I have created a project and tested on
- iPad real Device (iOS 9.3.5)
- iPad Pro Simulator (iOS 10.2)
The results are different for the SCNText locations, it seems that every SCNText when run on iOS 10.2 are vertically offset at some constant distance and run on iOS 9.3.5 seems to give the correct results.
This is the testing code:
let testText = SCNText(string: "ABCDEF", extrusionDepth: 0)
testText.font = font
let txtNd = SCNNode(geometry: testText)
txtNd.position = SCNVector3(0,0,0)
rootNode.addChildNode(txtNd)
let bMax = txtNd.boundingBox.max
let bMin = txtNd.boundingBox.min
print("\(bMax)\n\(bMin)")
and the console print output
iOS 9.3.5 is
SCNVector3(x: 0.69833982, y: 0.142382815, z: 0.0)
SCNVector3(x: 0.00214843755, y: -0.00234375009, z: 0.0)
iOS 10.2 is
SCNVector3(x: 0.69833982, y: 1.14238286, z: 0.0)
SCNVector3(x: 0.00214843755, y: 0.997656226, z: 0.0)
