Morphology
|
|
----------
|
|
|
|
contains basic 2D morphology operations
|
|
|
|
inset(d=1) - creates a polygon at an offset d inside a 2D shape
|
|
outset(d=1) - creates a polygon at an offset d outside a 2D shape
|
|
fillet(r=1) - adds fillets of radius r to all concave corners of a 2D shape
|
|
rounding(r=1) - adds rounding to all convex corners of a 2D shape
|
|
shell(d,center=false) - makes a shell of width d along the edge of a 2D shape
|
|
- positive values of d places the shell on the outside
|
|
- negative values of d places the shell on the inside
|
|
- center=true and positive d places the shell centered on the edge
|
|
|
|
|
|
### Examples
|
|
|
|
With a basic sample polygon shape,
|
|
|
|
module shape() {
|
|
polygon([[0,0],[1,0],[1.5,1],[2.5,1],[2,-1],[0,-1]]);
|
|
}
|
|
|
|
and `$fn=32;`.
|
|
|
|
|
|
* `inset(d=0.3) shape();`
|
|
|
|
|
|
|
|
|
|
* `outset(d=0.3) shape();`
|
|
|
|
|
|
|
|
|
|
* `rounding(r=0.3) shape();`
|
|
|
|
|
|
|
|
|
|
* `fillet(r=0.3) shape();`
|
|
|
|
|
|
|
|
|
|
*`shell(d=0.3) shape();`
|
|
|
|
|
|
|
|
|
|
*`shell(d=-0.3) shape();`
|
|
|
|
|
|
|
|
|
|
*`shell(d=0.3,center=true) shape();`

|
Mirror
|
|
------
|
|
|
|
contains simple mirroring functions
|
|
|
|
mirror_x()
|
|
mirror_y()
|
|
mirror_z()
|
|
|
|
example:
|
|
|
|
module arrow(l=1,w=.6,t=0.15) {
|
|
mirror_y() polygon([[0,0],[l,0],[l-w/2,w/2],[l-w/2-sqrt(2)*t,w/2],[l-t/2-sqrt(2)*t,t/2],[0,t/2]]);
|
|
}
