Support for draco extension
Recently I read about draco extension on gltf,but I was not able to find out proper way to implement this exention on unitygltf repo.I am currently working on app that requires 3d object to be imported at runtime effectively and very fast. I find draco extension is the only way to acheive this and I have gone through papers on internet but was not able to figure out how to implement this .Please anyone can assist how can I start implementing draco extension on gltf
vote +1 for this extension support, Microsoft has used draco in it's Microsoft.glTF.CPP pipe-line.
@bghgary That extension loads draco compressed geometry (.drc files and buffers), which does not include textures. Supporting draco compression in gltf/glb would be a huge win for this module.
@boblaublaw The original question is how to implement the draco extension in this project. The link I sent should help with that.
Since draco is c++, I'm guessing it has to be built as a plugin for different platforms. What platforms should it include? Windows, macOS, iOS and Android for example?
Yeah wrapping the existing plugins in the work from the repo that Gary linked would be a good start
Well I looked around, for once, the existing plugin doesn't have a compressing method yet (only decompression) so it will need to be worked out. Second, if I understand correctly, the extension is supposed to replace the bufferViews with their decompressed equivalent, which will need to be done in the loader and not the extension, which is weird and hacky. I guess the current architecture of UnityGLTF doesn't allow much flexibility to do things. Am I missing something?
Hi guys ! If someone here is still looking for this extension (for a long time like me), take a look at this awesome GLTF importer alternative : https://github.com/atteneder/glTFast I just found this and with simple fixes, I make it working ! Hope this helps ;)
