Sure but inside this one you can see how select your colors...
so maybe a mix is possible...

Hi Ed,
It should be possible to select a random style from a more or less sequential set of styleIndex values.
In the ModulationTest2 script that Michael helped me with several years ago, the function AssignColors was used. It would have to be randomized over the desired range of style indexes. Generate a random number between 0 and 6, and add it to the beginning of your selected range of styles....
Apply and repeat...

Hi Ed,

re:
> But is there a way to specify just a subset of colors from the Styles?

So the code that generates the style index is this part here (it's in 2 places in the script one for where it sets up edges and another faces):

styleIndex = Math.floor(Math.random() * styles.length);

If you wanted it to choose only from the first 10 styles, you could do it like this instead:

styleIndex = Math.floor(Math.random() * 10);

If you wanted it to choose from the last 10 styles, you could do it like this:

styleIndex = styles.length - 1 - Math.floor(Math.random() * 10);

Thanks Michael!

Tested here using first 6 default colors in Styles list.

script: /* Assign random styles to faces and edges */ var styles = moi.geometryDatabase.getObjectStyles(); var breps = moi.geometryDatabase.getObjects().getBReps(); for ( var i = 0; i < breps.length; ++i )
{ var brep = breps.item(i); var edges = brep.getEdges(); for ( var j = 0; j < edges.length; ++j ) { edges.item(j).styleIndex = Math.floor(Math.random() * 6); } var faces = brep.getFaces();
for ( var j = 0; j < faces.length; ++j ) { faces.item(j).styleIndex = Math.floor(Math.random() * 6); } }
