How to random scale copies on pointcloud

[Maximus]

Hello guys, i'm tryin to get the copied mesh random scaled after they got scattered into a grid pointcloud, but
i dont understand what i'm doing wrong.

At first the "Scaling" port of the create copies form polygon only accetps per point data, so i couldnt find a node except scalar to 3d vector.
The X Y Z of the scalar to 3d vector also accept only per point data, so i cant use Randomize around value wich i expected to be using :/

Any suggestion?



thanks

'Random Value' needs some ID in order to make differences. You can type Self.ID in Get Data node and plug this into ID of Random value.
However, I think that 'Randomize Around Value' should work too (probably is limited to scalar). So, something like Randomize Around Value> Multiply by Scalar. In 'Multiply by Scalar', plug some Constant 3d vector, type 1,1,1 in 3d vector as an 'starting' value.

It's probably easiest just to randomize the particles' Size. When using a point cloud, the particle Size gets used by default.

Thanks both!

@mathaeus your method would work but it doesnt accept per object data, it wants only per point datas, after i built the nodes you said it always output per object datas, so didnt pipe into the scaling node

@graham thanks! that worked pretty quick!

yeah what I said probably would work if you set this on point cloud, not this ICE tree - which is... somewhere else.

ok so here is another thing, wich is the whole reason why i started this experiment
as you might remember Mathaeus i'm referring to the other post where we spoke polygon copies!

ok now, lets say i have an Object for example a bottle, and i want those spheres to be copied and instanced into a particular zone of the bottle, it can be an extrated curve from the bottle, (wich i prefer to use to have more control on where i want to scatter copies).

My problem is exactly this, since the topology node wants a pointcloud input to scatter copies into, how do i convert the curve points into pointcloud points?

I've tried everything in my knowledge but i just cant get this to work.
I want basically to have full control of where the copies are scattered, and not with a pre-made shape like the pointcloud grid, sphere or the preset you get when you create a pointcloud.
I want to use my curve with a custom profile and i want to have this curve pipe into the topology compound, since it accepts only pointcloud, again i have to find out how to create a pointcloud that have the same exact amount of points and the same exact position of the points of my curve!

I hope i explained myself

Thanks!!

Here's how to do it.

wow that is exactly what i wanted to do!
thanks a lot!
