The Previous Frontier

Remember the mid 90’s…?

.. Primitive fill rate, no texture filtering, no anti-aliasing…..

And games that looked like graphics was the next frontier….

…fill rates

Games that look …cinematic

3D Graphics lets you “look around”

Physics lets you additionally “feel your way” around

Physics is interaction, physics is movement…

Physics is…

Uh, Oh!

Faking physics

A mathematical simulation of phenomena so that interaction follows physics or physics like laws

Force, Collisions, Joints, Cloth, Fluids, Smoke, Gravity, Rigid bodies, Soft Bodies…..

And much more…
