Instancing objects instead vertices

[mori3d]

hi
I wrote the following MEL code for replacing cubes instead of vertices but it doesn't work!

What's the problem?

Hey mori3d,
here is edit of your code, hope it helps.
I've commented parts, so you can figure out what went wrong.

Take care,
Darko

Thank you Darko.
I added those points which you mentioned above but that IDE didn't support .... anyway... with the above points added, it doesn't work again!
any help?

[bjeldark]

Sure, no problem..

Just not sure what you mean by "that IDE didn't support" ?
Can you share errors that you get after execution of script ?

It's working perfectly fine (in Maya 2017), as you can see from this gif.
You sure that you've used backquotes (key above "tab" button), and not single quotes ? There is difference.

[mori3d]

I mean the IDE that I coded in it
Mine looks like this:

yes I used backquotes on top of tab key but doesn't work yet...

[mori3d]

May I ask you share your codes with me for comparison?

[bjeldark]

You could write it in notepad, it doesn't matter - this Maya's default script editor is ok.

What actually doesn't work ?
What errors do you get ?
I can not help you out, if all info you provide is: "doesn't work"..

P.S. That's the whole code, picture above - nothing more than it.

[mori3d]

Ok! Now, I've got what you mean.... Sorry...
When I run the script, all of cubes will be at the centre of coordinate; that is no cube will be in the place of each CV.
I'm using Maya 2017.

Here is the script.

[mori3d]

Can you send me your script, please?

[bjeldark]

Ok, now I got what's troubling you.
You should go with xform command anyways, and query world coordinates (funny enough, this approach of yours actually works with vertices on plane)..

Here you go:

Just to clarify xform command to you:

-q stands for query
-ws stands for world space
-t stands for translation

So, you query translations of each vert in world space (X, Y and Z), and then you move cube to that position, again with xform command.

[mori3d]

That's it!
Thank you so much
I should learn more about xform...
The only thing which is left, my script even doesn't work with vertices on plane. Why?

[mori3d]

can you solve this problem using MEL?

Modeling Generative Design in Maya

[bjeldark]

Well, actually it's strange that it worked for me - since getAttr is retrieving local values, not world space coordinates.
So, it was getting local values of verts, and if you haven't moved them at all, it returned 0, 0, 0 - so, all new cubes were positioned at that location, i.e. at world center..

P.S. I would suggest skipping Maya for this organic stuff; maybe try ZBrush..
