Re: [OpenSCAD] [Minkowsky Text]

Hi,
I'm new on this forum and I say hello to everyone
I write here because I'm trying to use openscad to make customizable
things.
I would like to smooth the corners of a 3D text and I find that Minkowsky
works for it.
The problem is that the render during more or less 10 minutes and it's
very slow. What can I do to make more faster?
I leave here my code, thank you so much in advance.
carattere = "Futura Std";
testo = "LaceTag";
module testo()
{
linear_extrude(height=7, convexity=10)
text(testo, size=16, font=carattere,
spacing=1, direction="ltr",$fn=60);
}
minkowski(){
testo();
sphere(1, $fn=10);
}
Welcome.
You can get the rounded look on the perimeter by using offset.
linear_extrude(height=7, convexity=10)
offset(r=0.75)
text(testo, size=16, font=carattere,
spacing=1, direction="ltr",$fn=60);
You could stack a few thin layers on top, using a progressively smaller
offset.

Thank you MichaelAtOz!!
I've try and it works.
BUT, to make the shape of a sphere i try this but i doesn't work.
What's wrong? Thank you.
carattere = "Futura";
testo = "Hello World";
difference() {
union() {
for(t=[0:30:180])
{
for(i=[0:1:6])
{
translate([0,0,i])
linear_extrude(height=1, convexity=10)
{
offset(r=sin(t*10),$fn=100)
{
text(testo, size=16, font=carattere,
spacing=1, direction="ltr");}
}
}
}
}
}

I wasn't sure what you were doing with the i loop, so I just bumbled my way
to my solution.
That was an adventure...
I can't recall whether Customizer used preview or render.
This is fast on preview, but renders slowly.
It could probably be finessed, but it get the job done.
(you may want to fiddle with the spacing= & factor=)
carattere = "Futura";
testo = "Hello World";
// testo = "o";
debug=0; // set to 1 it spaces layers & numbers them
module textMsg()
text(testo, size=16, font=carattere,
spacing=1.1, direction="ltr");
module offsetSteps(high=2, slices=3,offSet=1) {
// offSet -/+, +n small->large, -n large->small
stepAngle=90/slices;
stepHigh=high/slices;
echo(slices=slices,stepHigh);
loop=([0:1:slices-1]);
for(line=loop) {
lsa=linestepAngle;
translate([0,0,linestepHigh*(debug ? 2 : 1)]) {
linear_extrude(height=stepHigh+0.05, convexity=10) {
if (debug)
translate([line*10,30,0])
text(str(line),size=6);
rad=(offSet>0 ? sin(lsa) : cos(lsa));
echo(line=line,lsa=lsa,rad=rad,sin(lsa),cos(lsa));
offset(r=abs(offSet)*rad,$fn=64) {
children();
}
}
}
}
}
factor=1.2;
// bottom round
translate([0,0,0])
offsetSteps(offSet=factor)
textMsg();
// middle just offset perimiter
translate([0,0,1.99]) {
color("blue")
linear_extrude(height=5.01, convexity=10)
offset(r=factor,$fn=64)
textMsg();
// top round
translate([0,0,4.99])
offsetSteps(offSet=-factor)
textMsg();
}
