    to my code.
  • This PR changes Open3D behavior or adds new functionality.
    • Both C++ (Doxygen) and Python (Sphinx / Google style) documentation is
      updated accordingly.
    • I have added or updated C++ and / or Python unit tests OR included test
      results
      (e.g. screenshots or numbers) here.
  • I will follow up and update the code if CI fails.

I consider to be better PR that some changes are in my big PR. You can analyze them and copy to this PR:
@ssheorey you can copy my files from this PR:
#7272

    1. Upgrade filament to build with >=22.04
    1. Upgrade requirements from Open3D-ML to match with this PR
    1. Upgrade macos-14 --> 15
    1. Use cuda 12.8 and newer cutlass for blackwell
    1. Upgrade openblas to fix some issues in arm
    1. upgrade eigen to 3.4 stable release version
    1. OpenML files must be upgraded to fix issues with newer eigen

EXTRA:
IT WOULD BE COOL to do compatible with last filament 1.61.1, in my PR is compatible with <1.54

Fixes to building docs and macOS Intel wheel.
