I feel like I should apologise for the headline but Nvidia call their middleware physics engine PhysX, for crying out loud. ‘Making a splash’ is almost Nabokovian in comparison. You may recall recent advances in convincing/crazed coiffures and I care about that about as much as I care about the latest floppy-fringed hair fashions in the real world. Not a jot. Fluid physics though? Ever since the invention of physics, which was sometime just before I balanced bricks on a plank to create a see-saw bridge in Half Life 2, I’ve been waiting for a game with proper water. The latest PhysX tech demo got my juices flowing and you can see it below.
