Description

For now this PR changes the display of the IFC model in a probably-not-intended way. I believe after the PR above is merged to IFCjs, that should be resolved.

/cc @agviegas - just FYI!

Converting to draft while the upstream stuff is sorted out.

[agviegas]

I'm submitting this PR. Is there anything I should do regarding this?

[donmccurdy]

Thanks @agviegas! My hope would be that ThatOpen/web-ifc-three#148 can be pulled into IFCLoader, at your convenience. It allows IFC models to display correctly when used in applications that follow the newer color management guidelines.

[agviegas]

Ok, got it! Thanks a lot for the PR. We'll merge it as soon as possible.

@donmccurdy It seems your PR at the web-ifc-three repo has been merged so I guess we can move on with this change, too?

[donmccurdy]

Agreed! I may need help to link the updated IFC loader into the three.js repository first.

[donmccurdy]

The IFCLoader in three.js will need to be updated to the latest version in order to use the new color management APIs. Until then, we do not need this PR.
