How to curve deform a line of points - of specific uneven distances - and then instance on these points following the curve's rotation?

You can map the $x$ coordinate to the curve factor: As the OP already figured, the setup requires a slight adjustment if you don't want to "fill" the curve and instead want to maintain the ...

I want to distribute two kinds of objects on instances (grid, or points in volume) with a gradient

I would do it like this: put the two objects in a collection which you reference in Geometry Nodes through a Collection Info node. Make sure the node is set to Separate Children and Reset Children. ...

How to create Meshline according to each geometric edge vertices using GeometricNodes?

shmuel's answer is the good one because this is the explaination we needed, but if you want a line made by two vertices for each edge, you can simply duplicate the edges (shifted up so that we can see ...

Geometry Nodes: How to stop Instances from clipping through each other?

As already correctly noted in The Kalaakaar's comment, the information about the dimensions of an object is unfortunately not available to you when instantiating it. The solution would therefore be to ...
