how to pass a module to a module

module all(m) {
m();
mirror([1, 0, 0])
m();
mirror([0, 1, 0]) {
m();
mirror([1, 0, 0])
m();
}
}

I am finding strange this does not work. What would be the best
solution for the above problem?

Works fine for me.

all();
module all(m) {
m();
mirror([1, 0, 0])
m();
mirror([0, 1, 0]) {
m();
mirror([1, 0, 0])
m();
}
}

module m() {
cube(10);
}

Re: how to pass a module to a module

I want to pass different modules like:
module m() {
cube(10);
}

module n() {
...
}

all(m);
all(n);

Re: how to pass a module to a module

Ahhh, modules aren't objects that can be passed. You would use children() :

module all() {
children();
mirror([1, 0, 0])
children();
mirror([0, 1, 0]) {
children();
mirror([1, 0, 0])
children();
}
}

module m() {
cube(10);
}

module n() {
cube(20);
}

all() m();

all() n();

Re: how to pass a module to a module

essentially there are userspace objects that can be passed as parameters, and rendered objects, like modules, and they live in different spaces

Re: how to pass a module to a module

Thanks for pointing out the use of children(), this makes a lot more possible.

This is still a limitation compared to multiple parameters.. but I
guess openscad doesn't allow mixing passed parameters with modules.

Re: how to pass a module to a module

Modules aren't passable at all, they are in a different space

Re: how to pass a module to a module

In reply to this post by seandepagnier

You can pass parameters to children via $ variables. A bit of hack but it works.

module ten() {

let($p = 10) children();

}

ten() cube($p);

Re: how to pass a module to a module

In reply to this post by nophead

Not sure what your question was, but you can pass multiple modules as children.

module twokids() {

difference() {

children(0);

children(1);

}

twokids() {

cube();

sphere();

}

Re: how to pass a module to a module

Yes, it is. But I do find it necessary sometimes. Even worse is use $p in the child module without it being a parameter!

This is still a limitation compared to multiple parameters.. but I
guess openscad doesn't allow mixing passed parameters with modules.

You may use parameters in all() provided they are not modules:

module all(v=[0,0,0]) {
translate(v)
children();
mirror([1, 0, 0])
translate(v)
children();
mirror([0, 1, 0]) {
translate(v)
children();
mirror([1, 0, 0])
translate(v)
children();
}
}
module m() {
sphere(10);
}
module n() {
cube(10);
}

all([20,20,20]) m();
all([10,10,-10]) n();

Yes but useful when we have a big list that is constant throughout a recursive process.

I have learned a lot.. The $ variables hack is interesting, but I
hope not to use it.
