Thank you for your inspiration. I was able to answer my own questions.

The trick was to start at the project view level

SCView *sceneView = (SCNView *) self.view

the rest was simple. I will create a blog to share what I was playing with. This is great stuff.

I got a little further and managed to add another component

1. creating a pointer

NSURL *wheelTwo = [[NSBundle mainBundle] URLForResource:@”base30w” withExtension:@”dae”];
SCNScene *wheelScene = [SCNScene sceneWithURL:wheelTwo options:options error:&error];

2. adding it to the scene.rootNode

[scene.rootNode addChildNode: wheelScene.rootNode ];

SCNNode *theWheel = [scene.rootNode childNodeWithName: @"base30w" recursively:YES];

3. attempting a transform however errors

theWheel.transform = CATransform3DMakeTranslation(100, 100, 100);

> the error
[SCNKit ERROR] removing the root node of a scene from its scene is not allowed
I wonder if you may have any thoughts on how to manipulate the additional object

The error occurs only when I implement > theWheel.transform plus parameter
thanks for any thoughts

Thanks for your answer hope its ok to ask again with more details. I want to add several DAE files into the scene and want to assign node names to them thus far I was only assign the example object as rootNode.
// Load a scene
NSURL *url = [[NSBundle mainBundle] URLForResource:@”firstWheel” withExtension:@”dae”];
[self.view loadSceneAtURL:url];

This is where I am a little lost, I can use this object and do some simple animation with it ( my code example below ). But I only managed to do this as scene.rootNode. I want however load at least to more DAE-files to the same scene. Hope you may have an answer to get my over the wall. Thank you so much in advance

SCNScene *scene = [SCNScene sceneWithURL:url options:options error:&error];

animation.values = [NSArray arrayWithObjects:
[NSValue valueWithCATransform3D:CATransform3DRotate(scene.rootNode.transform, 0 * M_PI / 2, 0.0f, 0.00001f, 0.000f)], nil];

Thank you for your comment Helmut. I’m not sure if you’re asking about my code or your own. In my own code I add each separate object on my view like this,
Dim aPyramid As New SCNPyramidTJC(......) // do other stuff here Dim temp As New SCNNodeTJC() temp.Pointer = mScene.RootNode temp.AddChildNode mPyramidNode.Pointer
Does that help you? The projects I’ve released are just proof of concept type projects. If Real ever releases their new IDE where I can encrypt projects I would post the project, but for now, I’m not going to.

Nice work, I try to use the sample code my self but did not get this far.

Got some problems to load more than one Object to the scene. How did you
create child Node from the object ( your code example below) after loadSceneAtURL

Thanks for sharing your work and your thoughts.

Me.InitializeView
Me.AllowsCameraControl = True
Me.JitteringEnabled = True
Me.Playing = True
Me.AutoEnablesDefaultLighting = True
Me.BackgroundColor = &c00000000
//
Dim aNSBundle As NSBundleTJC
aNSBundle = New NSBundleTJC(NSBundleTJC.MainBundle)
Dim bundlePtr As Ptr
bundlePtr = aNSBundle.URLForResource(“scene”, “dae”)
Dim aNSURL As New NSURLTJC(bundlePtr)
//
Me.LoadSceneAtURL aNSURL.Pointer

Comment on OpenGL Planets by bigdaddytom

Yes. It’s very common to use OpenGL in this manner. There is quite a lot of work to get to this stage however. OpenGL is just a renderer, you’d have to feed it all of the model data and write “picking” code for the mouse to rotate the molecule. Google it.

Hi, All your works a re very interesting. I’m curios and I would to know if there is any possibility with open gl to show molecular particles in a 2D and 3D view, maybe with some mouse interaction by the canvas container.
All the best,
Massimiliano.
