How to set zoom level(initial,min , max)??

@shikharka the initial zoom level is calculated based on the number of nodes in the system, in a cubic relationship.
For reference, this is where that logic is applied:
https://github.com/vasturiano/3d-force-graph/blob/master/src/3d-force-graph.js#L132

There is no way currently to specify zoom max/min boundaries programmatically from outside the component.

It will be a good to have feature
I found 'e.camera.position.z=150*Math.cbrt(e.forceGraph.graphData().nodes.length) ' in the js. If 150 can be passed through a variable having default value 150 and will overridden by a value passed by ForceGraph3D function, it might work

@shikharka from v1.22.0 you can now specify a custom distance using cameraPosition. F.e:

myGraph.cameraPosition({ z: 1000 });

Hello, and is ther any wat to tell the graph not to move? I mean, the first time it'is like the 3D grapgh flies away from my div...

By exposing tbControls like you exposed camera and scene I was able to set the min and max zoom and also disable rotation which I needed to display a 2D graph. Could you maybe expose this, so that my code doesn't differ from the one on repository.

Thank you,

Hi, can you please explain how you set min and max zoom.

[vasturiano]

@shaliniBITC you can access the various config of TrackballControls via the .controls() method.
So, for min/max distance:

myGraph.controls().maxDistance = 2000;
