Consider disambiguating resource names

[javagl]

When resources (like external buffer- or image references) are created via the options.separate flag, then their names are assigned automatically. This is happening around writeResources.getName. The names are somewhat generic - something like buffer0.bin. One could consider prefixing these names with the base name of the input file, to disambiguate them. For example, when processing a Duck.glb, the files could be named Duck_buffer0.bin.

(The use case is that one might to batch-process multiple files in one directory, and write the results into one directory. When the input files Duck.glb and Triangle.glb both generate a buffer.bin, then the user has no obvious way to handle this: The separateResources do contain the names like buffer0.bin as the key, but this cannot be changed at the client side - at least not without manually doing some hacky gltf.buffers[i].uri = myNewName).

It should already prefix with the base name of the output file. E.g. if I run

node bin/gltf-pipeline.js -i ./specs/data/2.0/box-textured-embedded/box-textured-embedded.gltf -o ~/Desktop/box.gltf --separate

I get three files:

• box.gltf
• box.bin
• box0.png

If you're calling processGltf or equivalent programmatically you'll need to pass in options.name for it to get prefixed.

pass in options.name for it to get prefixed.

That was the missing piece.
