How did you scan the bottom of the pancake, or did you use the other 3d apps to make the bottom mesh for the object captured pancake ?

How does meta data affect the model creation? When I added image meta data to sample, the created model was changed. this is the code I get meta data from image url: func getImageMetaData(url: URL) -> CFDictionary? {             if let data = NSData(contentsOf: url),                let source = CGImageSourceCreateWithData(data as CFData, nil) {                 let metadata = CGImageSourceCopyPropertiesAtIndex(source, 0, nil)                 return metadata             }             return nil         } when I create photogrammetrySample, this is the code I add meta data to it: if let metaData = getImageMetaData(url: imageURL) as? [String:AnyObject] {                                 sample.metadata = metaData                             }

I have multiple requests in one session, how to stop or cancel the request which is running but not stop or cancel the whole PhotogrammetrySession?
