Cool demo!

Note about engine future:

1. We currently feature 2 shadow algorithms, [shadow volumes](https://castle-engine.io/shadow_volumes) and [shadow maps](https://castle-engine.io/x3d_extensions_shadow_maps.php).

That’s also something I’d like to investigate 🙂 Note that for trees, TCastleTransformReference and LODs could be very useful to have optimal rendering, see [this news](https://castle-engine.io/wp/2025/03/22/tcastletransformreference-improvements-intuitive-transformation-menu-items-to-duplicate-linked-edit-make-independent-copy-cooperates-with-lod-fixed-tcastlesticktosurface/).
