 One can use the routine tremble in order to deform a specific path. (Compiled with Asymptote version 1.87svn-r4652)
```
import trembling;
size(8cm);

path cle=unitcircle;

/* View the definition of path tremble(path,real,real,real,real) */
path tcle=tremble(cle,frequency=0.25,random=1);
draw(tcle);

path tri=(-1,-0.5)--(1,-0.5)--(0,0.75)--cycle;
path ttri=tremble(tri,frequency=0.5,random=1.5);
draw(ttri);

shipout(bbox(3mm,invisible));

 Using the routine startTrembling, all drawn paths are distorted. (Compiled with Asymptote version 1.87svn-r4652)

/* View the definition of void startTrembling(real,real,real,real,bool */
startTrembling();

draw(unitcircle);

## Asymptote using trembling.asy – fig0030

Category: Asymptote,Examples 2D,trembling.asyPh. Ivaldi @ 4 h 24 min

 When trembling is enabled with the routine startTrembling, all (most ?) doted points become "magnetic" automatically. So, if a path passes through a magnetized point with an numerous precision defined by magneticRadius (unit is bp in postscript coordinates), the resulting distorted path will also pass through the point.

 One can disabled this feature setting the parameter magnetizePoints to false. (Compiled with Asymptote version 1.87svn-r4652)

 One can magnetize non dotted points with the routines void magnetize(...triangle[]) and void magnetize(...pair[]). (Compiled with Asymptote version 1.87svn-r4652)

import trembling;
startTrembling();

size(8cm);

triangle T=triangleabc(6,7,8);
