this is already set in the EnumProperty default. If you are doing this just to trigger update_operation, just call it straight up.
- self.operation = "PRODUCT"
+ self.update_operation(context)if you really need to.

good point. I did add the default value to the enum after I had added the above code in sv_init :)

And here’s a fun application.. the node speaks fluent binary 😉
|
|
And another fun (practical) application: 3D grids. well. i’m sure there are other ways to create this ouptut... however, the real fun begins beyond 3D :) Obviously this setup can also create 4D grids (useful for the developing of the quaternions / 4D math nodes 😉 )

If there are no objections, comments, suggestions.. this node should be ready to land. |
|
Btw, currently the node is placed in the BETA section of the index.md... (though its node/doc file location is in List Mutator). If appropriate I can move it to the List Mutator in the index as well, unless it is recommended to keep it in beta for now until it is further beta tested by users. |

oops. cut and paste :)
The combinatoric operations implemented so far (based on itertools module) are:
PRODUCT
PERMUTATIONS
COMBINATIONS
The node is vectorized and works with lists of any type.
Node UI:
Product operation:
note: The example shows the product of 3 different lists (numbers, strings and vertices).
Permutations operation (with vectorization):
Combinations operation (with vectorization):
