Manifold Garden Case Study

If you understood how portals are implemented through the earlier article on portals to visible spaces, it seems possible to implement the infinitely falling space that appears in Manifold Garden using a similar approach.

• There are portals with very large surface areas on both the ceiling and the floor.
• The space seen through the floor portal may recursively show additional layers of the space visible through the floor portal, and handling this properly would be the key challenge. In the game, we can see that distant spaces are rendered with a foggy effect.
