title: Can we use SceneForm/SceneKit without ARCORE/ARKit for 3d model rendering
body: <p>Thank you for taking time to read this question.
  We are developing a ML Object Detection mobile app and we are planning to place object within the Bounding box when the object is detected.
  Currently we are searching for solutions which will help us place a 3d model within the bounding box. We want the 3d model to be placed on the bounding box with a transparent background to make it look 'AR'. We don't want to move to ARCore because we want to stick to our ML solution.</p>
  <p>Can you please let me know if we use SceneForm without ARCORE for 3d model rendering.</p>
  <p>PS : Right now we have used flutter for cross platform development. But we are looking to move to native development because we are not able to find any flutter widgets/libraries to render other 3d models on a transparent background</p>
