Change Buffer.Uri type from string to byte[]
C# char is ALWAYS 2 bytes long (UTF-16). Therefore, in cases of loading GLTF files with embedded data (buffer's URI cares model data within it), when you treat the buffer as an array of bytes/ints/floats/etc - the data you read is wrong. The reason is that every second byte's value that you read from such a buffer is zero. Not only data is ill-formatted, but the buffer itself is twice the necessary size.
Please fix it.
P.s. I know it is annoying :) #blame_microsoft. This bug will always haunt people who port C/C++ code to C#.
I assume this is about base64 encoded strings. Are you saying base64 encoded URIs are not working?
when you treat the buffer as an array of bytes/ints/floats/etc - the data you read is wrong
I don't know exactly what you mean by this. Are you casting the string to a byte array directly? C# strings are two-bytes per character to handle Unicode (to a certain extent). If you want to decode the string to a byte array, you can call Convert.FromBase64String to do it.
I have no issues using Convert.FromBase64String. Just need to chop off the front data:application/octet-stream;base64, part.
byte[] bufferBytes = Convert.FromBase64String(buffer.Uri.Substring(37));
Then just use System.Buffer.BlockCopy to get the chunks you need (indices are added to the end so you typically won't want that in your VBO).
