Is there a way to scale SCNNode as per its parent SCNView's frame?

Question

I am having a 3D model loaded using a collada file on a Scenekit project using ObjC language. I would like to achieve dynamic scaling of the 3d model i.e a SCNNode just like as AutoLayout applies to any UIControl with constraints applied on them.

I want SCNNode scaled to the factor as that of its parent SCNView's scaling factor without clipping any parts of 3D model.

If it's possible how do I achieve the same?

There is no convenience to do that automatically. You'll have to place the camera according to its field of view and the object's dimensions.

See How to calculate the z-distance of a camera to view an image at 100% of its original scale in a 3D space

Maybe I missed something but I don't see why you have to manipulate a camera.

Any SCNNode has the property of .scale, why not use that?

geometryNode.scale = SCNVector3(x:xscale,y:yscale,z:zscale)

What is the equivalent in Obj C ? – toto_tata Sep 07 '17 at 16:10
