OpenVRML was removed from portage some time ago. Here is an ebuild for the new 0.16.6 version (based on the ebuild from #92690). Currently Java is unsupported in 0.16.6. Compiles fine under amd64.

Ebuild for media-gfx/openvrml-0.16.6
Feel free to reopen if you find a maintainer for this; otherwise you are better off moving it to some overlay, no point in reintroducing ebuilds that were removed due to lack of maintenance. Thanks.
