GLTF importer with C++ Qt

I have started writing a GLTF parser with Qt for my pet project (a multi plateform game engine) and so I initially used the Json system : https://github.com/this-engine/this/blob/qt-this/src/extra/gltf_importer.cpp
But I've noticed Qt already has a GLTF parser in the Qt3D module. Unfortunately I don't see how to use it without using Qt3D as my renderer.
Anyway I'm stuck at trying to read a data URI :
"uri" : "data:application/gltf-buffer;base64,AAAIAAcAAAABAAgAAQAJAAgAAQACAAkAAgAKAAkAAgADAAoAAwALAAoAAwAEAAsABAAMAAsABAAFAAwABQANAAwABQAGAA0AAAAAAAAAAAAAAAAAAACAPwAAAAAAAAAAAAAAQAAAAAAAAAAAAABAQAAAAAAAAAAAAACAQAAAAAAAAAAAAACgQAAAAAAAAAAAAADAQAAAAAAAAAAAAAAAAAAAgD8AAAAAAACAPwAAgD8AAAAAAAAAQAAAgD8AAAAAAABAQAAAgD8AAAAAAACAQAAAgD8AAAAAAACgQAAAgD8AAAAAAADAQAAAgD8AAAAACAAKAAwAAAAAAIA/AAAAQAAAAAAAAEBAAABAQAAAAAAAAKBAAACAQAAAAAA=",
for now, I've detected the type, the base, but how to interpret that long string and convert it to a
Did anyone tried doing gltf import? Did you succeed? Am I missing an obviously simple solution?
Thank you in advance !
Hi and welcome to devnet,
As the string suggests, it's base64 encoded. Therefore you can use QByteArray::fromBase64 to load the data that is available after the "base64,".
