To set the stage: I made a prototype of an app for a company, the app is to be used internally right now. Prototype runs perfectly on iOS, so now I got VP to port the app to its final destination. The first thing I found out is that the image tracking on VP is useless for moving images (and that's the core of my app). Also distance at which image is lost seems to be way shorter on VP. Now I'm trying to figure out if it's possible to fix/work around it in any way and I'm wondering if Enterprise API would change anything. So: Is it possible to request Enterprise API access as a single person with basic Apple Developer subscription? I looked around the forum and only got more confused. Does QR code detection and tracking work any better than image detection, or anchor updates are the same? Does the increased "object detection" frequency affect in any way image/QR tracking, or is it (as name implies) only for object tracking? Would increasing the CPU/GPU headroom make any change to image/QR detection frequency? Is there something to disable to make anchor updates more frequent? I don't need complex models, shadows, physics, etc. Greetings Michal

I'm trying to clone an entity that's somewhere deeper in hierarchy and I want it together with transform that takes into account parents. Initially I made something that would go back through parents, get their transforms and then reduce them to single one. Then I realized that what I'm doing is same as .transformMatrix(relativeTo: rootEntity), but to validate that what I made gives same results I started to print them both and I noticed that for some reason the last row instead of stable (0,0,0,1) is sometimes (0,0,0,0.9999...). I know that there are rounding errors, but I'd assume that 0 and 1 are "magical" in FP world. The only way I can try to explain it, is that .transformMatrix is using some fancy accelerated matrix multiplication and those produce some bigger rounding errors. That would explain slight differences in other fields between my version and function call, but still - the 1 seems weird. Here's function I'm using to compare: func cloneFlattened(entity: Entity, withChildren recursive: Bool) -> Entity { let clone = entity.clone(recursive: recursive) var transforms = [entity.transform.matrix] var parent: Entity? = entity.parent var rootEntity: Entity = entity while parent != nil { rootEntity = parent! transforms.append(parent!.transform.matrix) parent = parent!.parent } if transforms.count > 1 { clone.transform.matrix = transforms.reversed().reduce(simd_diagonal_matrix(simd_float4(repeating: 1)), *) print("QWE CLONE FLATTENED: \(clone.transform.matrix)") print("QWE CLONE RELATIVE : \(entity.transformMatrix(relativeTo: rootEntity))") } else { print("QWE CLONE SINGLE : \(clone.transform.matrix)") } return clone } Sometimes last one is not 1 QWE CLONE FLATTENED: [ [0.00042261832, 0.0009063079, 0.0, 0.0], [-0.0009063079, 0.00042261832, 0.0, 0.0], [0.0, 0.0, 0.0010000002, 0.0], [-0.0013045187, -0.009559666, -0.04027118, 1.0] ] QWE CLONE RELATIVE : [ [0.00042261826, 0.0009063076, -4.681872e-12, 0.0], [-0.0009063076, 0.00042261826, 3.580335e-12, 0.0], [3.4256328e-12, 1.8047965e-13, 0.0009999998, 0.0], [-0.0013045263, -0.009559661, -0.040271178, 0.9999997] ] Sometimes it is QWE CLONE FLATTENED: [ [0.0009980977, -6.1623556e-05, -1.7382005e-06, 0.0], [-6.136851e-05, -0.0009958588, 6.707259e-05, 0.0], [-5.8642554e-06, -6.683835e-05, -0.0009977464, 0.0], [-1.761913e-06, -0.002, 0.0, 1.0] ] QWE CLONE RELATIVE : [ [0.0009980979, -6.1623556e-05, -1.7382023e-06, 0.0], [-6.136855e-05, -0.0009958589, 6.707254e-05, 0.0], [-5.864262e-06, -6.6838256e-05, -0.0009977465, 0.0], [-1.758337e-06, -0.0019999966, -3.7252903e-09, 1.0] ] 0s in last row seem to be stable. It happens both for entities that are few levels deep and those that have only anchor as parent. So far I've never seen any value that would not be "technically a 1", but my hierarchies are not very deep and it makes me wonder if this rounding could get worse. Or is it just me doing something stupid? :)
