Move points to a '3D grid'
-
-
In case TT is away...
Inside the code making the menu use
{GridSnap**.adjust_vertices(1.cm)**}
It affects the whole model.
This example uses 1cm grid
Use another 'tolerance' if desired...
If you use()
it defaults to 0.25m anyway...
It's only some example code and could be better assembled into something working on a selection with warnings and an 'undo' ??? -
Not sure this reduced poly rock is so good ?
'Cuboidalizer' is another name idea too... that or 'Discombobulizer'
-
Here's a beta version with an inputbox and undo operation...
It seemed to only change a cubes vertices in the Z axis ??

Should apply to X,Y and Z... Seemed to work correctly in my quick test...

It's like Autotune for cad! They can make you sound good, even if you can't sing.
If you are editing digital music, and you need to make the drum beats perfect, you can move the beats to the nearest sixteenth note, or whatever. It's call "quantizing". -

TRUE !!
Restriction to discrete values (or multiples thereof,) rather than any values in the set of possibles (real numbers, in this case.)
So.. the long term:
Vertex Positional QuantizationThe short form:
Vertex to Grid -
Hi guys, I have had a play with Dan's Beta version and for me it works really well. The verticies are adjusted in X,Y and Z directions and the undo function works fine!
The only slight problem: it adjusts all the geometry in the model, rather than just the active selection. The original module just adjusted the active selection.
Any ideas?
Again thanks for the support - this script should be a realy time saver!

Well .. I did not think I changed the context of what Thomas' code did... just tried to wrap the code properly and added the menu_command() method to handle an inputbox.
I'll have a look at it.. again.
(And it's not really MY edition just because I added the inputbox.. it's still Thomas' thing.)
-
OK... added support for a selection. (Pssst! ... there was no selection support from the beginning Ross.)
This utility should probably be wrapped in Thomas' toplevel author module, and reside below his author directory in some manner.
I'll leave those choices up to him, and when he releases version 1.0.0, we'll delete these beta versions in this thread and put in a link to the release thread.

Is there an easy way to have it go through the Outliner list and open each model group and snap those corners to the grid?
What would need changed in the script so that it would snap all visible geometry to the grid, Without having to manually select and open each group? -

It would need to iterate the model's definition list, changing those that have instances.
But I'm not sure if it is really safe to change entities collections outside the current context?

That should be ok. One just need to keep in mind that the current open context apply a transformation that affect 3d points.
-
Ok.. but are ya gonna repost under
TT_GripSnap
or whatever? (I had said we'd remove the code blocks above and replace with Store links when done.) -
This wasn't something I ever planned to publish. It was just a code snipped posted for anyone to grab.
