p>I remember reading (a long time ago) a short description of an algorithm to do so:</p> <ul> <li><p>for the general form of the line, you split the segment in two at a random point, and move this point slightly away from it's position (the variation depending on the distance of the point to the extremity). Repeat recursively/randomly. <strong>In this way, you lines are not "perfect" (straight line)</strong></p></li> <li><p>for a given segment you can "overshoot" a little bit, by extending one extremity or the other (or both). <strong>In this way, you don't have perfect joints</strong>. If i remember well, the best was to extends the original extremities, but you can do this for the sub-segment if you want to visibly split them.</p></li> <li><p>draw the lines with pattern/stamp</p></li> <li><p>there was also the (already mentioned) possibility to drawn with different starting and ending opacity (to mimic the tendency to release the pen at the end of drawing)</p></li> <li><p>You can use a different size for the stamp on the beginning and the end of the line (also to mimic the tendency to release the pen at the end of drawing). For the same effect, you can also draw the line twice, with a small variation for one of the extremity (be careful with the alpha in this case, as the line will be drawn twice)</p></li> <li><p>Last, for a given line, you can do the previous modifications several times (ie draw the line twice, with different variations) : human tend to repeat a line if they make some mistakes.</p></li> </ul> <p>Regards</p>
