Lazy rendering (also known as lazy evaluation or lazy loading) is when (virtual) objects are not loaded or computed until they are needed. Evidential simulations exhibit lazy rendering in that the value of latent variables are only determined when (and to the extent that) evidence of them is observed.
quotes about lazy rendering
When you reach for your shoes, your shoes will be there.
When you walk through a doorway, the door will be open.
Wherever you go, the floor will continue under your feet.
Every move you make will be made valid.
Everything you see will become real.
Everything you say will become the truth.
