@greggman I've added its lib here, so it can inspire other developers to build good tools for it :)

[LeviPesin]

Maybe we can add some debug toggle (for example, global variable like window.DEBUG), which will dynamic-import the lib if enabled?

[sunag]

Or maybe THREE.Renderer( { debug: true } )

[LeviPesin]

Yeah... And maybe place renderer.info also under that toggle? Like, it isn't updating (and there is no such property) when it is disabled.

I think debug would be a property for development, info can still be useful for inspection.

@Mugen87 I would like to know if it's ok for you to add uuid in the BufferAttribute?

[greggman]

forgive me if there are good reasons to use UUID in a cache bit just in case you didn't know you can use objects as keys in Map and WeakMap

I don't think *Map would fit in this case, the UUID was an exception to the Hash because it was comparing the Geometry and not the attributes individually, looking closer I think that just simple comparisons should solve it, but I'll have to test it.

[sunag]

Now it looks good :) . Merging...

[Mugen87]

The UUIDs are mainly intended for serialization/deserialization in order to identify shared resources so it's good that you've found a solution without using them^^.
