have one geo vertices match another geo vertices???

[stkeg]

i have some geometries that will deform. i want another set of geometries to match the vertices.

for example, i have a set of boxes that are merged to form another box (like a rubiks cube, so 27 boxes).

i want to have another set of 27 boxes match the deformed boxes. for example, the copybox1 matches deformedbox1, etc.

if i weren't modifying the vertices directly and deforming, i could have used expressions to match up the translate, rotate, pivot, etc attributes

anyone have any thoughts?

it really depends on the purpose of it. Different methods:

1. You could create a procedural animation that follows the reference. By expressions in a transformSOP

2. Create a foreachSOP, inside you could make a vopsop. Input one the cubes to deform and input 2 the reference. Copy the attributes from the reference to the cubes u want to deform. As long as the point-numbers from the input1 and input 2 are equal this shoudl work fine

3. Animate points and add a copySOP to compy the cubes you want to be animated

there are probably a lot of different ways to do this. I don't have time to put up an example file but someone else might have

Good luck!

Thinking about a lattice, hope that's what you need.

From your description you have the same amount of points in both the deformed geo and the still. than the most accurate way of solving it is with a VOPSOP.

Otherwise the lattice deformer as Remi suggested or a cloth deformer should do the trick.

Here is an example using the VOPSOP
