[Question] Where is the pivot property? #76

Open James-A-White opened 4 years ago

James-A-White commented 4 years ago

Just curious, on the SCNNode object there is a pivot property, I don't see that exposed in ARKit. I'm sure I must be missing something basic.

I'm trying to rotate text around its centerpoint and (evidently) to do that I need to access the pivot property.

Many thanks for the great package! I'm having so much fun working with AR!

Unfortunately, it's not there yet. ARKit is huge, hence I'm adding the functionality only when someone needs it. It should be easy to bridge the pivot property, hence I'll do that right after I finish with another task.

Excellent! Many thanks!

Hey @olexale if you can guide me I can take this issue 😄

Hi @Rohithgilla12 . Sure, the code will be identical to any other node's property. You may pick, for example, position as a reference. The only difference is that the pivot is a matrix, hence you'll need to use not vector3 converter, but matrix4. Feel free to ping me in case of any questions. Thanks!!

Sure, I will give it a try and ping you if I struck anywhere. I guess I need to make changes in this file https://github.com/olexale/arkit_flutter_plugin/blob/master/lib/arkit_node.dart and use one of the converter from https://github.com/olexale/arkit_flutter_plugin/blob/master/lib/utils/json_converters.dart

Awesome, can you assign the issue to me, I will start working on it.
