Expose ObjectRemovalHelper ?

[jailln]

ObjectRemovalHelper contains helper methods to completely dispose of 3D objects, their material and textures. I think we should expose it in the API since it is quite a common thing that user might want to do when working with 3D objects directly imported with threejs (e.g. gltfs, collada, etc.) and hence it may help them.

As a user I definitely need it :)

WDYT ? @mgermerie

I don't see an inconvenient to expose it. There is just a point on which I need a clarification : only the cleanup method does not need a Layer, and the other methods are called by more "generic" methods (such as the removeLayer from the view, or dispose). As a user, would it be useful to export these methods (those with a Layer parameter) ?

Yep you're right, we should only export the cleanup method
